Pile head waterproofing system.
Damage in existing buildings is often caused by leaking pile foundations. Water can enter the building through the construction joints or make its way along the reinforcement steel. The waterproofing of pile heads has to withstand heavy loads from the whole building and needs be easily connected to the area waterproofing. At first, all non load bearing materials and separating substances have to be removed from the surface of the pile head. After that, the surface has to be levelled and re-profiled with KÖSTER Repair Mortar Plus.
This re-profiling must also include the installation of a fillet adjacent to the pile head. KÖSTER NB 1 Grey is used to waterproof the pile head. The waterproofing on top of the blinding layer is made with KÖSTER Deuxan 2C. Embed KÖSTER Glass Fibre Mesh into the fresh first layer. Before pouring the concrete for the floor slab a gliding layer consisting of two layers of customary PE-Foil is applied between the waterproofing and the concrete. Protect the waterproofing layer from mechanical damage when continuing with the application.
