The architectural design of the house meant that the basement walls had to be almost 4m in height, more than a meter higher than most builds. This caused issues with both the restraint of the concrete during construction and the aspect ratio of the walls.

From a health a safety standpoint the higher walls presented further challenges and fall arrest issues.

For this project the client and their design team wanted a specialist basement building company to carry out the works.

Build Method

Beautiful Basements was appointed as the specialist designer and builder for the basement for the new build of a very large house in rural Nottinghamshire.

The basement was to built from reinforced concrete (RC) walls and slab to create the foundations for the house above. The client’s main contractor carried out the excavation and the blinding of the formation level. Beautiful Basements then created the slab, fitted the three pumping stations, built the shuttering for the walls, installed the steel work and cast the RC basement walls.

Waterproofing Method

Type C – Internal Cavity Drainage System

Internally the main floor slab was cast to fall, meaning gravity would divert any water to one of the two groundwater sump stations.

The walls and floor were lined with a cavity drainage membrane (CDM)

Two pumps and one high level alarm were fitted to each of the sump stations

Membranes & sumps were supplied by Triton Systems.

Externally the walls, kicker and slab toe were treated with a waterproofing slurry to slow any water ingress.

External slurries were supplied by Koster Aquatecnic.
