Soldier piles: a wall of drilled concrete piles for a moving slope.
Large drilled concrete piles set tightly in a line, through the fill and into dense native soil, to hold back a moving slope.
Let's take the first step toward solid ground.
A local specialist will evaluate your foundation, walk you through the findings, and send a clear estimate. No cost, no pressure.
What to know about soldier piles, and when it's the right call.
On a man made slope, fill that was not compacted properly makes the slope unstable. Fill is soil that was brought in and placed to shape the slope. Native soil is the dense ground that was already there. Soldier piles work by reaching past the fill into that native soil. Each one is a large drilled concrete pile, and the piles are installed tightly together so that, in a line, they act as a wall. With the piles supported by native soil, the soil behind them is compacted back into place and the slope is held. Soldier piles are one of the hillside repair methods we use, alongside grouted soil nails and retaining wall systems tied to piers. Because every slope is built differently, the choice between them comes from the evaluation, not from a price list.
The symptoms that usually lead to soldier piles are on the hillside repair problem signs page, alongside the other signs that point to the same underlying cause.
How we install soldier piles.
Free evaluation of the slope
A specialist looks at the slope, how it was built and the signs of movement around the house, then explains what the evaluation found.
A design that fits the slope
Soldier piles are one option in hillside repair for homes, and they are matched to slopes that call for them. Every method is designed to fit the slope's current condition.
Drill the piles
Special drilling rigs drill each pile through the fill material and into the dense native soil that supports it.
Set the piles in a line
The large concrete piles are installed tightly together, so the line of piles works as a wall.
Compact the soil behind them
Soil is compacted back behind the piles, and the slope is retained.

A soldier pile is a large drilled concrete pile. Installed tightly together in a line, soldier piles form a wall that retains a slope. They are drilled through the fill that makes up the slope and into dense native soil for support.
