Application

Oldroyd Xtf is typically applied as a tunnel waterproofing and cavity drain membrane as part of the Newton CDM System


Suitable Substrates:

  • Bare rock surface
  • Cast concrete walls
  • Vaults in escape routes
  • Technical rooms (or similar)
  • Link tunnels

Description

Oldroyd Xtf consists of a specially profiled, studded and grooved flame retardant polypropylene (PP) sheet, approximately 1 mm (40 mils) thick, onto which is laminated a high tensile strength, fire-resistant woven fabric of basaltic mineral fibres.


Whilst the polyolefin sheet provides the structure of the membrane and ensures its waterproofness, the basaltic fibre fabric increases its mechanical strength considerably, as well as being of vital importance to the fire resistance properties of the membrane.
