What are helical piles?

Helical piles are steel shafts with helical plates welded at intervals along the shaft. They are screwed into the ground using hydraulic equipment, much like a large screw. The helical plates provide bearing capacity in the ground, supporting the structure above.

When are helical piles used instead of traditional underpinning?

Helical piles are preferred when stable ground is too deep for mass concrete underpinning, when access is restricted, when vibration must be minimised, or when the ground contains voids or very soft layers that cannot support traditional foundations.

How deep can helical piles go?

Helical piles can typically be installed to depths of 15-20 metres, though deeper installations are possible with extension shafts. The depth is determined by ground conditions and the location of suitable bearing strata.

How are helical piles connected to existing buildings?

Helical piles are connected to existing foundations using steel brackets that are bolted or cast into the existing structure. For new builds, pile caps are cast on top of the pile heads to support the new foundations.

Are helical piles suitable for Truro's ground conditions?

Yes. Helical piles are well suited to Truro's variable geology, including areas with shallow mine workings, clay soils, and made ground. They can penetrate through poor ground to reach competent bearing strata at depth.

Q: Why do properties in Truro experience subsidence?

Truro has specific ground conditions that contribute to subsidence risk. Truro's riverside location means many properties contend with high water tables and clay-rich alluvial soils. The city's elegant Georgian terraces and Victorian villas were often built with shallow foundations that are particularly susceptible to ground movement. These local factors mean that subsidence investigation and repair in Truro requires specialists who understand the area's unique geology and building traditions.

Benefits of Helical Piling in Truro

Low Vibration

Helical piles are screwed in, not hammered. This means minimal vibration and noise — important in residential areas and near sensitive structures.

Immediate Loading

Unlike concrete piles, helical piles can be loaded immediately after installation with no curing time required.

Tight Access

Compact installation equipment means helical piles can be installed in restricted access locations where conventional piling cannot reach.
