Making a casing

Casing is a radical way of getting rid of moisture. The idea is to create a "waterproof box" in the box that is the basement of your house.It allows you to take advantage of a cellar previously unusable, a basement or a garage entirely or partially buried.This treatment consists in applying a perfectly waterproof coating on the walls so as not to allow any more moisture to pass in. A casing radically removes all nuisances caused by humidity (saltpeter, black marks, etc.). The casing acts against lateral infiltration and offers a solution for all those who wish to renovate, enlarge and enhance easily and safely their real estate.This kind of work is exclusively informed professionals, able to offer you an extended warranty (10 years) The works presented here were made with Murpro 1 and 2 products, via Murprotec.

Necessary material

  • Masonry material
  • Professional equipment specific to the particularity of the construction site

A specialist (here at Murprotec) draws up an accurate diagnosis thanks to the data collected in the field: nature of the parts, hygrometric measurements, openings, ventilation, etc... His mission is to detect the related problems: lateral infiltrations, water supply, heating, ventilation, etc. In some serious cases, he will recommend the construction of a casing.

Stripping the walls of the cellar

Stripping the walls of the cellar

Exposure of the supports
Cement plasters, plasters and other wall coverings will be stripped first, to expose the substrate and the walls to be treated.

Drying of the cellar floor

Pumping the humidity of the cellar
A pumping of the infiltrated and flooded underground parts must be carried out in order to dry the soil before pouring a slab.

Laying of drains at the foot of the wall

Draining at the foot of the wall
A network of drains at the foot of the existing slab wall or gutter will eventually be set up to evacuate the lateral infiltration water.

Implementation of masonry

Realization of a slab screed with sump
A slab can now be cast and pulled. A sump is made here to cope with possible strong water flushes. One or more lift pumps are put into operation (this step is not systematic: it will be estimated according to the needs and the type of ground).

First treatment of lateral supports
A casing complex (here MURPRO 2) bicomponent resin (A + B) with epoxy aqueous dispersion and water-repellent cement is implemented in the form of a layer 12 to 18 mm thick on the buried wall parts and subject to lateral pressures or saltpeter outbreaks.
This complex has a back pressure resistance of 10 bar for 12 mm thick.

The white finishing coat (MURPRO 3 bi-component) is intended to waterproof the casing. It resists against back pressure, fungi and other micro-organisms and even meets the requirements of food contact.
