3. Stresses to which waterproof coatings are subjected
3.1 Cracks, substrate movement
There are many causes of cracking in concrete:
variations in the dimensions of the support due to mechanical causes, e.g. excessive deformation of the structure as a result of differential settlement of the soil, operating loads, etc. ;
shrinkage, which leads to cracks when the concrete dries;
concrete creep (slow deformation over several years...
