Why use Collect concrete?

Additional info

Concrete is naturally porous due to its capillaries forming migratory paths for water to pass through. This porosity can be reduced by adding special active components which block these capillaries, effectively sealing the concrete permanently against the penetration of water and harmful chemicals. Topproof waterproof concrete is designed to meet the requirements of waterproofing as defined in BS8102 (all grades).

The use of specifically tailored admixtures provides TopProof watertight concrete with structurally integral waterproofing. This enables concrete to be poured and compacted with ease in comparison to barrier type products or membranes which function only at the surface of the concrete.
