Underpinning
Underpinning involves strengthening the existing foundations of a building to provide additional support. This is typically required when the original foundation is no longer strong enough to support the structure, often due to changes in soil conditions, nearby construction, or subsidence damage.
Key Benefits
Building regulations compliant
Can increase property value
Long-term foundation stability
Multiple underpinning methods available
Structural engineering expertise
Suitable for all property types

Frequently Asked Questions
What types of underpinning do you offer?
We offer several methods including mass concrete underpinning, mini-piled underpinning, beam and base systems, and resin injection. The best approach depends on your property's specific ground conditions and structural requirements.
How much does underpinning cost?
It varies depending on the property size, depth of foundations, and method used. We provide free, no-obligation quotes after an initial assessment so you have a clear picture of costs before any work begins.
Is underpinning disruptive?
It can be, depending on the method. Traditional mass concrete underpinning involves excavation and is more disruptive. However, modern alternatives like resin injection are far less invasive and can often be completed in a day.
Do I need planning permission for underpinning?
No, planning permission is not usually required. However, building control approval may be needed depending on the scope of work. We handle all necessary approvals as part of our service.
