Underpinning in Washington
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.
Underpinning for Washington Properties
Washington new town was built over an area of extensive coal mining on Coal Measures geology. While modern development areas have engineered foundations, some zones are affected by shallow mine workings.
Coal Measures with glacial till overburden. Extensive historic coal mining at various depths, including shallow workings, creates ongoing subsidence risks in parts of the town. Our underpinning service is tailored to these local ground conditions.

FAQs
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 method depends on your property's specific foundation type, soil conditions, and the extent of movement.
How much does underpinning cost?
It varies. Costs depend on the property size, depth of existing foundations, chosen method, and ground conditions. We provide free, no-obligation quotes after an initial survey so you know exactly what to expect.
Is underpinning disruptive to my home?
It can be, depending on the method. Traditional mass concrete underpinning involves excavation and can be 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, generally not. However, building control approval may be required depending on the scope of work. We handle all necessary approvals and certification as part of our service.
