Use this 3-part SimpleSpecs™ specification template to specify panelized or composite sheet form bentonite waterproofing at below-grade, under the slab, and split slab construction.
What is it?
Bentonite waterproofing is a type of waterproofing material that is widely used in the construction industry. It is made from clay minerals known as smectites, which have the unique ability to swell when they come into contact with water, creating a barrier against moisture.
Bentonite waterproofing is important because it provides a reliable and cost-effective way to prevent water from penetrating buildings, structures, and foundations. Moisture infiltration can cause extensive damage to structures, including mold growth, wood rot, and foundation settling. Bentonite waterproofing acts as a barrier to keep water out and protect against these issues.
One of the key differences between bentonite waterproofing and cold or hot fluid applied waterproofing is that bentonite is a self-sealing material. When the bentonite clay swells, it forms a tight seal around any cracks or gaps in the surface it is applied to. This makes it particularly effective at preventing water from infiltrating buildings, even in areas where there may be some movement or settling.
Cold and Hot Fluid Applied
Cold or hot fluid applied waterproofing is a process used to protect buildings and structures from water penetration. This method involves the application of a liquid membrane, which is either cold or hot, to the surface of the building. The membrane creates a waterproof barrier that prevents water from seeping through the surface and into the building.
Cold fluid applied waterproofing involves the use of a liquid membrane that is applied at ambient temperatures. This method is particularly useful in situations where the use of heat is not practical or safe. Cold fluid applied membranes can be applied to a variety of surfaces, including concrete, metal, and wood.
Hot fluid applied waterproofing involves the use of a liquid membrane that is heated to a high temperature before application. This method is particularly useful in situations where a more durable and long-lasting membrane is required. Hot fluid applied membranes are applied to concrete surfaces and can withstand high levels of foot traffic and heavy loads.
Both cold and hot fluid applied waterproofing methods offer a range of benefits. They are easy to apply, provide excellent protection against water penetration, and can be used in a variety of different applications. In addition, they are both environmentally friendly and cost-effective.
In contrast, cold or hot fluid applied waterproofing typically relies on a chemical reaction or heat to cure and create a waterproof barrier. While these methods can be effective, they may not be as reliable as Bentonite waterproofing in situations where movement or settling is a concern.
