Grouted Helical Piles

Foundation Supportworks' Helicast^™ Grouted Pile System consists of solid square shaft lead and extension sections (Models HA150 of HA175), with a lead displacement plate located at the first extension coupler and one displacement plate at each of the following extension couplers.

The pile is advanced through a grout reservoir at the surface. The lead displacement plate pushes soil outward and away from the central shaft and allows the specialty micropile grout from the reservoir to flow via gravity in the created void. The extension displacement plates help maintain the size and shape of the grout column as the pile is advanced through the soil.

The Helicast^™ System develops capacity from the combination of helix plate end-bearing and the grout column's friction resistance. Allowable compression system capacities of up to 100 kips can often be achieved when bearing within adequate soil conditions.
