Damp proofing is used in the production of modern homes and buildings. It is an compulsory application to the foundation structure to put a stop to damp increasing and filtering through the walls of the building into the inner spaces.

Damp Proof Methods
There are a range of methods which can be used of which the laying of a horizontal barrier at foundation wall level is perhaps the most used. A membrane is used to build a hard surface through which damp cannot breakthrough. If not done correctly, water rises from the ground through the building walls and causes damage to the structure in the form of cracks, paint chipping, and spots on the wall surface. The membrane basically acts as a barrier.
Diagnosing Wronfully
More often than not, paint chipping and condensation problems are attributed to rising damp. Only in excessive cases can such be accurate. If a membrane was properly applied when the building was erected as part of damp proofing, there should not have been a problem. Other factors that can share condensation problems include that of improper application of cement to the outside walls and usage of inferior plaster material in the interior.
Damp proofing should be finished upon erection of a structure to repel salt from the ground to be absorbed in the walls. The membrane used in the procedure can consist of any of the following resources:
- Bitumen
- Plastic sheets
- Stones
- Asphalt
Plastic is the preferred material for damp proofing. It is a strip that is laid between two layers of bricks at ground level. The plastic is normally made from polythene and can also be laid underneath a solid floor slab.
If a building has no damp proofing membrane remedial work may be needed to prevent further structural damage and health problems associated with the dampness. Holes can be drilled into the walls and silicone used to fill the holes. Another method is to apply damp proof substances. Yet, a further method involves the transfusion of a silicone based substance. It is essential to avoid the usage of asbestos or lead based damp proof materials.
Waterproofing Roofs
The roof of the structure must be waterproofed successfully to put off leaks and collapsing of the roof due to water build-up and structural damage. South Africa has a versatile climate. As warm as it can get, it is also a country known for storms and long periods of soft rain, making it vital to revamp any roof damage abruptly. Before attempting to do the water proofing, get an expert in as mistakes made can be costly, apart from the danger of working on the roof.
Damp and Waterproofing for Roofs
There are many methods that can be used to deflect leaks. Liquid sealants are among the most shared applications. Rubber or plastic coatings can also be applied everywhere the roof has a concrete slab. The plastic or rubber is flexible and can move along with the concrete.
Tar shingles are also used as one of the methods. It is imperative to first fix any crooked shingles. Synthetic applications can be used in the case of flat roofs where you don’t want gravel to be used on the roof. Gravel in many instances hinders the identification of leaks and as such is a method rarely used. If there are only little isolated leaks the experts will apply a silicon-based substance to seal the leaks. Make certain approved water and damp proofing by making use of a trusted company.
