O’Halloran & O’Brien delivers complex basement construction solutions for residential, commercial and mixed-use developments across the UK. Our expertise covers deep excavations, retaining structures, waterproofing systems and permanent concrete works, all delivered with the precision, planning and control required in confined environments.
We combine temporary works design, technical coordination and rigorous safety management to deliver basements safely, efficiently and to the highest structural standards.
Our teams manage every stage of basement excavation, including reduced level digs, propping, sheet piling and retention systems. Working alongside our in-house Construction Engineering Team who develop the temporary works scheme, we ensure stability and compliance throughout the excavation process.
We construct permanent basement slabs, retaining walls and waterproof structures to meet project design and performance requirements. Our experience includes Type A, B and C waterproofing systems, all installed under strict quality control to achieve watertight performance and long-term durability.
Basement construction demands careful coordination and control. We apply detailed logistics planning, sequencing and confined space procedures to maintain productivity and protect all personnel and surrounding structures. Through advanced 3D and 4D modelling, we simulate excavation stages, temporary works and access arrangements to optimise safety, efficiency and buildability.
O’Halloran & O’Brien’s approach to basement construction combines engineering precision, collaboration and proven delivery expertise. By integrating excavation, temporary works and structural concrete within one coordinated package, we provide clients with safe, efficient and high-quality basement solutions that stand the test of time.
