We can now offer the new Wallbarn Bituminous Protecto-board, a strong, semi flexible multilayer bituminous protection board for use as a temporary or permanent protection layer to waterproofing.
Wallbarn Bituminous Protecto-board consists of layers of roofing felt saturated with bitumen and reinforced with glass and polyester fibre, providing a superior resistance while maintaining a sufficient degree of flexibility for normal site usage. One side is covered with an anti-stick polyethylene film.
It is very light, tough and easy to install. Because it has one side covered in film, it can be laid against surfaces not normally compatible with bituminous membranes.
Wallbarn Bituminous Protecto-board is ideal for installation onto vertical surfaces. The exposed bituminous side can be heated and stuck to the vertical surface very easily, providing an excellent bond before backfilling..
These boards have a great deal of strength and durability. They can tolerate heavy construction traffic on horizontal surfaces;
and on vertical applications have high resistance to ground settlement, concrete pour and mechanical damage during backfilling.
It can be easily cut with a sharp knife and shaped around particular details.
The boards can be butted together and sealed at the edges with bituminous tape, if required.

Advantages of Wallbarn Bituminous Protecto-board
Withstands normal construction abuse and impact from backfilling.
Protection against traffic, concreting and other topping works.
Rotproof – unaffected by permanent or periodic immersion in ground water.
Resistant to salts, chlorides and other chemicals normally found in soil.
Impermeable to water and low vapour transmission – enhances water tightness.
Semi-flexible. Can be bent to normal contours while maintaining rigidity.
Stable at high temperatures while retaining flexibility at low temperatures.
Can be applied using adhesive or with a torch.
