Creates a drainage/ventilation cavity environment behind natural and manufactured stone veneer walls. Styrene-butadiene rubber compounds cure to a flexible, rubbery consistency. The higher soil temperatures on the exterior also create the need to provide at least a damproofing on the exterior of the foundation wall to resist the strong interior vapor drive. One of the reasons that builders may stick with simple dampproofing is cost, says Steve Geiger, product group manager for W.R. Meadows. Distribution systems within the foundation walls themselves must be treated with careful consideration, as they can also be conduits transporting air and moisture within the structure. The liquid is the carrier, says Russ Snow, sales manager and product group manager for W.R. Meadows, but the products are essentially the same once the liquid has evaporated and the coating has cured. Coarse sands varying from No. 3-D Drainage Mat for Advanced Moisture Protection in Exterior Wall Systems FEATURES/BENEFITS Product Information Sheet . The modal window is a 'site map' of the most critical areas of the site. TREMDrain 1000 NW is used with TREMproof and Paraseal waterproofing membranes serving both as a protection course and replacement for traditional pipe and stone drainage systems. Request Online $ Volume Pricing on Large Orders Aggregate backfill needs to be trucked to the site and the dirt backfill hauled from the site. Distribution FunctionsFoundation walls may contain distribution systems such as electrical and electronic runs. Most of the time, waterproofing is not needed residentially.. Tremcos HDPE/Bentonite is typical of these products. However, the use and location of the insulation is more important on the control of moisture in terms of preventing condensation on interior wall faces for the entire height of the foundation wall. Dampproofing materials are generally applied by sprayer, roller, brush, or trowel and are often bitumen based coatings; typically applied up to 10 mils (0.25 mm) in thickness. See appropriate sections under applicable guide specifications: Unified Facility Guide Specifications (UFGS), VA Guide Specifications, Federal Guide for Green Construction Specifications, MasterSpec. The latter two should not be used as waterproofing except for the most non-critical conditions. Contents: [ show] Components and Working of Foundation Drain Waterstops should be utilized at construction joints in below grade walls, footings, slabs, and other elements where a waterproof system is required. Hot applied, rubberized asphalt systems can be 125 mils to 180 mils thick, plus embedded 60 mil neoprene sheets. SikaBit Post-Applied Self-Adhered Membranes, Sika Drainage Mat 400 / 420 / 720 / 1000 / GRS, Sikaplan Pre/Post Applied Loose-Laid Membrane, SikaProof Pre-Applied Fully Bonded Membrane, SikaProof Post-Applied Waterproofing Membrane, SikaBit Post-Applied Self-Adhered Membrane, Variable flow and compressive strength configurations, High crush resistant configurations for vehicular traffic, Pre-assembled filtration and membrane protection layers. Mat Type; Drainage: Interlocking: Traction: Antifatigue . Asphaltic coatings are very common. Positive-side systems are available in numerous materials and forms. Vertical loads exist from the dead, live and lateral loads from the structure and the wall itself. On low risk sites where free-draining backfill and perimeter drains are provided, especially where basement use is limited, dampproofing may make sense to a developer looking for any way to cut costs. <>stream HYDRODUCT 220 is a strong, preformed 0.44 in. But experts caution against coating an entire wall with a urethane or epoxy sealer that is not vapor permeable. One difference is that 16-inch sections of the slab are left intact every 15 to 20 feet to keep the foundation wall stable, as the illustration below shows. With drainage, both of these procedures are eliminated.3. Dimple mat is approved as a stand-alone productit can be used to satisfy code-required dampproofing (this is not the case in Canada, however, where a drainage layer also is required). Soil loadings vary with soil type and whether soil is treated as active or passive. Drainage mat can be fitted with outlets and drainage accessories to further move the water away from the structure. These are EnkaDrain foundation drainage mats. Drainage pipe at the perimeter of the foundation wall should be surrounded by a free draining granular material that is wrapped in filter fabric to prevent fines from filling in the porous spaces of the granular material. Peel-and-stick and liquid-applied membranes are common on residential sites, but manufacturers offer several other options. National Institute of Building Sciences Sika Drainage Mat September 2019, Version 01.03 020816110010000003 PRODUCT DATA SHEET . Most building codes require dampproofing as a minimum amount of moisture protection. DELTA-MS is a dimpled membrane that uses our exclusive Air-gap Technology to ensure your basements stay dry and last longer. UGL Drylok Extreme is guaranteed to resist 15 feet of head and last for as long as 15 years. PVC and polyethylene pipes are available in smooth or corrugated configurations and are slotted on the bottom half of their cross-section to allow water infiltration. This excess moisture might be due to flooding or some other reason. Disclaimer, Unified Facilities Guide Specifications (UFGS), Unified Facility Guide Specifications (UFGS), Federal Guide for Green Construction Specifications, Energy-Efficient