Chemical Grouting or Micro-Fine grouting, is poured into less porous soil types to fill voids and spaces to make the soil stronger. Chemical grouting is used to create barriers to groundwater flow, provide a stronger foundation for structures, provide needed support for excavation, allow exfiltration of sewer joints, and to stabilize soil for tunneling.

Featured Project

Project Details

Hardman was hired to stabilize soil within an existing building. The complete project was to build test stands for motors. The existing structure was just a floor slab with exhaust pipes for the existing testing stand below grade. The existing slab needed to be removed and 78 tube manchets were placed along the perimeter of the room to allow installation of 14,000 gallons of micro-fine grout. This allowed the soil along the perimeter of the room to be stabilized and for an excavation of 6′. All combustion engine running machines needed to be outside the building and then piped to the work area (Grout Pumps & Welders). Any other machines needed to be tier 4 or electric inside the facility. The project lasted two weeks and all work was done at night to continue plant operation.
