Rehabilitative waterproofing

26 Sep Rehabilitative waterproofing

Many structures, especially in developing countries, have been built with flaws in their sealing systems. The passing of water through the structural system during the operational period can lead to a catastrophic event and is always a problem. Different techniques can be used to stop the water ingress in an appropriate efficient and cost effective engineering system. Some of the fundamental methods for rehabilitative waterproofing can be summarized as follows:

• Installation of waterproof concrete
• Installing waterproof layers on the upstream surface
• Application of crystalline forming material
• Joint filling
• Injection

A good understanding of the current geotechnical and geo-hydrological situation of the surroundings and a good perception of the current condition of structures are vital for the successful implementation of rehabilitative waterproofing methods. Windavar, along with its international partners, has gathered a valuable know-how about these kind of projects which can be used to provide project specific solutions to such problems.
