How it works
Ordinary concrete contains fine pores which allow moisture to penetrate the surface and pass through. The size and volume of these pores is dictated by the water/cement ratio; the higher the ratio, the more porous the concrete. TopProof's pores are filled to create a high density ensuring a watertight concrete.
Quick and easy to lay
TopProof is laid in exactly the same way as ordinary concrete so no special skills or equipment are required. Should you require any help all you have to do is ask, Tarmac offers full training and professional on-site support.
Cost effective to use
Impermeability is built-in, so there’s no need for external membranes or any of the hassle that goes with them. As a result both material and labour costs are significantly reduced.
Less risk of cracking
TopProof is less susceptible to early age and drying shrinkage cracks, which are both common problems when external membranes are applied.
Better for the environment
TopProof eliminates the need for oil based chemicals and synthetic materials, greatly reduces waste on site, cuts vehicle movements and is 100% recyclable.
Easy to maintain
Minimal maintenance is required and should any problems ever occur they can be easily identified and quickly repaired.