Products and Technologies. Geotextile filter fabrics are also used for separating differing soil types in below grade enclosure applications. by Mark Postma, PE, Carl Walker, Inc. Whatever thickness you get is whatever the guy puts on.. Waterstops are manufactured products available in a wide range of configurations and sizes. Bentonite clays act as waterproofing by swelling when exposed to moisture thus becoming impervious to water. Where grade slopes down along an exterior wall, the waterproofing will step down incrementally so that it continues to protect the below grade, occupied space. If water gets through the dimple sheet, the dampproofing will prevent it from being absorbed by the concrete. The use of a Tremco drainage mat provides the following advantages: 1. One of them, Texas-based Matt Risinger, starts with a liquid-applied or peel-and-stick membrane that is applied directly to the foundation wall (he fills any large voids with mortar first). Although the composite board may have a polyethylene sheet on the membrane-side, this sheet is often cut, damaged, or missing. Waterproofing Systems. Contact. This section provides specific description of materials and systems common in foundation walls and below grade building enclosure systems in general. Common areas of concern for waterstops are at corners and laps in the materials. An interior drainage layersuch as dimple mat or sheet waterproofing membranecan be added. The drain board protects the waterproofing layer while relieving hydrostatic pressure. Sika Drainage Mat 420 and 720 consist of an impermeable high flow dimpled polypropylene drainage core heat-bonded to a layer of non-woven polypropylene (420) or woven polypropylene (720) filter fabric on the top side and a polyethylene membrane protection film on the bottom side. If heat-welded seaming is employed and loose-hung membranes are tough and protected from damage by protection board, they may be effective waterproofing materials, but if a leak occurs, the leak will be difficult to locate and correct due to the loose application of the waterproofing layer in those cases. Sealing these generally requires application of elastomeric boots that seal to the housing and to the exterior pipe. For most portions of the foundation wall, water removal and control is of prime importance. The details associated with this section of the BEDG on the WBDG were developed by committee and are intended solely as a means to illustrate general design and construction concepts only. They can be applied with a sprayer or with a brush, and in many parts of the country thats all the foundation walls will get in the way of moisture control. The use of a Tremco drainage mat provides the following advantages: 1. Readers are advised to obtain expert advice when designing systems which are below the water table or which are enclosing particularly vulnerable occupancies. If installed, soil pressures can cause the "dimples" in the drainage core to displace or damage the waterproofing membrane. Most waterproofing materials also control vapor diffusion. As moisture moves from the upper screen through the drainage system on the exterior towards the exit drain, moisture will inevitably make its way toward the surface of the foundation wall itself. Drainage Mat 202. Bentonite ClaysThese systems include composite sodium bentonite systems with HDPE liners and geotextile fabrics, which are more common and more effective than the traditional systems. 1090 Vermont Avenue, NW, Suite 700 | Washington, DC 20005-4950 | (202) 289-7800 In soils that go through repetitive wetting and drying cycles, the panels eventually show signs of wear and become less effective than if they had stayed wet all the time. Stopping water leaks in an existing foundation is more complicated. In general, when properly designed, non-woven products have good filtration and separation properties. The affable pitchman stands beneath an oversized umbrella and promotes a business devoted to all things basementy. Hafford is one of hundreds, maybe thousands, of specialists around the country who have made careers out of rehabbing wet, moldy basements and crawlspaces. The outlet must be the lowest point in the system at each juncture. Hydrostatic pressure loads may exist in cases of high water tables or flood events. For surface moisture loadings such as rain and snow, the first line of control is the upper screen at the exterior surface. Holes in drainage mats allow water and other liquid hazards to pass through the top of the mat, reducing the likelihood of injury from slipping. If PVC is used, corners and laps should be heat welded and properly inspected. The removal of the moisture in the most complete and expeditious manner will decrease the probability for intrusion of water. Caution is advised with use over softer liquid applied materials as the drainage layer may dig into and breach the membrane. In many foundation wall situations with low water table elevations, the combination of the upper screen, the exterior drainage system, the near surface drainage system and the exit drain will control the majority of the water. It is a high-density polyethylene sheet combining recycled and virgin materials whose surface is studded with 5/16-inch-tall dimples. The thickness of these systems varies from 20 to 120 mils. All drain tile piping should be laid onto large, river-washed aggregate stones, which is laid onto a filter fabric, which should be wrapped around and over the drain tile to try to prevent fine soils