Permeation Grouting

Permeation grouting is the injection of a fluid grout into granular, fissured or fractured ground to produce a solidified mass to carry increased load and or to fill voids and fissures to control water flow.

Sands, gravels and coarser open materials, fissured, jointed and fractured rock can be treated.

 With  permeation grouting we can achieve;

  • Grouting to a pre-determined size and depth of treatment area.
  • Flexibility to increase scope of treatment
  • Significant and predictable degrees of improvement.

 

Generally the system is non vibratory.

Grout types are usually cement-based but can be blends according to the soils we are trying to treat; such as Cement/Bentonite, Cement/Sand,Cement/PFA/GSBFS or even Microfine Cement.

Some special applications require Sodium Silicates, Polyurethanes  or Resins

Method

Ranging from hand lancing and ‘end-of-casing’ methods, ascending and descending stage grouting to tubes-a-manchette (TAM) methods wherein sleeved ports TAM pipes are installed in a pre-determined pattern horizontally, inclined or vertically.

Permeation of the ground is by controlling flow rates and pressures to fully treat the target area.  Re-injection via adjacent or previously injected ports is possible.
