POTENTIAL CAUSES OF THE PROBLEM

a) Waterproofing Failure
b) Lack of waterproofing

SOLUTION

Carefully examine concrete walls of the basement. In case of an existing leakage, we should use WRM 500, a non shrinking, fast-setting, one-component repairing mortar.

For the preparation of WRM 500 only water is needed. In a clean pot add 210 – 230 ml of water and gradually add 1 kg of WRM 500, stirring continuously with fast and strong moves, with a spatula, in order to create a homogeneous maze.

Having worn protective gloves, shape the mixture and put it on the hole.

Press gently for 3 minutes, until the mixture stabilizes completely.
