TREMproof® 6145 is a hot-applied rubberized asphalt membrane for use in waterproofing underneath traffic-bearing asphalt and concrete overlays. The formulation of TREMproof 6145 offers an optimum balance of rubbers, asphalt and inert fillers to give it the robust properties required at a lesser mil thickness for applications under asphalt where the exposure to sheer stresses may be much greater than on standard plaza deck applications. This decreased mil thickness makes it an economically feasible option for such applications.
