minimal disruption – even inside existing buildings or narrow rear gardens typical of London housing.

Why Mini Piling Is Ideal for London Properties
London’s diverse ground conditions – from London Clay to River Terrace Gravels – make mini piling one of the
most reliable foundation systems available. It performs well in restricted spaces, reduces vibration and
delivers engineered strength that exceeds conventional strip foundations.
- House extensions where access for large rigs is impossible,
- Basement and underpinning works beneath existing structures,
- Garage or conservatory foundations on poor or made ground,
- Retaining walls and slope stabilisation,
- Commercial infill sites and tight urban locations.
Mini piles can carry significant loads despite their smaller diameter – versatile, clean
to install and fully compatible with London’s party wall regulations.
What Is Mini Piling?
Mini piling is a small-diameter, deep foundation technique using compact rigs and sectional
augers or casings. Piles typically range from 150 mm to 400 mm in diameter and can reach depths up to 15 m.
- Augered Mini Piles – low-noise, low-vibration; ideal for residential work,
- Driven Steel Case Piles – suitable for granular soils and rapid installation,
- Grouted Anchor Piles – used where lateral restraint is required,
- Sectional Flight Auger (SFA) – perfect for low headroom situations such as basements.
Each method is selected following a ground investigation and structural assessment.
