• Positive barrier to water and dampness with very low water absorption.
• Non invasive. Compatible with almost every waterproofing membrane and coating like: Bituminous, EPDM, TPO, PVC, polyurethane, butyl rubber, epoxy, acrylic, Chlorinated rubber, coal tar and many others.
• Withstands site abuse and impact from backfilling operations as well as effective protection against construction traffic, concreting and other topping work.
• Maintains shape stability at high temperatures and retains flexibility at low temperatures. It is tough, root-proof and non-bio degradable. It is unaffected by permanent immersion in water.
• Resistant to salts, chlorides and other chemicals normally found in soils.
• Can be used as a recovery board in re-roofing as a fast, light weight alternative to screed and eliminating the need to remove the old roofing regardless of its type.
• It comes in a variety of thickness from 3 mm to 6 mm.
• Semi-flexible can be bent to normal contours without cracking while rigid enough to hold as a board on vertical surfaces. • The top surface is covered with either fine sand (SAND) or a thin Polyethylene film (PBS). The bottom surface is covered with a thin easy torched Poly-Ethylene film.
• High puncture and impact resistance. Pass the chisel test.
