As PU hybrids, the MB PUReactive systems combine the best of several worlds, resulting in roof waterproofing with surprising capabilities. MB PUReactive systems are as economical as sheet waterproofing, but thanks to their excellent adhesion and flexibility, they are also ideal for use at junctions and material transitions.


It goes without saying that MB PUReactive systems fulfil the highest performance classes of EAD 0303-50-00-0402 (formerly ETAG 005).

What is PU hybrid waterproofing?

MB PUReactive is a PU hybrid waterproofing, but what does that actually mean?

The technology in MB PUReactive is based on a liquid component and a powder component that create a synergy when mixed together. Thanks to the straightforward 1 : 1 mixing ratio, mixing errors can be ruled out.The material has a long pot life of around 90 minutes once it has been mixed, but reacts rapidly once applied. This means that the waterproofing is rainproof after around 2 hours.

In most cases, there is no need for a primer, or else a contact layer of the material itself can be used

  • Unrivalled technical performance
  • Highly economical
  • Sustainable and up-to-date
