TOPPROOF WATERPROOF CONCRETE

TopProof offers a simple, cost effective alternative to traditional watertight construction methods.

There’s no need for additional finishes or external membranes, so it’s very quick and easy to install. It’s also highly reliable, requires minimal maintenance and it will not leak.

Ordinary concrete contains fine pores that 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 waterproof concrete contains two specially formulated admixtures. The first reduces the water/cement ratio, increasing the density of the mix and minimising the size of the pores. The second fills the remaining pores ensuring a completely watertight finish. This means there is no need for external membranes, reducing cost and labour.

Benefits

  1. 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.

  2. 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.
  3. 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.
  4. Quality assured

    Tarmac delivers quality products through a thorough understanding of customer needs and operates best practice in quality management systems which conform to ISO 9001.

  5. Easy to maintain

    Minimal maintenance is required and should any problems ever occur they can be easily identified and quickly repaired.
  6. 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.
  7. Responsibly sourced

    We have been awarded a BES 6001 rating of VERY GOOD across all of its product ranges including ready mixed concrete. No other company has achieved a higher rating across so many product groups

How it works?

What the difference between TopProof waterproof concrete and conventional concrete?

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 high density ensuring a watertight concrete.

What's unique about TopProof waterproof concrete?

Tarmac TopProof waterproof concrete is better for the environment compared to conventional methods of waterproofing. This is because many membranes contain oil-based chemicals and synthetic materials.
