Root Barrier Lapping Tape
Root Barrier Lapping Tape is a self-adhesive sheet membrane constructed from an oriented cross laminated high density polyethylene sheeting and a bitumen-polymer adhesive compound. The product is a tough, durable, self-adhesive sheet with an overall thickness of 1.5 mm.
Uses include waterproofing foundation, basements, roofs and plaza decks, lift shafts, pits, service reservoir roofs, car park decks and subways
Supply The joining tape is supplied in cardboard boxes, each box bearing the roll type and manufacturing batch code.
Storage Boxes must be stored vertical on end, in dry conditions out of direct sunlight. Storage temperature should be between 5°C and 30°C.
Preparation Ensure surfaces are smooth, clean and dry.
Application Ensure that air temperature is greater than 5°C. Remove the release paper as the sheet is laid, and firmly press the membrane down as it is applied to avoid entrapped air.
When sealing root barrier overlaps apply the joining tape centrally along the lap on the side facing the tree ensuring the surface is clean and dry.
Protection Care should be taken to avoid damage to the joining tape during backfill operations.
