  • Reinforced waterproofing system for porous decks
    Patent number: 5979133
    Abstract: A composite reinforced roof is formed by applying to a roof deck a preformed membrane which has a tacky lower layer formed from rubberized asphalt. The second layer of the preformed membrane is a reinforcing mesh material embedded in the surface of the rubberized asphalt. This is applied to a roof deck and subsequently overcoated with a molten coating of rubberized asphalt. The self-adherent rubberized asphalt membrane prevents formation of bubbles and pinholes in the molten rubberized asphalt layer. This is particularly beneficial when the roof deck surface is lightweight structural concrete which releases gas when heated.
