When is underpinning necessary?

Underpinning is typically required when foundations have settled due to subsidence, when existing foundations are inadequate for the ground conditions, or when alterations to a building increase the loads on existing foundations. A structural engineer's assessment determines whether underpinning is the right solution.

What types of underpinning are available?

The main methods are mass concrete (traditional), beam and base, mini-piled, and resin injection. Mass concrete is the most common for residential properties. Mini-piling is used where deeper stable ground is needed. Resin injection is a less invasive alternative where ground conditions permit.

How much does underpinning cost in Truro?

Residential underpinning in Truro typically ranges from £10,000 to £50,000 depending on the extent of work, depth required, and access conditions. We provide detailed quotations after a thorough site investigation.

How long does underpinning take?

A typical residential underpinning project takes 3-6 weeks depending on the number of bays, depth of excavation, and weather conditions. We work in sequential bays to maintain structural stability throughout.

Can I stay in my home during underpinning?

In most cases, yes. The work is carried out externally and you can continue to occupy the property. However, there will be noise and disruption from excavation equipment, and access around the property may be restricted.

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.
