Water can be destructive to a building which is why it's important to keep it out. APOC sells below grade products that feature 60 millimeter sheet waterproofing. Our water based, elastomeric products can be applied to further waterproof the membrane. Protection board and bridge deck planks further ensure water tightness. ASTM emulsion dampproofing is offered in spray, brush and trowel grades. Ask about our above grade air barriers and vapor barriers too!
