Xtra-Load Protection Board is a pre-moulded tough durable material used as a protection for waterproofing membranes against backfill for below ground walls.
Xtra-Load Protection Board withstands normal on site foot traffic protecting the membrane from construction abuse and puncture by rock and aggregate during backfilling operations.
Xtra-Load protection Board is not intended as a water proofing material though it has water proofing qualities.
