Waterproofing Concrete and Brick in Underground Structures

Underground and foundation structures are vulnerable constructions when it comes to damp and water leakage. Usually there is no sealing membrane to prevent damp and water from penetrating the concrete. In which case it is necessary to waterproof the concrete to prevent damaged caused by damp.

Protection against penetrating moisture and leaks

Basements, mat-slabs, semi-basement houses, crawl spaces and suspended foundations can all suffer from problems caused by external moisture. In most cases, these problems can easily be remedied with Innerseal waterproofing. Innerseal prevents water from penetrating the structure and allows the concrete to breathe at the same time. Application can be done both externally and internally. Some structures are built using more porous materials, that may need supplementary measures like drainage, membrane or injection. Therefore, we always carry out a thorough examination of what is causing the problem before we can propose a solution.

Prevent damage caused by damp

Innerseal is a concrete waterproofing that also can be used for preventive purposes, to protect a mat-slab and concrete floors against water leakage from internal installations and utilities. Should there be defects in the sealing membrane, the waterproofed concrete will not absorb water in the event of a leak. Recovering from a water damage, which normally takes several months, will only take a couple of days. If there is no moisture barrier under the mat-slab or the basement floor, it is not possible to cover the surface with a watertight layer like paint or plastic flooring. Ground moisture penetrates the concrete in vapour form and condenses into water under the paint or glued flooring, which loses its adhesion from the substrate. By waterproofing the concrete floor, it is possible to obtain a dry abrasion resistant floor that breathes and is easy to clean. If one do not wish a gray concrete floor, the Innerseal Plus(+) surface protection can be dyed using the Ameripolish colour system (25 different colours).
