Diall extruded polystyrene foam aquastop underlay 5mm. pack of 5 pieces. bought for a bathroom flooring project but never got round to fitting. new & sealed condition but do have some storage marks on exposed sides. there is some inprints on both sides & very slight damage in photo no9. I dont think this would cause any problem when fitted as you could fit face down to floor so would be smooth on surface. please see photos before buying. posted via parcelforce 48hr. no click and collect at Argos due to size sorry.
