Steel case driven mini piles→

How it works

A steel casing is driven into the ground by a compact drop hammer or ground-displacement rig, then reinforced and filled with concrete. The rigs are small enough for back gardens, narrow side access and work inside buildings, and the casings can be cut or extended on site to suit the ground.

When it’s used

Steel case driven piles are typically considered for made ground, sands and gravels, contaminated ground and ground with a high water table. As mini piles, they’re used for new build foundations, extensions, underpinning and properties affected by subsidence.

Advantages

• A straightforward, cost-effective solution for lighter loads
• Flexible: piles are easily cut or lengthened, and casings come in any length and a wide range of diameters
• No arisings, so no spoil disposal costs and minimal waste
• Displacement piles are the preferred option in contaminated ground
• Useful on restricted access sites where removing spoil is difficult and costly
