You would figure that in Seattle, we have to know about waterproofing. You are right! Since 1917, Atlas Supply has been the Northwest’s leading supplier of waterproofing products and materials. Atlas Supply stocks a full range of above grade and below grade waterproofing materials and systems, to meet all of your demanding waterproofing needs. Waterproofing products and materials include:
- Sheet and liquid applied membranes
- Cementitious coatings
- Water stops
- Penetrating water repellents.
Drainage and Protection Systems
These drainage composites give construction professionals a high performance, prefabricated drainage media that is designed to retain soil while allowing water to collect and pass through to its core, and away from your building. In addition, drainage composites provide lasting protection to the waterproofing membrane system.
Roofing Underlayment and Self-Adhered Flashing by GCP Applied Technologies (formerly Grace)
GCP Applied Technologies’ popular Ice & Water Shield is a sloped roof underlayment that provides a highly effective barrier against leakage resulting from ice dams or wind-driven rain. Similarly, the GCP Applied Technologies self-adhesion flashing systems are the products of choice for sealing leaks around windows, doors, corner boards, sills. Apply sloped roof underlayment anywhere there is an opening or area susceptible to water, air and moisture penetration.
Sheet Applied Membranes
Waterproofing applications such as for foundation walls, plaza decks, parking and bridge decks, tunnels, interior slabs, planters, laboratories and mechanical rooms and balconies, the popular GCP Applied Technologies Bituthene® membranes are applied to the positive side of structures to stop water before it hinders the structural elements of a building. For Blind Side waterproofing applications, GCP Preprufe® membranes form a continuous mechanical bond to concrete that is cast against it. These membranes are installed against soil retention systems or applied over mud slabs or compacted soil before the concrete structure is poured. Applications include foundation walls, under slabs, and tunnels.
Bentonite Clay and Sheet Membranes
These waterproof membranes include the popular MiraClay®, a bentonite clay membrane technology which consists of a uniform layer of sodium bentonite clay that is sandwiched between a durable puncture resistant non-woven polypropylene fabric. These membranes are designed for waterproofing below grade structural slabs. Advantages include self healing if ripped or punctured, tremendous impermeability and excellent resistance to chemicals, and the ability to expand and seal cracks in concrete. The Carlisle® sheet membrane waterproofing systems consist of a self-adhering asphalt laminated to polyethylene, which forms a heavy 60 mil. protective membrane system.
Waterstops typically are used in nonmoving joints to create watertight concrete joints such as many types of cast-in-place and precast below grade concrete applications. These waterstop systems are construed, chemically modified, natural rubber strips with embedded wire mesh which eliminate unnecessary expansion and prevent “winding” action when fastened to concrete. Also at Atlas Supply, you will find water-swelling waterstops that are a caulk-type single component hydrophilic compound used in water-stop repair applications and new construction.
Industrial Strength Elastomeric Membranes
Used with outstanding success as a lining for potable water storage tanks, these two-component systems allow for expansion and contraction over a broad temperature range and maintain flexibility and waterproofing properties under continuous exposure to water above or below grade.
Liquid Applied Waterproof Membranes
These liquid applied membranes consist of a single component, moisture-curing, bitumen-modified polyurethane system that bridges cracks up to 1/4 inches and guards against pinholes. Typical applications include above-grade between two-course concrete and within cavity walls, parking garages, fountains and pools, sea walls, dams, reservoirs and many more.
Protective Waterproofing Slurry Seal by Sika™ Corporation
This is a two-component, polymer-modified, cement-based, protective and waterproofing slurry coating suitable for use in both interior and exterior applications. Main uses include internal and external waterproofing and dampproofing concrete, mortar blockwork and brickwork.
Penetrating Water Repellent Sealers
These high-performance, clear, water-based, silane/siloxane systems are designed for vertical concrete, brick and other masonry surfaces. Advantages include providing for the highest degree of water repellency, VOC compliant, environmentally friendly, breathable, does not alter surface appearance, and is easy to apply. These and other penetrating water repellent products you will find at Atlas Supply are specifically designed for various concrete and masonry surfaces and environmental conditions. Apply on horizontal surfaces used on stadium floors, food courts, plazas, parking garages and other interior and exterior applications.
