Damage in existing buildings is often caused by leaking pile foundations. Water can enter the building through the construction joints or it makes its way along the reinforcement steel. The waterproofing of pile heads has to withstand heavy loads from the whole building and it 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 reprofiled with KÖSTER Repair Mortar or KÖSTER Repair Mortar R4. This reprofiling must also include the installation of a fillet adjacent to the pile head. KÖSTER NB 1 Grey is used to waterproof the top of the pile head.

Mineral corrosion protection for the steel reinforcement bars is carried out with a first layer of the polymer modified special slurry KÖSTER Z 1 and a second layer of KÖSTER Z 2. KÖSTER Z 2 is red pigmented and allows a visual control of the application.

The waterproofing on top of the blinding layer is made with KÖSTER KSK SY 15. KÖSTER KBE Liquid Film is applied as primer on the entire surface as well as on all overlaps around the pile head. Protect the waterproofing layer from mechanical damage when continuing with the application.

Always adhere to the specifications in the respective Technical Guidelines.
