We've Got You Covered

Prokol MonoSeal is a liquid waterproofing membrane manufactured in the Netherlands. It comes in tins, and is applied as a cold liquid to the deck surface. As it cures it forms a highly waterproof covering. It is highly durable and long lasting. It remains flexible, no matter what the temperature.

MonoSeal can be applied with a roller, a brush or just poured onto a surface. Its hydrophobic, meaning it remains completely unaffected by contact to water. Most roofing products are hydrophilic, meaning water will gradually degrade them over time. It is UV resistant too, and vapour permeable, meaning moisture underneath can gradually evaporate.

Prokol Monoseal can be applied to an existing felt roof, as long as its sound, as well as concrete, brickwork, asbestos concrete and insulation boards. Its versatility means it can be applied at any time of year, and at any temperature. It will cure in cold conditions, as well as hot conditions. Its also safe to use, giving off no VOC’s.

Flat roofs are the obvious choice for MonoSeal, but it can also be used on sloping and pitched roofs, as well as walkways, as long as an anti-slip coating is applied.

Network Rail, Transport for London, London Underground and the NHS specify Prokol MonoSeal as their preferred product, and many local authority councils use it throughout the UK

​Clearly, it’s a very good product, and we highly recommend it.
