Protection Board is a pre-formed bituminous board modified with a special rigid compound. It is used to protect the waterproofing during backfilling procedures (retaining walls, fixed pavements, cast concrete, etc..) and construction traffic. Also available with mineral slate finish, used as a protective walkway to waterproofing layer on roofs. Protection Board is used also for refurbishment works, as a new supporting element (6 mm version), mechanically fixed.
