    Ultrafine Grout

    Ultrafine Grout is composed of a finely ground mixture of Portland cement, pumice pozzolan, and dispersant. Ultrafine cementitious grout has an average particle size of 3 microns, in stark contrast to typical particle sizes of 60 to 70 microns in conventional cements. Ultrafine SD grout is formulated with a naphthalene sulfonate-based superplasticizer for a foolproof system with minimal bleed and high compressive strengths for rock fracture and soil stabilization applications.


    • Stabilize weak soils.
    • Seal seepage in mines, dams, tunnels, casing vent leaks, cement squeezes, etc.
    • Low permeability grout curtaining.
    • Hazardous waste containment.
    • Oil well squeeze cementing.
