External Basement waterproofing system with Mineral sealing slurries.
Mineral sealing slurries are especially robust waterproofing systems with extremely good adhesion to mineral surfaces. They are not affected by moist surfaces and become an integral part of the building structure on which they are applied. They are paste-like and are applied seamlessly to the building element to be waterproofed. They are easy and safe to apply and can be installed as rigid or crack bridging systems.
On clean, solid, stable, gypsum free mineral substrates KÖSTER Polysil TG 500 is applied as a primer. This immobilizes salts present in the substrate and the substrate is solidified. Pipe and cable penetrations are either coated with the respective thick film sealant or fitted with flanges. The actual waterproofing is achieved using KÖSTER NB Elastic Grey or KÖSTER NB Elastic White in two layers. The installation of KÖSTER Flex Fabric is recommended between the KÖSTER NB Elastic layers to achieve an especially visco-plastic waterproofing layer.
In areas especially in danger of water creeping behind the waterproofing such as wall-floor junctions, a substrate preparation of KÖSTER NB 1 Grey mixed with KÖSTER NB 1 Flex should be applied. To avoid stresses in the elastic waterproofing, rounded fillets made of KÖSTER Repair Mortar are installed in interior corners.
Before backfilling, the waterproofing is protected from mechanical damages and settling with KÖSTER SD Protection and Drainage Sheet.
