From crack repairs, levelling screeds, concrete coatings and sealers to epoxy flooring, Total Waterproofing Solutions can assist.

As a result of shrinkage, structural or thermal movement concrete is prone to cracking in varying degrees of severity, from relatively inactive hairline flaws through to major faults and fractures, resulting in structural weaknesses, which greatly increase the risks of corrosion and ultimate failure.

The need for effective solutions for each category of faults is paramount to the long term durability and stability of the substrate. This is achieved through several repair methods such as:

Crack Injection

This method provides a non-disruptive solution by injecting epoxy or polyurethane resins in the void via a low-pressure injection system. Crack injection is also suitable for overhead, vertical and horizontal fractures and flaws.

Flexible Membranes

As opposed to the isolated repair method above, the use of a flexible liquid membrane provides a protective covering over the surface area encapsulating and protecting the substrate. These systems are in general used where a waterproofing solution is desired as a result of wide spread cracking.
