Penetrating dampness can be caused by many different defects found in your Building, for example, poor or damaged roofing, broken gutters, blocked gutters, rotten window and door frames, defective pointing or render, and decayed brickwork, this allows moisture to penetrate the external parts of the building resulting in a damp interior.
The problem of lateral penetrating damp also exists, this occurs when the external ground level is higher than the damp proof course, basements, cellars, or plots built on sloping ground are often susceptible to this major problem.
.Remedial solutions for penetrating Damp:
Structural waterproofing or tanking is a system used to correct and stop water ingress through the structure of the building, as mentioned above when different ground levels compromise the exterior of a building, hydrostatic pressure is present and the ingress of water will occur. A tanking system is used to correct this, existing paints and plaster are removed from the walls and the substrate prepared for a cementitious compound which is applied to the area, by our expert technicians, this is done in conjunction with a chemical damp course applied above the exiting external ground level. Finished with a waterproof sand and cement system applied by our specialist technicians the results are a dry interior, fit for habitation.
This eliminates the need to dig out and lower the ground levels externally, solving problems of higher adjacent properties or higher ground levels.

Other methods used:
Where the ingress of water is at an unpredictable, much higher level, we use a membrane sealed system, allowing the water to flow to a designated point, it is then removed from the basement by means of a subfloor pump. The membrane system is also used above ground, giving an air gap to provide the protection required.
