Leak Sealing
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.
Key Benefits
- Poly-Mor material is guaranteed for a period of 10 years against any significant deterioration.
- The aggressive nature of Poly-Mor resins ensures superior sealing qualities.
- The closed cell nature of Poly-Mor material is unaffected by freeze-thaw cycling.
- Poly-Mor material is environmentally friendly.
- Extremely clean process.
- Poly-Mor resins are impervious to water and other liquids.
- Poly-Mor resins are highly insulative.
- No excavations are required to treat the leaks — Non-Intrusive.
- With Poly-Mor Technology, it is possible to seal an extremely broad range of leak conditions, even if you are confronted with a water leak!
Commercial
Leak Sealing
Poly-Mor Canada is the industry leader in polyurethane foam solutions for large-scale commercial, industrial and infrastructure problems. Poly-Mor’s polyurethane foam injection is a fast, effective and minimally invasive method of repairing leaks in pipe joints. The hydro-insensitive and hydrophobic nature of our polyurethane foam stabilizes soils, displaces water, fills voids and seals joints and cracks. This is a cost-effective method to solve multiple issues common in water infrastructure projects in a single application. Our experienced personnel can attack the problem from both inside our outside the pipe, depending on the site conditions and accessibility.”
Applications
- Earth dam sealing
- Pools
- Leaking secant walls
- Basement walls and below grade parkades
Industrial
Leak Sealing
Poly-Mor Canada’s polyurethane foam injection system produces a fast and effective way to repair a variety of issues that cause sanitary and stormwater pipes to leak. In one application, the polyurethane simultaneously fills voids, densifies soils, and seals leaking joints and cracks. The polyurethane can be injected from within the pipe or from the surface depending on accessibility and pipe diameter.
When polyurethane is injected in a vertical and horizontal injection pattern, a dense layer of polyurethane compacts and bonds the soil to prevent water seepage and soil loss. Additionally, polyurethane aggressively seeks out and fills voids and seals cavities, cracks, and crevices.
Applications
- Sub-grade vaults and lift-stations
- Mine water infiltration
- Water treatment facilities
- Septic waste systems rehabilitation
Infrastructure
Leak Sealing
Manhole Repair
Manholes often experience cracks, leaks and soil erosion. Poly-Mor Canada’s polyurethane foam injection is a no-excavation repair solution that can restore the manholes back to full functionality. Not only will our polyurethane foam seal joints against water ingress and egress, it will stabilize the base soils and fill voids – thus strengthening the support for all adjacent infrastructure such as roadways, sidewalks and buildings. As with all Poly-Mor Canada solutions, the process is quick, minimally-disruptive, and cost effective.”
Applications
- Storm/wastewater manhole rehabilitation
- Culverts, utilidors and other sub-grade conduits
This technology is applicable in the industrial, commercial, residential, public works and institutional markets where water leaks are a problem.
