Basement Structures North delivers precision-engineered structural excavation for luxury basements, combining temporary works expertise, controlled sequencing and robust risk management on challenging northern sites.

Engineered Basement Excavation & Ground Support

Structural excavation is the most critical phase of any basement project. We undertake complex excavation works beneath existing structures, tight boundaries and restricted access sites, ensuring stability at every stage.

Our in-house delivery team works to a fully designed temporary works strategy in accordance with BS 5975-1:2024, with appointed Temporary Works Coordinators and Supervisors overseeing sequencing, inspections and compliance.

From mass dig to staged underpinning and formation level, every excavation is carefully planned to protect neighbouring properties, services and superstructures.

Underpinning, Restricted Access & Complex Sites

Many luxury homes across Cheshire, Yorkshire, the North East and the Lake District present complex constraints — tight plots, shared walls, heritage structures and live occupancy.

We specialise in traditional mass concrete underpinning, reinforced solutions, piled sequences and needle beam support, enabling safe excavation beneath existing foundations without compromising structural integrity.

All works are coordinated alongside engineers, architects and local authorities, with method statements and monitoring regimes tailored to each site.
