Concrete walls or hollow-block walls are not sufficient to ensure a full waterproofing and avoid leakage of a swimming pools. A full waterproofing system should be applied before putting the swimming pool in service.

Nature of problem:

Even if concrete is well made it will still need to be protected from “aggressive agents” that would otherwise accelerate deterioration of the element or structure and so reduce its durability over the years. Water from the ground, as with the water in a bath or pool, is naturally aggressive and, if it penetrates into the concrete, will weaken the structure.Marvel has a wide range of waterproofing products available to guarantee protection of the structure, as well as being waterproof.
