Every successful basement begins with accurate investigation. Our specialist surveys provide the technical certainty required to design and construct complex basements with confidence.

Basement Surveys Designed to Eliminate Risk

Basement Structures North delivers comprehensive surveys and investigations tailored specifically for underground construction. Unlike generic site surveys, our approach focuses on the structural, geotechnical and waterproofing challenges unique to basement projects.

We work closely with RIBA architects, structural engineers and CSSW waterproofing specialists to ensure every basement scheme is supported by robust technical data before excavation begins. This early-stage diligence is critical for protecting neighbouring properties, safeguarding heritage assets and ensuring compliance with BS 8102:2022 and BS 5975 temporary works standards.

Intrusive & Non-Intrusive Basement Investigations

Our investigation services include trial pits, boreholes, soil sampling, groundwater monitoring and existing structure assessments. These investigations inform basement sequencing, temporary works design, waterproofing strategies and structural solutions.

Whether working beneath period properties in Cheshire’s Golden Triangle, constrained urban sites in Manchester or rural estates across Yorkshire and the North East, our surveys are tailored to the risks and sensitivities of each location.

Why Basement Surveys Matter

Reducing uncertainty before construction begins

Basement projects carry inherent risk without proper investigation. Ground conditions, water tables, adjacent foundations and historic construction methods all influence basement feasibility and cost.

Our surveys allow informed decisions at planning and design stage, reducing the likelihood of programme delays, design changes and unforeseen costs once excavation is underway.

Basement Surveys & Investigations FAQs

Basement surveys focus on groundwater, lateral ground pressure, adjacent foundations and structural sequencing—factors not typically covered by standard site investigations.

In most cases, yes. Boreholes and trial pits provide essential data on soil strata, groundwater levels and bearing capacity that cannot be reliably assumed.

Yes. Early investigations often strengthen planning submissions and inform basement design strategies before detailed consent is granted.

Absolutely. We integrate survey data directly into structural, waterproofing and temporary works design with the wider consultant team.

We undertake basement surveys across Northern England, including Cheshire, Greater Manchester, Yorkshire, the North East and the Lake District.
