Substructures and Basements

Landmark can assist with the full basement package, including the bulk excavation, muck away, temporary propping and underpinning. Our Project Managers and Logistics team have experience in delivering complex basement projects across the South of England and frequently work in inner city locations.

We have extensive experience in single level box basements, subbasements and slabs. We work closely with clients at the pre-construction stage, to establish ground and underground conditions. Typically, this would include soil contamination checks – essential on most brownfield sites – and water table heights, soil saturation and any underground services that have been identified.

The range of basement construction work we undertake includes reinforced concrete/ precast concrete/ cavity filled blockwork/ EPS formwork, waterproofing and the installation of waterproof membranes. We also specialise in areas where there is a major water issue, by installing a dewatering system. To facilitate this, we have experience in the design and installation of pump stations for the associated drainage.
