- Step By Step
Application
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)* 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 HDPE bitumen adhesive strip to prevent any backfill material entering and causing damage to the underlying waterproofing membrane.
