For extra-tough applications underground

Dirt, chemicals and bacteria found in sewage systems cannot damage our 804/814 Brunnen Schaum. This foam was specially developed for bonding sewer manholes and domestic sewage treatment plants. Naturally, it is also resistant to fresh and sea water as well as acids and alkalis. In shaft, well and civil engineering, the foaming adhesive impresses with its excellent adhesion to concrete elements. Fully cured, 804/814 Brunnen Schaum becomes semi-hard and predominantly closed-cell. What’s more, the product can withstand temperatures ranging from -40°C to +80°C.
