Insensitive to temperature changes
Tunnels are constantly exposed to groundwater, temperature fluctuations and other extreme environmental influences. Reliable waterproof protection is therefore essential for both structural safety and infrastructure longevity. For these applications, Liquid Rubber offers the ideal solution: BelowGrade.
Extend the life of your tunnel structures and contribute to sustainable infrastructure with Liquid Rubber's reliable and environmentally friendly sealing systems.
The two-component system of Liquid Rubber BelowGrade has been specially developed for below-ground level applications, such as tunnels and subways. The product forms a seamless, permanently flexible barrier that adheres effortlessly to concrete and other common building materials - even on complex shapes and details.
Liquid Rubber BelowGrade contains no toxic substances, making it ideally suited for projects where a park, roof garden or natural environment will be built on top after finishing. Flora and fauna remain fully protected, without compromising environmental quality.

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.
