Manhole repair

Sauereisen Manhole ChimneySeal No. F-88 is a chemical-resistant, elastomeric lining composed of a fiber-reinforced, asphalt-modified urethane. The lining prevents the inflow and infiltration of groundwater into the chimney section of manholes. It also accommodates horizontal and vertical movement of the substrate due to freeze/thaw cycles. It can significantly reduce the cost of treating additional sewage volume that originates as inflow through voids and cracks along manhole grade rings and chimneys.

Sherwin-Williams offers its Duraplate® UHS Ultra High Solids Epoxy with fluorescing Optically Active Pigments (OAP), allowing tank lining applicators to check the coating instantly for pinholes, holidays and other discontinuities and verify uniform coverage and proper film thickness. The new formulation is the only product of its type meeting the requirements of NSF Standard 61 for potable water tanks of at least 1,000 gallons. The coating uses Duraplate UHS Epoxy as the vehicle to hold the pigment, and is available as a single- or multi-coat application. A ‘civilian’ application developed from a technology supplied to the U.S. Navy, the fluorescing technology has doubled the service life of marine ballast storage tank coatings simply by illuminating insufficient film thickness wherever it occurs.
