Permeation Cement & Chemical Grouting

Proudly Servicing the Greater Alabama Area

Pressure Grouting AlabamaPermeation grouting is the most common, and oldest form, of soil grouting. The technique consists of drilling a hole in the soil, inserting an injection pipe into the ground and then pumping any number of liquefied materials into the problem area. How the hole is drilled, type of injection pipe, and what material is used, are all determined by the specifics of the repair being performed. This type of grouting is typically limited to sandy soil conditions as this type of soil allows the grout to permeate more readily over a wider area.

Pressure Grouting Cement Grouting

Cement grouting, the most common form of permeation grouting, is the injection under pressure grout. Nichols / Grout Tech utilizes Portland cement-based grout and pumps it into a soil or rock formation to fill voids or fractures in the formation. For example, if a large concrete floor slab were tilting to one side, a grout pipe could be installed under the low side of the slab where the tilt was occurring. Grout could be injected under the slab that would act like a “hydraulic jack” that could then raise the slab back to its desired angle. In other common applications, the grout is injected into rock fractures to improve the stability of the rock formation. Cement grouting is commonly used for the following types of improvement.

  • Pre-construction site improvement.
  • To arrest foundation settlements.
  • Stop rocking slabs in warehouses.
  • Repair fractures in machine bases.
  • Rectify sinkhole problems.
  • Lift and level slabs and foundations.
  • To control soft-ground settlements in granular soils.

    Chemical Grouting, another common form of permeation grouting that has gained popular acceptance to strengthen granular soils such as sand, is the injection of chemical solution grouts that bond the individual grains together into tone like masses that are capable of carrying loads of the structures. The chemical solutions typically consist of a base material that is mixed with a hardening agent that causes the mix to harden at a predetermined rate, depending on the compounds used and length of set time desired for a particular application. Chemical grouting is also commonly and extensively used in the following applications:

    To limit ground movement during excavation and construction (lagging operations).

    • Leaking subterranean structures to control water flow.
    • Footing support.
    • Grouted tunnel support.
    • Pit excavation below water
