Waterproof Concrete

For sub-ground floor slab installation you must account for water seeping from the ground into the concrete. With a special waterproof concrete mix, we repel water under the slab to stop absorption.

In some instances, when installing ground floor concrete flooring, we always consider how ground water may affect the concrete. In every instance of installing a ground floor slab, we create a special mix of waterproof concrete which repels water by creating an impermeable solution.

Waterproof concrete is our method of choice for installing basements and sub-terrain concrete. It is a better solution than other tanking methods as there is less room for error in membranes that cannot be seen after the installation.

Waterproof Concrete Mix

We can create a water-resistant mix for new installations in order to repel water back into the ground, preventing any entry absorption into the concrete slab.

Waterproof Epoxy Solution

We apply a separate liquid epoxy solution to the top of a concrete slab to create an impermeable layer, keeping the concrete slab free of water damage.
