Services
Groundworks
We deliver complex substructure works including deep basements to 20m depth, enabling works, and foundation packages across London. Our expertise covers propping systems, CDP waterproofing, and underpinning in constrained urban sites. Using our own plant fleet, we handle site clearance, cut and fill operations, and drainage installations with material reuse optimisation.
Concrete Frames
Specialists in reinforced concrete frames for residential towers, mixed-use developments, and institutional buildings. We employ traditional shuttering, Twinwall systems, and jump form techniques. Our post-tensioned slab solutions reduce building height while modern formwork systems ensure Class A finishes. Projects include Exeter College's academic building and Three Waters residential towers.
Preconstruction
Our preconstruction team provides feasibility studies, buildability assessments, and cost planning from early-stage forecasting to Stage 4 sign-off. We develop construction strategies with sequence drawings, crane logistics, and value engineering for waterproofing and reinforcement systems, ensuring programme efficiency and risk reduction.
External Works
We create durable external environments with natural stone paving, soft landscaping, and bespoke street furniture. Our projects include The Tide riverside park's public realm landscaping and Royal Holloway University's grounds. We integrate irrigation systems, planting beds, and water features tailored to each site's character.
Paving
Specialising in premium paving materials including granite and limestone. We install durable surfaces for public realm projects like Greenwich Peninsula's elevated park. Our work combines traditional techniques with modern installation methods, ensuring long-lasting finishes that withstand heavy usage while maintaining aesthetic appeal.
