Bituminous Felt Membrane


Bituminous felt is waterproof sheeting used for surfacing roofs or as an underlay beneath tiles or slates.

Bituminous or Bitumen Felt is made from bitumen, a tar-like substance derived during distillation of crude oil, mixed with sand or crushed limestone, and applied to a fibrous membrane made from such materials as hessian, fibre-glass, polyester or paper. The felt may be finished with a coating of sand or fine gravel to give a decorative finish.

Bituminous felt is a cost-effective and convenient way of providing waterproof covering to roofs. It is widely used on flat roofs, as well as on sheds and similar garden buildings.
