Geddes, NY: Reach 2 Pump Station Jet Grouting
Geo-Solutions Inc. installed cement columns that serve to both underpin and seal the Reach Two pump station.
The work consisted of installing and testing jet grouted columns to create both an impermeable encasement around the pump station, as well as underpin the pump station to meet the acceptance criteria stated in the client specifications.
- Installation of 16 jet grout columns. In which 8 columns were installed from ground surface to 60' BGS and 8 columns from ground surface to 18' BGS.
The construction created a groundwater cut-off system while also providing a foundation to support the pump station. The cut-off system eliminated the infiltration of groundwater into the pump station.
Geo-Solutions was responsible for overall quality control of the stabilization activities which included process controls to ensure accurate reagent addition as well as laboratory testing on field collected samples of the mixed materials.
This project was successfully completed having met all of our client's expectations, as well on schedule and within budget.
The overall goal of this project was to increase the strength of the soils below the edge of the manhole foundation and to significantly reduce seepage infiltration through the sides of the manhole.
