With expertise in extensions, new builds, and renovations, we ensure compliance with regulations while prioritising client needs. Our integrated approach streamlines processes from concept to completion.
Subsidence Repair
Specialising in subsidence, heave, and landslip remediation, we conduct detailed site investigations to identify root causes. Our solutions include underpinning, ground stabilisation, and superstructure repairs. Using advanced techniques like resin bonding and helifix systems, we restore structural integrity with minimal disruption to properties across the UK.
Assured Foundations
We design and install traditional and piled foundations with a 12-year insurance-backed guarantee. Services include pad and beam foundations, raft slabs, and pressure relief systems. Our engineers assess ground conditions to recommend cost-effective solutions, ensuring long-term stability for new constructions or existing properties requiring reinforcement.

Traditional and specialist underpinning services address structural movement in existing buildings.
