KÖSTER Thermoplastic Membranes are applicable for a wide variety of substrates and fields of application. As foundation waterproofing, they excel by their speed of application, durability, instant waterproofing effect, and can be backfilled immediately.
KÖSTER Membranes consist of thermoplastic polyolefin, produced in Germany with the highest quality compounds and standards. KÖSTER Membranes conform to DIN EN 13967:2012 and are rated as Type T moisture barriers. They provide high elongation and are highly tear resistant so that even large cracks are bridged securely. KÖSTER Membranes are free of PVC as well as plasticizers and are age and root resistant. As they can withstand high mechanical influences and stresses, they are the perfect protection for underground structures.
To ensure a watertight installation and long service life, the KÖSTER membrane seams are welded homogeneously with hot air, using a special hot air welding machine. A signal layer shows any mechanical damage that can be repaired quickly and easily.
Before backfilling the waterproofing is protected from mechanical damage and settling with KÖSTER SD Protection and Drainage Sheet.
Always adhere to the specifications in the respective Technical Data Sheets.
