Waterproofing

MAR-FLEX 5000™ Waterproofing is a tested and proven membrane that can be applied over almost any clean, dry, sound substrate. Its permanent elasticity allows it to move with the structure. MAR-FLEX 5000 will not become brittle, evaporate, lose its flexibility, or lose its waterproofing ability. It resists freeze-thaw cycles and testing shows that MAR-FLEX 5000 outlasts conventional protection method. MAR-FLEX 5000 is available in both solvent based and water based.
