Injection piles

Injection piles

Injection piles can be considered as a simplified variant of steel core piles, as these are drilled directly with the steel blank instead of retrofitting a steel core. Drilling takes place at the same time as a cement slurry is flushed (injected) around the drill bit and the steel blank. Injection piles are often used in friction soils, ie soils that contain a lot of sand, gravel or stone.

The advantage of injection piles is that they have a good penetration ability, they can be drilled even in the event of obstacles in the ground, and that the cement slurry that is flushed hardens in the ground and creates an irregular body along the length of the pile. This irregular body leads to injection piles thus having a very high load-bearing capacity, not only on the tip but along the entire sheath. In terms of price, it can be compared with drilled tubular steel piles, but with the difference that injection piles can be used better for both compressive and tensile loads. We verify the load-bearing capacity of our grouting piles by static test loading (usually test drawing).
