is a multi-ply semi-rigid core composed for mineral-fortified asphaltic core formed
between two outside layers of asphalt-impregnated fiberglass mat, which are weather-coated
and covered with a polyethylene anti-stick sheet. When properly applied by work personnel
trained in good waterproofing techniques, Protection Course will absorb the impact of
aggregate shock and normal jobsite foot traffic. It also protects the membrane
waterproofing from penetration by sharp aggregate during backfilling and later settlement.
Protection course is available in three types; PC-1, Light Duty; PC-2, Standard Duty and
PC-3, Heavy Duty. All three types are economical and convenient to use.
Protection Course is used in between-slab construction, such as plaza decks, roof
terraces, promenade decks, pedestrian concourses, tunnels, floors of bathrooms, shower,
kitchens and mechanical rooms, parking garage decks, planter boxes, reflective pools and
foundation walls. Protection Course is compatible with most currently popular dampproofing
and water proofing materials.
