The complete grout swivel lets the grout line stand still while the drill string turns: a heavy-duty bearing assembly and sealed internal passages carry cementitious grout, slurry or epoxy into a rotating string without twisting hoses or loading fittings. Male-male thread configurations in R32, R38 and T38 drop into standard soil stabilization strings the same strings that run carbide cross bits for structural repair, underpinning, void filling and anchor grouting.
A smooth-bore flow path minimizes pressure drop with viscous slurries, and hardened bearing surfaces with anti-extrusion seals stand up to abrasive entrained solids; it arrives as a complete assembly for minimal on-site setup. For injection through the drill string itself, see the Rotojec shank and grout injection body; rods and bits for the rest of the string are in drill steel & bits.

Grout Swivel FAQ
What does a grout swivel actually do?
It lets the grout hose stay stationary while the drill string rotates. The bearing assembly absorbs the rotational stress, so the hose doesn’t twist, kink or load its fittings while grout is pumped under pressure.
What thread configurations does the complete grout swivel come in?
Male-male R32, R38 and T38. Pick the thread that matches your drill string — the same R32/R38/T38 threads used on the extension rods we stock.
Will it stand up to abrasive, solids-laden grout?
Yes. Hardened bearing surfaces, anti-extrusion seal rings and a smooth-bore flow path are designed for cementitious slurries with entrained solids, minimizing wear and pressure drop in cyclic, pressured service.
