The Problem:
Aging sewer and stormwater systems across the country are plagued by infiltration and inflow; especially in areas with high water tables and unstable soil. Over time, compacted soils around catch basins, manholes, concrete pipes and culverts relax resulting in deflection of joints and pipe connections. The end result is infiltration of groundwater to the storm and wastewater systems.
This infiltration erodes the surrounding below grade drainage structures resulting in sinkholes, settling roadways and property damage; not to mention the extra cost of clearing blockages and dredging stormwater retention ponds.
The Solution:
It is as simple as installing small temporary probes around the failing infrastructure and injecting an EPA approved, drinking water safe, hydrophobic polyurethane resin which has a 100 YEAR LIFE EXPECTANCY.
When installed under high pressure, the chemical grout migrates through the soil following the path of least resistance filling voids within a 6-10’ radius. It seals large holes and even finite breaches while stabilizing the soil giving it a compressive strength equal to 2,000psi concrete. This process eliminates the need for extended road closures, major excavation, disturbing the surrounding landscape as well as the exorbitant costs associated with traditional repair methods.
