PU-MEMBRANE

Urethane waterproofing membrane

PU-MEMBRANE is a solvent less, two component urethane waterproofing membrane. It is designed to be used as a layer to bridge new cracks in concrete. It exhibits very good mechanical properties, such as high elongation and tear resistance.

Advantages

  • Economical and easy to apply
  • Highly resistant waterproof elastomer
  • Solvent-free, low odor and fast curing for accelerated turnaround
  • Pre-measured packaging

Technical Data

IMPORTANT NOTE: PROPERTIES @ 73°F (23 °C) and 50% R.H. Times are approximate and will be affected by changing ambient conditions, especially changes in temperature and relative humidity. The indicated mileage is calculated for flat surfaces. A porous or imperfect surface will require more material in order to cover the same mileage. *
