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 URETEK resin expands, fills and seals cracks in the retaining structure from the outside, inwards.
Although the resins are hydro-insensitive the application is limited to environments where “fast-moving” water is not a condition since the 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.
