Little Acres was a large hole in the ground which was being turned into a luxury house with a large basement which was to be a cinema and games room.

 
The excavation filled with water...
 
To comply with BS 8102 the ground was drained by means of pumps, sumps and land drainage. The outside of the building was  encapsulated with MS 20 below the slab (Shown being installed) and Geo Drain over the walls to stop any pressure of water.
 
The pictures show LSE water proofing staff installing MS 20 onto the slab. Concrete slab reinforcement on the MS20.
The inside was lined with System 500 on the walls and MS 20 on the floors with drainage to a large external sump and pumps.
