POLYBIT Bituboard

Fibre impregnated asphaltic protection board

  • Weather, warp and rot proof
  • Compatible with most waterproofing systems
  • Non bio-degradable

Features and benefits

A multi layer, asphaltic protection board manufactured by thermally bonding polymer modified bitumen with selected additives which, sandwiched between a layer of saturated fibre-glass on one side and anti-stick polyethylene liner on the other.



POLYBIT® BITUBOARD has been designed for use as a permanent protection to most waterproofing and damp proofing systems, especially the bitumen based sheet membrane and coating systems. Bituboard will absorb the impact of aggregate shock, normal site foot traffic and protect the waterproofing membrane from penetration by the edges of reinforced steel and aggregate during the backfill process and late settlement.
Available pack size: 3.2mm, 3.5mm, 4mm & 6mm.

How to use


The application of Bituboard should be carried out when the ambient temperature is between 5°C and 55°C and should avoided in case of extreme weather conditions such as sand storms, rain, etc


Bituboard can be fixed on top of the waterproofing membrane by using a double sided adhesive tape (Bitutape TS)*, Bitubond N or even by torching (for fixing over torch applied membranes). Once the protection board is fixed in place, supports/props have to be used to keep the boards in place till the adhesive is strong enough to hold the board. Subsequent boards shallbe laid continuously by butt fitting the edges. 


For irregular profiles, the board shall be cut to fit all intersections and protrusions.The butt joints can be sealed with 50mm wide HDPE bitumen adhesive strip to prevent any backfill material entering and causing damage to the underlying waterproofing membrane.
