Bored retaining wallsAugered pile solutions
More space, same footprint.
As building costs rise and land values stay at a premium, more clients are making better use of the land they already have, by building or adding basements for extra space within their existing boundaries.
This work is usually close to existing buildings, so augered piles are the method of choice. They cause minimal vibration and are one of the quietest forms of piling available.
Our fleet lets us offer continuous flight auger (CFA), sectional flight auger (SFA) and open hole auger (OHA) piling, with rigs sized to suit your site.
- Quiet and low-vibrationSafe to work beside neighbouring buildings.
- Sized to the siteFrom open sites to confined retro-fit basements.
- Contiguous or secantThe wall type to suit the ground and the water.
Bored retaining wallsTwo ways to build the wall
Contiguous or secant.
We offer both contiguous and secant piled walls. Our engineers will recommend the right option once they’ve seen your ground investigation and design.
Contiguous piled walls
A line of bored piles installed side by side with a small gap between them. A cost-effective way to retain soil where groundwater isn’t a major concern.
Secant piled walls
Piles that overlap, cutting into their neighbours to form a continuous wall. Used where the wall also needs to hold back groundwater.

Not the right fit?
Basements and walls often go hand in hand with other foundation work. We can deliver it all as one package.
Flexible construction packagesYour project, your way
Let’s get your project off the ground.
We can deliver the full package below ground, from design calculations and mini piling to reinforced concrete works, or install piles to your own engineer’s design. Either way, your building gets foundations that stand the test of time.
