Nuraprufe 415 (LTA Approved)

Nuraprufe 415 membranes are applied horizontally to prepared lean concrete or well rolled and compacted sand or crushed stone blinding. 

Vertically the membrane is fastened to permanent formwork or adjoining structures.

Concrete is then cast directly against the adhesive side of the membranes. The specially developed pressure sensitive adhesives work to bond the membrane to concrete face.

The Nuraprufe System includes:

  • Nuraprufe 415: A high performance HDPE membrane
  • Nuraprufe 415 (Self-Adhesive): A self adhesive HDPE membrane for external wall application
  • Nuraprufe Tape for lapping between two rolls of membrane
