Membrane protection board


Corroboard is a multi layer, semi rigid protection board composed of a mineral enhanced asphalt core between an asphalt saturated fibre glass mat, protected by a weatherproof polyethylene carrier film that provides a tough, lightweight, durable, waterproof and non degradable board, for the protection of waterproofing membranes.

Corroboard is easy to handle, can be used both horizontally and vertically, and is available in thicknesses of 3.2, 3.5 or 6 mm.


Corroboard is typically used to protect both liquid applied and sheet waterproofing membranes against impact damage from site activities and coarse or sharp materials during backfilling.
