Two-component system
Structural engineering structures, such as viaducts, retaining walls and noise barriers, require specific and reliable protection against moisture infiltration and weather influences. For this purpose, Liquid Rubber offers high-quality sealing solutions that perfectly meet the technical requirements of these complex structures. The most commonly used products for this application are the Liquid Rubber SprayGrade and the BelowGrade, depending on the UV exposure of the surface.
Protect your architectural structures with Liquid Rubber's innovative and durable sealing systems.
For visible surfaces, we recommend using Liquid Rubber SprayGrade - a UV-resistant, two-component coating that seals seamlessly and flexibly and provides long-term resistance to sunlight, temperature fluctuations and soiling.
In non-visible applications, such as below ground level or behind cladding, the Liquid Rubber BelowGrade the right choice. This two-component system provides a robust, watertight barrier, without UV resistance, making it optimally suited for underground or covered applications.
Both products can be applied seamlessly with HVLP spraying equipment and offer long-lasting protection - even in the most challenging conditions.


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 is a 2-component system used exclusively by certified application partners can be applied. It forms a seamless, flexible membrane that is UV-resistant and therefore very suitable for outdoor applications.
