Our process for leak-sealing employs a special high density hydro-insensitive resin which is injected through small 5/8″ holes drilled directly through the concrete or metal wall parallel with the crack or break that requires sealing . As the resin mixture expands, voids are firstly filled and a controlled mold pressure is exerted. The aggressive nature of the POLY-MOR resin expands, fills and seals cracks in the retaining structure from the outside, inwards.

Although our resins are hydro-insensitive our application is limited to environments where “fast moving” water is not a condition since our resins are also liquid in form.

The composite material quickly cures to a strong, stable and long-lasting seal. Our process is particularly adaptable to manhole rehabilitation where water or wastewater infiltration or exfiltration is of concern. Water infiltration adds significant costs in water treatment and exfiltration may cause ground water contamination.
