Air and Vapor Barriers – While not technically considered “waterproofing,” installation of these assemblies involves processes very similar to those used in waterproofing applications. Air and vapor barriers are a key part of the building envelope. They control the effects of moisture and enhance a building’s energy efficiency.
Blindside – Blindside waterproofing refers to a process commonly used in construction of new foundations. Waterproofing materials are installed prior to installation of concrete slabs and walls. These materials are specially formulated to bond to the new concrete when it is poured. They are made from a variety of materials, including bentonite and HDPE (high density polyethylene).
Coatings – There is a large variety of fluid-applied coatings used in waterproofing applications. These products can be used to waterproof containment tanks, planter boxes, water features, and decks.
Crystalline – Crystalline materials are applied in a slurry coat over concrete slabs and walls. These crystals embed themselves into the concrete, creating a watertight condition.
Grout Injection – Injection is a process most commonly used when the waterproofing of a building’s foundation fails, and the exterior of the basement walls cannot be exposed to resolve the issue. A variety of waterproofing materials can be injected into the concrete, filling cracks and voids in the concrete itself, as well as openings and voids in the materials beyond the basement wall, creating a watertight environment.
Hot Applied Rubberized Asphalt – Often referred to as simply “hot rubber,” these membranes can be useful in a large variety of conditions. They are commonly used as deck membranes where a concrete slab, landscaping, or paver system will be installed over the membrane.
Sheet Applied – Many of the most common waterproofing membranes come in the form of a self-adhering sheet. These sheets are used in conjunction with fluid-applied membranes to create a watertight seal. Sheet-applied membranes can be installed almost anywhere, including below grade walls, decks, and planter boxes.
Shot Crete Applications – Due to advantages in time, ease of installation, and cost, shotcrete has become one of the most popular methods of concrete installation. For several reasons, shotcrete applications are much more difficult to waterproof than cast-in-place concrete. Standard blindside waterproofing applications have not held up when used in conjunction with concrete. Several manufactures have designed products specifically for use in conjunction with shotcrete.
Traffic Bearing Membranes – Certain waterproofing applications call for a membrane to function beyond water tightness. In some situations, a waterproofing membrane must serve as the finish surface of a deck, or accommodate pedestrian or vehicular traffic. We have many durable products which can accommodate these needs.
