Tenders are invited for works includes approx 15,730 lf of 8"-10" sanitary sewer, cipp lining; 266 lf of 10"-16" barrel lining, siphon; 174 ea of 8"-10" main, reinstate service lateral; 700 ea test and seal 10" sewer main joints in basin c01; 200 gal chemical grout

The solution was use of a single-component, urethane chemical grout
called AV-310 Hydro Sealant from Avanti International.
is specifically designed to stop infiltration at pipe joints and laterals, and its use to seal laterals after lining is a cost-effective alternative.
workers were injecting chemical grout
to seal ``routine'' tunnel cracks near Vermont Avenue and Melrose Avenue when they smelled the gasoline vapors.
Tenders are invited for provide for the rehabilitation of approx 38 ea sanitary sewer manholes by the application of structural lining products to all interior surfaces, 1 ea chemical grout
mobilization, 100 gal installed chemical grout
material, including channel, bench, barrel, cone and chimney sections.
This marked the birth of chemical grout
, which National Power Rodding soon had the opportunity to prove could greatly help solve water infiltration problems.
Since its development in the early 1950s, chemical grout
has been used to stop water movement through soils in mines, earthen dams, tunnels, and excavation sites.
The sealing of sewer lateral connections (aka "services") with chemical grout
continues to gain popularity across the country.
Now, there is good evidence that cities can actually save money by sealing those laterals with chemical grout
If chemical grout
is the best solution, or part of the solution, the following information will be beneficial.
Pressure inject chemical grout
around perimeter of RCP Joint at the catch basin.
was the first trenchless pipeline rehabilitation process and, when properly applied, it is still the best cure for infiltration of groundwater.
