Bituminous membranes for non-roofing applications
Description
Bitumen (asphalt) based flat sections supplied in flexible rolled lengths. Asbestos may be contained in a layer of the bituminous roll or applied separately as a felt layer first with an asphaltic membrane covering.
Used for weather and water proofing.
Usually applied by rolling out the membrane onto a surface and applying heat (flame) to partially melt the compound and provide adhesion to the surface being applied to.
May be inserted into expansion joints.
