A multiple pass, multiple hole permeation grouting operation directed by ECO was implemented via driven, vertical steel sleeve pipes to encapsulate and contain nuclear waste buried in trenches and prevent the migration of radionuclides.
Quick turnaround for grout curtain through rock not amenable to regular or microfine based cement grout.
ECO designed and directed a multi-grout, multi-technique post/pre-excavation grouting program to facilitate two mine slopes through water bearing strata. The grouting operation was executed by ECO trained miners.
A multi-facetted grouting operation included curtain grouting below dams, rock anchors and tunnel grouting operations to facilitate the construction of a hydro project.
A double row grout curtain was constructed around the perimeter of 2 large diameter (100 plus ft) caisson shafts using acrylamide and cement based suspension grout to stabilize and control the water inflow prior to sinking the shaft through the soil and rock formations.
A continuous 265 feet high, vertical grout curtain was installed from the underground donut tunnel around a shaft at a depth of 2,760 ft, under high hydrostatic pressures (400 to 1200 psi) using acrylamide based grout.
