bituboard polybiy, brand : polybit, made in UAE
Bituboard is a multi layer, asphaltic protection board. It is manufactured by thermally bonding polymer modified bitumen with selected additives which is then sandwiched between a layer of saturated fibre-glass on one side and anti-stick polyethylene liner on the other.
Field of Application
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 indicated in BS 8102. 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.
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 (Watertite TS 15)*, 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 shall be 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
Bituboard is shrink-wrapped and loaded on pallets for easyhandling. The pallets should be loaded or offloaded with the help of a crane or forklift to prevent damage to the protection boards. If the boards are unloaded individually, it is to be ensured that they are stacked back on a pallet or on a flat surface
Storage & Shelf Life
Bituboard should be covered and stored in a dry and shaded area away from sunlight, UV and sources of
heat. Do not stack one pallet on top of the other. It is recommended not to open the shrink wrap till the time of application. The boards, loose or on pallets, must be stored on flat surface. The shelf life is 12 months when stored as per the recommendations. Excessive exposure to sunlight and UV will result in the deterioration of the quality of the product and reduce its shelf life
