Piling Contractors in St Albans – Mini, Micro & Restricted Access Piling Specialists
As established piling contractors in St Albans, Arma Piling designs and installs foundation systems that deliver long-term structural stability on every type of site — from period properties in Marshalswick and Harpenden to new-build developments around Wheathampstead and London Colney. Our crews have completed countless mini piling and micro piling projects across St Albans and wider Hertfordshire, working confidently around the area’s chalk overlain by clay-with-flints and glacial till.
Our mini piling services in St Albans are ideal for sites with limited headroom or difficult access — a common challenge across St Albans’s historic centre, conservation areas and period properties. Using compact, low-vibration rigs, we install mini piles for house extensions, retaining walls, underpinning and refurbishments without disturbing neighbouring structures. For heavier loads, our micro piling solutions provide exceptional capacity with minimal disruption — ideal for basements, commercial builds and groundworks.
What is micro piling?
Micro piling (also called mini piling or pin piling) is a foundation technique using small-diameter piles (typically 100–300mm) that are drilled into the ground and reinforced with steel and grout. It’s used when standard piling is not possible due to access limitations, low headroom, or ground conditions.
At Arma Piling Ltd, we’re proud to be one of the most trusted local piling contractors near St Albans, delivering safe, durable and cost-effective foundations across Hertfordshire and the surrounding region.