from filling the drain tile. . Based on some extensive excavation and waterproofing experience, it has been found that corrugated PVC drain tile piping can collapse under the weight of backfill, and the preference is to use stiffer PVC pipe if possible. The general solution to the problem is encasing the foundation in a waterproof membrane with seams sealed, and then having a drain tile to prevent water from rising around the foundation, which would create hydrostatic pressure that could aid water incursion through any small breaches in the membrane. Combining different moisture control layers is popular with a number of builders. . All rights reserved. Dampproofing resists the passage of liquid water that is not under hydrostatic pressure, which is the case when the foundation is backfilled with a well-draining material and is not subjected to standing water. When the basement is used only for storage or mechanicals, a little water once in a while may not be a big deal. Positive drainage should be established underneath structural slabs with crawl space. Drainage mat allows for full head-to-footer flow of water. One is that they will not span any cracks that develop in the foundation walland foundation cracks are viewed as all-but-inevitable. Find Your Sales Rep location_on. It happens when water gets inside the concrete (or brick or stone) and then pushes it outward. ArmorDrain 150 Drainage Mat is considered a green product, and can be used toward LEED building credits. endstream These systems include metallic (metal oxide), crystalline, chemical additive, and acrylic modified systems. Sika Drainage Mat 1000 is suitable for heavy loads and split slabs exposed to vehicular traffic. However, a double coat of this paint-like material was not enough to prevent some water from seeping out at the bottom of the column. The core is perforated, then bonded to a root resistant non-woven polypropylene filter fabric on the top side and nonwoven polypropylene membrane protection fabric on the bottom side. Where the foundation wall is required to be waterproofed, adding a waterstop to the construction joint is recommended. The TREMDrain is used with TREMproof and Paraseal waterproofing membranes serving both as a protection course and replacement for traditional pipe and stone drainage systems. Become a member and get unlimited site access, including the For many membrane types, a multiple layer detailing of the membrane, proper isolation and allowance for joint detailing is generally effective for construction joints. Peel-and-stick membranes are sold by a number of companies under a variety of trade namesBlueskin WP 200 from Henry, for example or Mel-Rol from W.R. Meadows. Trusted, comprehensive guidance from the pros for a home that is healthy, comfortable, and energy efficient. Some systems include reinforcing mesh embedded into the liquid. In general, the manufacturer's standard details should be followed. Asphaltic coatings may be solvent- or water-based. Non-woven products are typically continuously extruded and spun and then needle-punched to create uniform openings that can be selected depending on the design. Foundation Membrane Material Plastic Coverage Area 520 square foot Thickness 5/16 inch Overall Length 780 inch Overall Width 96 inch Compatible Surfaces Concrete Block, Concrete Shipping Dimensions 96.00 H x 12.00 W x 12.00 D Shipping Weight 70.0 lbs Return Policy Regular Return (view Return Policy) 8['rg4qIxg5"~;7qS~Q>090W BO9W;%5S"$q07.. If the climate receives more than 20 inches of rain annually, a drainage mat at least inch thick should be installed over the water control layer. In these cases the remaining part of the system is a dampproofing applied directly to the exterior surface of the foundation wall. Repairs from the outside involve digging a trench on the outside of the foundation, adding perimeter drains if they do not already exist, and adding dimple mat or another type of membrane to the outside of the foundation wall. Structural Support FunctionsThe foundation wall system of the below grade building enclosure must be designed and constructed to support both vertical and lateral loadings. In the upper areas of the foundation wall thermal loading considerations must be addressed. Early morning TV viewers in Portland, Maine, sooner or later will meet Tony Hafford, founder of T.C. The key advantage to fluid systems is their monolithic nature and self-flashing abilities as the material is applied in liquid form. Drainage mat can be fitted with outlets and drainage accessories to further move the water away from the structure. Get home building tips, offers, and expert advice in your inbox. Attach mat to membrane surface with Sikaflex 11FC or approved adhesive as necessary to keep in position. In many applications the interior finish is simply the interior surface of the material used for the foundation wall, i.e. concrete, insulation may only be of importance to moderate interior temperatures in the upper portions of the foundation wall where temperature conditions will fluctuate. Waterproofing membranes can be categorized into four (4) types: Fluid-Applied SystemsThese systems include urethanes, rubbers, plastics and modified asphalts. They include flexible cementitious coatingssuch as W.R. Meadows two-part Cem-Kote Flex STand panels made with a layer of sodium bentonite (a variety of clay) that expands to form a watertight barrier when it gets wet. However, since some municipalities charge for water pumping into storm drain systems, these