T30 Hollow Injection Bar

T30 hollow injection bar is suitable for granular soils and fills. This installation method utilizes a Grout Swivel, grout pump and drifter. The technique combines drilling and grouting as a single operation, ensuring that grout is placed over the full length of the borehole. For ground conditions where borehole collapse is anticipated or where subsequent grout injection down the center of the bar is problematical, T30 hollow injection bar is the preferred solution.
