Waterproofing Membrane: Slab and Foundation

Leaking foundations can be the most critical of all the problems that can affect a building. Inadequate waterproofing above and below ground creates the greatest havoc.

External below ground tanking is widely agreed as the best method for waterproofing new and existing structures where possible. The main benefits of using exterior tanking systems are:

  • Keeps the walls of the structure dry
  • Extremely robust
  • Flexible and allows for movements over day joints
  • Easily repaired
  • Easy installation of service ducts through tanking

Remember concrete, masonry and many natural types of stone are inherently vulnerable to water penetration. So a positive tanking system is a robust, impervious, waterproof barrier between the outside face, (positive face) of the walls and their surrounding ground material.

Liquid Rubber Waterproof Membrane

Foundation waterproofing needs to be seamless, stretch over cracks and withstand hydrostatic pressure caused by heavy rains. In all climates variance in temperatures cause structures to expand and contract causing stress on weak areas of the structure and waterproofing membrane.

In addition to this thermal cycling other external factors can also affect the performance of the waterproofing membrane.

The majority of waterproofing membranes, irrespective of the method of sealing, create joints and seams which may succumb to splitting, cracks and perished seams allowing water to penetrate the building envelope.

Spray applied polymer-modified asphalt exterior foundation waterproofing stops water on the outside, before it enters the slab.

Liquid Rubber forms a totally seamless membrane even when formed around complicated shapes and services. This coupled with an elasticity of up to 1100% and
90 % memory (recovery) eliminates the problems caused by thermal cycling and most other external factors.

After completion the building will be secure from water ingress with a fully bonded, simple to maintain, seamless membrane capable of moving with the building during thermal cycling.
