Piled Underpinning in Taunton SW — Strengthening Foundations with Piles

Piled underpinning is chosen where the ground movement is deep, where access is restricted, where the existing foundation is hard to underpin traditionally, and where the building needs to be stabilised quickly. It suits Victorian and Edwardian properties, terrace extensions, and basement conversions.

Typical piled underpinning projects include stabilising subsiding Victorian and Edwardian homes, underpinning for basement conversions, and strengthening foundations for extensions on weak ground.

Piled underpinning installs piles — often mini piles or restricted access piles — next to or beneath an existing foundation, then ties them to the structure with a reinforced concrete beam. The piles take the load down to a competent stratum, bypassing the weak or moving ground that caused the original settlement. It is less disruptive than traditional underpinning and works on restricted access sites.

We carry out a subsidence survey in-house to diagnose the cause of movement. Our design team specifies the pile type, depth and the connecting beam. The piles are installed — often with compact or restricted access rigs — and the reinforced beam ties the new piles to the existing foundation. We coordinate with building control throughout.

Piled underpinning cost depends on the number of piles, pile type and depth, the connecting beam specification, and the access constraints. The extent of movement and the cause also affect the scope. We provide a fixed quote within 48 hours of the site visit.

When is piled underpinning better than traditional underpinning?

Piled underpinning is better when the weak ground is deep, when access is restricted, or when the existing foundation is hard to excavate beneath. Traditional mass concrete underpinning suits shallower problems with good access. We diagnose the cause first and recommend the right method.
