What is cold applied waterproofing?

Briefly defined, cold-applied systems are waterproofing or roofing applications that utilize a cold adhesive (solvent-based or water-based) in the adherence or fusion of the felt. Cold-applied roofing and waterproofing systems have been available in the U.S. markets for more than 50 years.

What is cold fluid applied waterproofing?

Cold fluid applied waterproofing products are an ideal solution for applications where complete coverage with a sheet membrane is unlikely. These fluid membranes can be either single or plural component or they can be two coated and reinforced membranes.

Where is cold fluid applied waterproofing used?

Most fluid-applied waterproofing products are installed outdoors in applications such as rooftops, fountains, planters, below-grade foundations, lagoons, secondary containment basins, and plaza/decking systems, so weather conditions is a critical consideration.

What is hot applied waterproofing?

Hot rubberized waterproofing systems are fluid-applied membranes that consist of a blend of asphalt and modified rubber polymers containing mineral stabilizers. These waterproofing systems allow for creating monolithic membranes that can cover a large surface area.

What is cold-applied bitumen?

Cold adhesives are generally composed of bitumen, solvent, fibers, fillers and stabilizers; some may also contain rubber polymers such as SBS. As the solvent evaporates from the adhesive, the remaining components bond to the modified bitumen surface of the membrane by a type of solvent weld.

Cold Applied Bitumen - Liquid Roofing System

Can you put bitumen on concrete?

Can Asphalt Be Laid Over Concrete? The short answer to this is yes.

What is a SBS system?

Styrene-Butadiene-Styrene (SBS) describes a family of synthetic rubber derived from styrene and butadiene. SBS is a thermo plastic elastomer that has an excellent abrasion resistance and aging stability when blended with bitumen, making it the perfect bitumen modifier to achieve cold flexibility and elastic properties.

What is bentonite waterproofing?

Bentonite waterproofing is an exterior waterproofing treatment that is supposed to work by forming a barrier between wet soil and the building foundation. Like any type of clay, bentonite absorbs moisture.

What is torch applied waterproofing membrane?

Torch-on membrane waterproofing is a type of building waterproofing solution composed of bitumen and a variety of modified polymers. When applied to the surface of a structure, it prevents moisture and liquid from seeping through — which when ignored, can negatively impact the integrity of a building over time.

What is PMMA waterproofing?

PMMA-Based Industrial Waterproofing Coating is a solvent-free, rapid-curing and highly flexible liquid applied membrane system. It delivers durable, long-term waterproofing and corrosion protection and is hard dry in just 60 minutes * (see Key Technical Data).

What is elastomeric membrane waterproofing?

Henry^® 787 Elastomeric Fluid Applied Waterproofing Membrane is a single component, cold-applied, rubberized asphalt emulsion which cures to provide a heavy duty “seamless,” rubber-like membrane for use in waterproofing or damp proofing concrete or masonry surfaces above and below grade.

What is liquid waterproofing membrane?

A liquid waterproofing membrane is essential for protecting many building structures. These flexible membranes are hand or spray applied onto surfaces such as balconies, podium decks and green roofs. They are even used to line municipal water tanks to prevent leaks.

What is cold membrane roofing?

Cold-process BUR uses solvent-based asphalt adhesives to adhere multiple layers of base sheet without heat. The membrane is then covered with aggregate. Once the waterproofing layer is in place, the membrane is covered with an aggregate surface or roof coating.

What is crystalline waterproofing?

Crystalline waterproofing is a process where the active ingredients in a crystalline product react with the free lime and moisture in the concrete to form crystals within the capillary system of the concrete.

What is fluid applied reinforced roofing?

Often referred to as spray applied roofing or spray on roofing because they are a liquid applied roofing membrane, Fluid Applied Reinforced Roofing Systems are thicker than paint and have elastic properties that allow it to stretch and return to the original shape without causing damage.

How long does torch on waterproofing last?

Torch On Waterproofing, also known as the torch-down roof, is one of the common roofing types used on flat roofs. When installed correctly, it can last from 15 to 20 years. This makes it a cost-effective roof for commercial businesses and the homeowner.

What is the best waterproofing for roof deck?

Polyurethane

Polyurethane is considered one of the best waterproofing materials. It can be applied seamlessly and penetrates the surface deeply and evenly. Thus, the polyurethane membrane will fill in even the finest cracks in concrete, reducing its water absorbency capacity.

Can you tile on top of torch on waterproofing?

The system is liquid applied that can be used with a fibrous membrane imbedded into the polyurethane system that can increase the life span of the product. It can be applied under tiles, allowing tiling directly over the system.

How long does bentonite waterproofing last?

In about 45 minutes, the Bentonite clay sets up resulting in a fairly solid, putty-like material. The Bentonite continues to expand for about the next 30 days as it forms a high-performance watertight membrane against the structure.

How many types of waterproofing are there?

The most common types of waterproofing are cementitious waterproofing, liquid waterproofing membrane, bituminous membrane, bituminous coating, and polyurethane liquid membrane.

Does bentonite swell when wet?

Clays, especially bentonite, have high affinities for water, distribute themselves evenly throughout water, swell when they become wet and the reverse when they become dry, and have electrically active surfaces and high specific charges (charge/mass).

What are the advantages of SBS system?

SBS rubber is flexible and has the memory to return to its original form. The addition of SBS rubber to asphalt increases the flow characteristics and improves the low-temperature flexibility and fatigue resistance of roofing asphalt. The end product is a high-performance, 2-3 ply system.

Is SBS the same as modified bitumen?

SBS modified bitumen roofing and APP modified bitumen are two very similar roofing materials. Both roofing materials are bitumen membrane roofing sheets made out of asphalt. However, the difference lies in the way the materials are modified.

How is SBS applied?

SBS is the most customizable of our low-slope commercial roofing products with glass, polyester and composite reinforcements. It can be installed with the widest variety of application methods including cold applied, heat weld, self-adhered, mechanically fastened, and hot applied applications.
