W - Waterproofing systems - Basement, tank, and area waterproofing

Wet basements may not be fully usable and might endanger the building foundation. We offer different methods to permanently waterproof basements: From the exterior with polymer-modified thick film sealants, mineral sealing slurries, or cold self-adhesive waterproofing membranes, which treat the entire external wall area and protect from water penetration. In repair cases, the waterproofing can be installed from the inside of the basement. This method is called “curtain injection”.

In a repair situation the basement can be waterproofed from the inside without excavating the soil around the building. This means that the basement is permanently waterproofed without the necessity of doing any sort of earthwork. This type of waterproofing is possible with the KOSTER systems even when the wall has active leaks. Subsequently an open-diffusion restoration plaster is applied after successful waterproofing.

This field poses the highest demands on waterproofing. It must be able to resist the weather, be waterproof and provide a certain structural stability. Also, outside the movements of the construction members are usually comparably large so that it is necessary to use waterproofing systems with high crack bridging capabilities.

Leaking sewage pipes in wastewater treatment plants lead to considerable damage which is often discovered very late. When restoring such damage it is important to mitigate the different types of damages with waterproofing systems which are specifically adapted to the need. The damage analysis reveals if locally limited waterproofing of the leakage is sufficient or if the entire area has to be protected from chemical attack.
