A 2mm corrugated polypropylene protection board, 1805mm x 1210mm, laid over waterproofing membranes before backfill, screeds, or other trades get on site. It takes the impact and puncture load so the membrane underneath does not.
Light enough to carry and cut with a knife, tough enough to survive a build. Tape the joints so sheets do not shift, and leave it down until the surface work starts.
2 mm corrugated polypropylene protection board for shielding cured waterproofing membranes during backfilling, screeding and following trades.
Lightweight sheets are easy to carry, trim and position over the finished membrane.
Allow the waterproofing membrane to cure as specified by its manufacturer.
Lay the Corflute board over the membrane and trim around corners and penetrations with a suitable knife.
Butt or slightly overlap sheets and tape joints where needed to stop movement.
Keep the protection in place through the following construction activity.
Protection layer only; not a waterproofing membrane or structural load-bearing board.
Install only after the underlying membrane has reached the cure or set condition required by its manufacturer.
Protect from excessive heat and prolonged direct sunlight.
