Bauder AP3 Protection Board is a lightweight, pre-fabricated board made from a mixture of fibres saturated with at least 75% bitumen. It provides impact and abrasion resistance whilst protecting the waterproofing system. It is ideal for horizontal and vertical applications. Both sides of the product are smooth-surfaced and covered with a polyethylene film. Modified bitumen membranes can be torched, mopped or applied in cold adhesive directly to the board.

Bauder AP3 Protection Board is used for temporary or permanent protection over waterproofing applications on parking garage decks, roadways, terraces, planters, green roofs, and promenade decks. Permanent protection to horizontal and vertical waterproofing membranes against damage caused by site traffic, mechanical damage and ground settlement. 

Temporary protection to areas which need to be protected against following trades; the boards can be taken up at a later stage if required.
