Liquid waterproofing
Liquid waterproofing systems are cold-applied liquid membranes that can provide long-term protection for external flat and sloped surfaces. They can provide a seamless finish that will protect the surface for years to come. It can be applied by hand or sprayed onto surfaces like balconies and podium decks.
Liquid waterproofing information
With over 120 years of experience and a highly trained team, we can provide you with the best possible guidance when it comes to choosing the right liquid waterproofing systems.
Liquid waterproofing is waterproofing that does not have any cementitious components and can be either a single- or two-part mix.
This is the most common type of waterproofing product. It is easy to apply, generally has no pot life limits, and is often cheaper than cementitious waterproofing products.
Liquid waterproofing products are often classified as Class 3 membranes, which means they have an elongation of greater than 300%. The technical data sheet that we supply with each product provides this information.
There are several types of liquid membranes available. Each has unique features that make it suitable for particular applications. The different types include Latex, Acrylic, Acrylic/Urethane blends, and moisture-cured polyurethane.
