Key Benefits
Discover the advantages of choosing our specialized foundation solutions.
Subsidence Expertise
North London's shrinkable London Clay causes many subsidence problems. We have extensive experience diagnosing subsidence causes (vegetation, drains, soil movement) and designing effective underpinning solutions.
Minimal Disruption
Underpinning is carried out in short sequential sections, allowing buildings to remain occupied. We work carefully to maintain structural stability throughout and coordinate with other trades.
Multiple Techniques
We select the most appropriate underpinning method for each project: traditional mass concrete for straightforward work, mini piling for deep excavations or restricted access, and resin injection for minor issues.
Insurance Approved
Our underpinning work meets all insurance company requirements for subsidence repairs. We liaise with loss adjusters, provide detailed method statements and deliver certified completion documentation.
Our Process
Understanding our methodical approach to delivering quality foundation solutions.
Structural Survey & Design
Structural engineer inspects damage, reviews ground conditions and designs underpinning solution. Identify causes (vegetation, drains, soil) and remediation.
Party Wall & Approvals
Serve Party Wall notices if required. Obtain Building Control approval. Schedule pre-commencement condition surveys of adjacent properties.
Sequential Excavation
Excavate short bays (typically 1m long) in sequence beneath existing foundation. Never adjacent bays simultaneously to maintain support.
Concrete Placement
Cast mass concrete or construct reinforced underpinning beam. Allow to cure before excavating next bay. Pin or dowel to existing foundation.
Monitoring & Sign-Off
Monitor structure during and after works. Structural engineer certifies completion. Provide full documentation for Building Control and insurance.
