  • Manhole Chimney Seal

    Manhole ChimneySeal

    Manhole ChimneySeal F88 is an elastomeric lining used as a chemical-resistant membrane or gasket seal for the prevention of water infiltration. It maintains excellent elasticity and adhesion over a temperature range of -30°F to 250°F. The flexible barrier resists freeze/thaw stress. When subjected to mechanical stress, the lining has nearly 100 percent recovery. Manhole ChimneySeal also resists alkalis, salts, and acids.

  • Manhole SewerSeal


    SewerSeal is a water infiltration barrier for wastewater collection systems. It combines 100% calcium aluminate cement with finely graded inert aggregate for corrosion resistance to mild acids and alkalies. Seal and resurface deteriorated masonry and concrete structures. Moisture tolerance helps application in manholes, wet wells, lift stations, and pump stations. Exhibits high strength to withstand loads on underground infrastructure.
