FUSION SB’s remarkable properties are the result of a cutting-edge production process that uses 100% virgin polymer, meaning the polymer within our FUSION SB membrane has never been used in another product. Using newly created polymer improves FUSION SB’s effectiveness and product uniformity versus recycled polymer membranes. This premium waterproofing product resists acid rain, salt spray, freeze-thaw cycles and all types of weathering.
FUSION SB waterproofing membrane can be applied to any below-grade poured foundation basement wall as a waterproofing membrane. FUSION SB membranes can also be used for brick flashing when applied to concrete walls with vertical ledges or as an exterior above grade air/vapor barrier for cavity walls. FUSION SB is solvent-based, sprays easily and produces a flexible and seamless seal.
Although FUSION SB is an incredibly strong waterproofing membrane, it is still more effective as a component of a waterproofing system. Pairing FUSION SB with an approved Mar-flex drainage board extends the membrane’s warranty from 15 years to “limited lifetime.” Use the chart below to determine your ideal level of protection.
