DSI Injection Piles comprise of a self-drilling micropile (or mini pile) that can be injected with grout during installation. The fully threaded rod sections can be cut and coupled at any point, enabling quick and easy installation in areas of restricted access or limited headroom.

Installation of DSI Injection Piles causes minimal disturbance to surrounding structures.The system also enables additional rod sections to be added in-situ, for pile extension in poor ground where the founding level is uncertain. Simultaneous drilling and grouting ensures that the grout is continuously placed over the full depth of the micropile, enabling grout to permeate the surrounding ground and increase skin friction. Rotary percussive installation ensures high rates of production and provides good directional stability if obstructions are encountered.

Applications for DSI Injection Piles include: stanchion bases, foundation upgrades, mast stabilisation, refurbishment of old structures, and gantry bases for overhead power lines on rail electrification projects.
