||Basement Construction - Reinforced Concrete Foundations
The construction of basements has become popular in urban areas, especially London where there is little scope for extending domestic properties. Often the only means of extending a property is by adding a basement.
Access to the site was extremely restricted and extensive liaison and co-ordination was required with the local highways department and residents on the mews to minimise disruption during the works and co-ordinate access for plant and material deliveries.
The project consisted of the underpinning of the perimeter walls following demolition of the core of the building by the main contractor. Once the underpinning and excavation had been completed, a lateral propping system was installed.
All Foundations utilised an external waterproofing system in conjunction with waterproof concrete to seal the basement against water ingress. They had to adopt strict quality control procedures to ensure compliance with waterproofing specification. The basement project was completed with the erection of a falsework deck to allow the casting of a suspended reinforced concrete slab at ground level. This
formed the new ground floor.
Ian Cull, Southern Regional Director commented, “We
are building a reputation for our work on basement
construction. A lesser contractor would have had
difficulty with the access conditions, but All
Foundations managed to complete the project on
time and within budget.”
