Driven Piles & Micropiling
RC piles, spun piles, and high-capacity micropiles. From large open-site driven pile contracts to precision micropiling in basements and through existing slabs — we have the equipment and expertise for both ends of the spectrum.
Conventional Driven Piling
RC & Spun Driven Piles
Precast reinforced concrete and spun concrete piles driven using conventional piling rigs. Suitable for open-access new-build sites requiring high axial load capacity.
- RC square piles
- Spun concrete piles
- High driving energy
- Large open sites
Precision Micropiling
Micropiling
Small-diameter drilled and grouted piles for restricted access, low headroom, and underpinning work. Can be installed through existing slabs and in basements.
- Restricted access sites
- Low headroom environments
- Underpinning of existing structures
- Through-slab installation
Technical Approach
How We Work
Site Assessment
Review soil investigation reports and site constraints. Our engineers recommend the most appropriate pile type, section, and length for your specific ground conditions.
Mobilisation & Setup
Equipment selected to match site access. Driven pile rigs for open sites; compact micropiling rigs for restricted access, through-slab, or basement conditions.
Installation & QA
All piles installed to specification with full records kept. Dynamic load testing (PDA/CAPWAP) or static load testing arranged as required by the project engineer.

Common Questions
Driven Piles & Micropiling FAQ
What is micropiling?+
Micropiling uses small-diameter drilled holes (typically 100–250mm) filled with high-pressure grout and a steel reinforcement cage to create a high-capacity pile. Despite its small size, each micropile carries significant axial loads — ideal where conventional rigs cannot access.
When is micropiling used instead of driven piles?+
Micropiling is chosen for restricted access: inside existing buildings, through concrete slabs, in basements with low headroom, or when underpinning an existing structure. Driven piles are better suited to large open-access sites where high output and low cost per pile are priorities.
What minimum headroom is needed for micropiling?+
Foundtech's micropiling rigs can operate in as little as 2–2.5m headroom, making them suitable for basement retrofits, underfloor strengthening, and interior structural works. Equipment selection is confirmed after a site survey.
Can micropiling be installed through an existing concrete slab?+
Yes. Micropiling drills and groutes through existing reinforced concrete slabs, allowing new piles inside an occupied building without demolishing the floor structure — one of its most valuable capabilities for retrofit and underpinning work.