costs must be weighed over the life of the structure when designing the waterproofing systems. The geotextile keeps sediments out, and the textured surface of the membrane creates an air gap to relieve hydrostatic pressure. This assembly, what he calls the biggest bang for the buck, should be able to cope with relatively wet conditions and work on all but the most challenging sites. The following details can be downloaded in DWG format or viewed online in DWF (Design Web Format) or Adobe Acrobat PDF by clicking on the appropriate format to the right of the drawing title. When using cast-in place concrete, detailing of the form ties is critical and using single sided forms braced back to the slab can minimize this detailing. Detailing around shoring piles and soil tie-back anchors can be challenging and reducing the number or frequency of these types of penetrations will increase the potential for good performance of the waterproofing system. Hot applied, rubberized asphalt systems can be 125 mils to 180 mils thick, plus embedded 60 mil neoprene sheets. As explained by Matt Stock, president and owner of U.S. Waterproofing, a Chicago-area company, its possible to dig outside the foundation to expose a crack with a shovel or post-hole digger, then treat the area with bentonite. WaterWay Rainscreen Drainage Mats: Consists of a polypropylene core of fused, entangled filaments in varying thicknesses from a nominal 1/8 inch to 3/4 inch, depending on desired cavity space and cladding selection. of RDH Group, Scott A. Harvey, AIA, RWC, LEED AP of Applied Building Sciences, and Joshua Kelly of Simpson Gumpertz & Heger Inc. United States of America Careful attention to installation is critical during both cast-in-place and shotcrete applications in blind-side waterproofing assemblies. A few thousand bucks up front on a site where conditions are questionable seems like good insurance. Clean surface of loose debris and install Sika Drainage Mat directly on Sikalastic RoofPro and Sikalastic-320 NS/SL membrane with filter fabric side up and membrane protection layer down and in the direction of maximum slope. These walls may also be used in the lateral resisting system for the building. It is recommended that a 60 mil PVC membrane or polyolefin membrane be used, set on a concave sand bed and fastened to the foundation wall with a stainless steel termination bar with standard waterproofing applied to the wall above that point. This can be accomplished with pumping systems. With fluid membrane systems, proper application in terms of coverage and thickness is critical to performance, and this should be monitored throughout the installation. Waterproofing is more effective in eliminating the risk of leakage and may be no more expensive than dampproofing, depending on the material used. Other available dampproofing technologies include both cementitious and reactive products. Typically constructed with flexible PVC, permeable grout injection tubes are installed in construction joints and are injected with grout only if leakage is observed. SKU 3811R-GR. Sika Drainage Mat 1000 Sika Drainage Mat 1000 consists of a high density polyethylene geonet drainage core with its ridges heat fused to a layer of nonwoven polypropylene filter fabric on the top side and a heavy duty non-woven polypropylene membrane protection fabric on the bottom side. Diligent inspection and repair of the waterproofing after reinforcing steel is placed is a critical step, as steel placement often results in damage to the waterproofing that can not be repaired once concrete is placed. The Foundation Protection System that Keeps Basements Dry Protecting your foundations from water and moisture is critical. The effectiveness of this initial screen in shedding moisture may influence the design of the other components of the system. The TREMDrain Series consists of prefabricated drainage mats for vertical and horizontal applications with a variety of combinations of filter fabrics, drainage cores and protective polymeric film and a Total-Drain System to replace perforated pipe/aggregate collection systems. Assisting were Judd Peterson of Judd Allen Group and David Young, P.Eng., P.E. ASTM D6525 Composite Thickness 0.27 (6.8) in (mm) ASTM D3774 Core Width 48 (1.2) in (m) NA Roll Weight 16.0 (7.2) lbs (kg) NA Roll Length 50 (15.2) ft (m) Dampproofing is not intended to control liquid water leakage through the foundation wall; waterproofing is required to control water leakage. f The drain should be placed below the top of the footing. Gap-grading the sand provides uniform grain size, which accelerates drainage flow rates. Cementitious SystemsThese systems contain Portland cement and sand combined with an active waterproofing agent. Then he filled the hollow cores of the columns with water to see whether the coatings worked. For uneven rubble foundations, a layer of spray foam insulation can be applied over the waterproofing membrane, as the illustration below shows. endobj Typical hydrostatic and soil pressures generally range from 30 to 62.4 psf per foot of depth. Basements are increasingly becoming in-law suites, man caves and home theaters where finish materials rival those in above-grade parts of the house, Straube says. For positive side applications, the installation of protection boards or insulation layers as quickly as possible after membrane installation is critical to prevent mechanical damage form subsequent layers and backfill and form ultraviolet radiation. It combines bentonite and a high-density