Micro piles have been used effectively in many applications of ground improvement — not only as working piles carrying high loads in constrained areas, but also for strengthening existing foundations. They are one of the most efficient deep foundation systems available, tolerating very large loads for their small size when socketed into rock.

With rigs of various sizes, we construct micro piles from just 75mm up to 300mm in soil, and 90mm to 250mm in rock — even in very constrained areas using our small drilling frames. Construction methods include wash (recirculation) boring with a drag bit, roller (tricone) bit for stiffer soils, or casing and shoe for drilling through buried timber and organic deposits. For rock, we employ the Down-the-Hole Hammer (DTH), a bottom-driven self-actuating hammer that can penetrate all rock types, including Grade I granite.

A failing hillside or earth mass is "stapled" in place using inclined nails — a drilled, grouted hole with a single piece of reinforcement bar — creating a single block of earth able to hold back its overburden. Slope equilibrium remains essentially undisturbed throughout construction, making it practical for immediately arresting potentially failing slopes.

Beyond ground engineering, our team carries out marine works and structural rehabilitation — from jetty repair and pile jacketing to fender replacement and protective works in marine environments. Our repair of the jetty for APMM Cukai included pile jacket work, crack repair, fender replacement, roofing and painting — delivered with the same commitment to safety and quality as our ground engineering projects.
