This semi flexible board is a convenient way to ensure adequate protection to waterproofing membranes
against damage caused by site traffic, mechanical damage and ground settlement.
Made from a mixture of fibres saturated with at least 75% bitumen, Wallbarn Bituminous Protecto-board is completely waterproof and provides superior impact and abrasion resistance.
It is covered both sides by a polythene film, meaning it can be used on surfaces not normally compatible with bitumen. The film avoids the bitumen bleeding onto other surfaces or the boards sticking together during storage.
Our Bituminous Protecto-boards are ideal for vertical applications. They can also be heated with a blow torch and fixed to the substrate – the bitumen softening temporarily and bonding to it – so that the entire surface of the Protecto-board is
By being bonded there is no risk of water, dust or other particles passing through the joints and onto the membrane beneath.
It can be easily cut using a sharp knife and shaped around particular corners and details. This is very useful for protecting membranes around things such as outlets and upstands.
Wallbarn Bituminous Protecto-board is also fixed by butting the joints together and securing with a spot bond adhesive (on verticals) or taping over the joints with a strong double sided bitumen tape (for horizontal decks).
This is useful for temporary protection, where areas need to be guarded against following trades, and the boards taken up at a later date if required.
These boards are completely waterproof and rot proof. They can be immersed in water without risk of delaminating or compromising their performance.
We supply Wallbarn Bituminous Protecto-board in pallets of 200 sheets as standard. It is recommended
that they are stored out of direct sunlight and they are not compatible with hot membranes at temperatures above 150ºC.
Wallbarn protecto-board is available as a bituminous membrane, for use as a protection against damage to waterproofing.
