Waterproof protection of concrete decks with Liquid Rubber

Concrete decks are exposed to heavy loads from traffic, water, de-icing salts and temperature fluctuations on a daily basis. Without adequate protection, cracks, leaks and corrosion of the reinforcement occur.

Liquid Rubber forms a durable, seamless and fully waterproof barrier that provides long-term protection of the concrete against penetration by water, salts and chemicals.

Final protection against overlying moisture

For concrete decks that remain visible or outdoors, it is Liquid Rubber SprayGrade the right choice. This two-component system is UV-resistant and can be applied quickly and efficiently with our HVLP pump system - ideal for larger areas.

If the concrete deck is built on or provided with a roof garden after application, we recommend using Liquid Rubber BelowGrade. This also two-component system is specially developed for applications without UV exposure and provides long-term protection against rising damp and water penetration.

Both systems adhere excellently to a variety of substrates and form an impermeable, permanently flexible barrier after curing.

Why professionals choose Liquid Rubber

Your benefits with Liquid Rubber products

Both Liquid Rubber SprayGrade and Liquid Rubber BelowGrade are permanently elastic and together form a completely seamless seal without seams or weak spots.
Liquid Rubber BelowGrade and SprayGrade

Liquid Rubber BelowGrade

Liquid Rubber BelowGrade is a 2-component system used exclusively by certified application partners can be applied. The product is not UV-resistant and is therefore applied to areas where no exposure to sunlight occurs - for example, below ground level or in applications on the inside of buildings.

Liquid Rubber BelowGrade is highly elastic, vapour-proof, air- and watertight and adheres to virtually any substrate, making it a reliable solution for connections and transitions even under the harshest conditions.

Liquid Rubber SprayGrade

Liquid Rubber SprayGrade is a 2-component system that is always applied by trained application partners using special spray equipment. It forms a seamless, flexible membrane that is UV-resistant and therefore very suitable for outdoor applications.

Like the other products, Liquid Rubber SprayGrade is highly elastic, vapour-tight, air- and watertight and has strong adhesion to a variety of substrates, thus providing a durable seal even for complex details and transitions.
