Waterproofing Engineering Structures

Because the close contact with the surrounding grounds can lead to water infiltration of underground or partially-underground engineering structures, they need to be protected by setting up a good waterproofing system. A common method used by the waterproofing contractor in waterproofing engineering structures involves the application of waterproofing materials to the inner and outer walls of the structure. Together with the flooring, the waterproofing application creates a watertight seal that prevents the structure from coming into close contact with the ground, eliminating water permeation.

The waterproofing contractor installs the waterproofing system initially during building construction or later as a retrofit application for remedial waterproofing.

Aside from partial and complete underground engineering structures, there are external structures such as car parks, walkways, and loading decks that are exposed to constant traffic and mechanical damages caused by daily activities on the premises. The regular exposure gradually weakens the structure’s waterproofing system. This can lead to loss of slip- and skid-resistance, particularly in trafficked areas, and brings general deterioration to the structure.

The waterproofing contractor must have a high level of skill to waterproof engineering structures. Together with the facility owner, the waterproofing contractor must carefully design a waterproofing system that can handle the different ways that ground moisture can permeate the structure, and protect it from adverse effects.