polyethylene sheet that is installed on the outside of the foundation before backfilling. The filter fabric helps prevent roots from affecting the efficiency of the drainage/aeration layer as well as retaining soil or other fine particles from being washed away and allows water to pass into the drainage core. A variety of sheet- and liquid-applied membranes can be used, all designed to resist the hydrostatic pressure of ground water. Approved materials include bituminous coatings (asphalt that has been diluted with solvents) acrylic modified cement, or surface-bonding cement. Design considerations include selecting an appropriate design to achieve the required flow rate. Condition appraisals and trouble shooting of below-grade structures reveals common sources of leakage that occur at penetrations. Generally, waterproofing can only be eliminated in sites with exceedingly dry soil. The lens membrane should slope away from the building and collect and redirect the runoff to a drain tile or sump away from the foundation.

Understanding the specific chemical admixture is important in determining its potential performance in below-grade dampproofing or waterproofing applications. The information contained therein is not intended for actual construction, and is subject to revision based on changes and or refinements in local, state, and national building codes, emerging building envelope technologies, and advancements in the research and understanding of building enclosure failure mechanisms. In all cases, installing a perimeter drain below the level of the basement floor is essential. Its often used as part of a waterproofing assembly. Structural Support, Environmental Control, Finish, and Distribution as they relate to the below grade enclosure elements of foundation walls. Aggregate adds additional weight-bearing to the foundation wall. Shotcreting can result in undesirable conditions such as voids behind reinforcing steel, and as a result some waterproofing manufacturers do not recommend their products for this application. The key question that remains is whether to provide dampproofing or waterproofing to the surface of the foundation wall or not at all. While the first control of these abnormal load events are through security entry control systems and restricted access, structural design considerations may also be required in the design of the foundation wall system. Drainage pipe should have a slope of at least 0.5%, but preferably 1.0%. Thats the thinking behind Risingers approach, and Stocks experience on the retrofit side would seem to back him up. Basic Uses TREMDrain NW is ideal for vertical walls less than 20 feet. To do so, Peter built hollow columns of 8-by-8-inch masonry block and waterproofed the outside according to directions provided by the manufacturer. Waterproofing membrane systems are available as either post-applied or pre-applied products for use in either positive-side, negative-side, or blind-side applications. Negative systems are generally limited to cementitious systems. Where sheet materials are utilized, it is preferred to adhere the membrane fully and continuously to the substrate to prevent lateral migration of leaks, and to heat-weld or positively bond the seam laps. A little bit of water might get through at a puncture or nail hole, but a little water shouldnt be a problem. Imperfections in the sprayed coat are repaired or filled with the sealant (Risinger recommends Poly Wall 2200). (This assembly looks a lot like an above-grade rainscreen wall, with the dimple mat taking the place of exterior cladding, and the dampproofing filling the role of a water-resistive barrier.). Hafford Basement Systems. The performance of liquid-applied and sheet membranes is the same, he says, and costs are similar. Dampproofing is always applied on the positive side, or wet side, of the structural element. With drainage, both of these procedures are eliminated. This is accomplished through a drainage system at the exterior of the wall that is typically a free draining granular material. <>stream Start your subscription today and save up to 70%. With some coaxing, the two crystalline coatings did keep water out. Home. The material may have polyethylene film on one side and a glass mat surface on the other side. Sika Drainage Mat 1000 Sika Drainage Mat 1000 consists of a high density polyethylene geonet drainage core with its ridges heat fused to a layer of nonwoven polypropylene filter fabric on the top side and a heavy duty non-woven polypropylene membrane protection fabric on the bottom side. If the builder is treating 1,000 square feet of foundation wall, the cost would be $1,000 vs. $220 (without factoring in labor). Backfilling should commence as soon as possible after installation of the drainage mat. . Another way of tackling leaky basement walls is by using a waterproofing coating on the interior. Fluid-applied membranes are applied in liquid form and cure to form one monolithic seamless membrane. Liquid-applied waterproofing membranes may come in several grades, with a manufacturers better-quality products guaranteed for greater amounts of hydrostatic head. Waterproofing membranes are predominantly applied to the positive (exterior) face of the foundation wall, however, there are negative-side waterproofing systems that can be applied to the interior of the foundation wall, and blind-side waterproofing systems that can be pre-applied to a support-of-excavation wall resulting in a waterproofing system installed on the positive side.
