Commercial Basement & Substructure Contractors in London
McGrath Civils specialises in commercial basement and substructure packages across London and the Home Counties. We self-deliver all reinforced concrete works in-house, providing developers and main contractors with a technically capable partner responsible for excavation, structural concrete and below-ground infrastructure from start to completion.
From reduced dig basements beneath redevelopment schemes to large-scale reinforced concrete substructures for multi-unit conversions and commercial builds, our focus is on structured, programme-driven delivery.

Reduced Dig & Commercial Basement Construction
Many London and urban developments require reduced dig solutions to manage ground conditions, structural constraints and budget considerations. These schemes demand careful planning to maintain stability, protect adjacent properties and coordinate temporary works safely.
Our commercial basement capabilities include:
- Reduced dig excavation strategies
- Bulk excavation and controlled soil removal
- Piling mat preparation
- Reinforced concrete basement slabs
- RC retaining walls and lift pits
- Ground beams and structural bases
- Coordination with waterproofing systems
Basement works are often the most technically sensitive phase of a project. We work closely with structural engineers and temporary works designers to ensure excavation and reinforced concrete construction is carried out safely, accurately and in accordance with programme requirements.
In-House Reinforced Concrete Expertise
Reinforced concrete is a core discipline within McGrath Civils.
All RC works are delivered directly by our own experienced teams, ensuring quality control, consistency and accountability across every project. Our substructure RC works typically include:
- Basement slabs and suspended slabs
- Reinforced concrete retaining walls
- Pile caps and ground beams
- Lift shafts and stair cores at substructure level
- Service pits and structural bases
By self-delivering reinforced concrete packages, we maintain control over sequencing, workmanship standards and coordination with adjacent trades. This reduces risk and supports programme certainty for our clients.
