Saving a Notting Hill Failed Double Basement

Newton was approached by the desperate client at this large terraced property in Notting Hill, having had a second basement level excavated beneath the existing basement and the front and rear gardens.

Unfortunately, bad waterproofing design and workmanship meant the basement had flooded immediately upon completion – the builder ceased trading and, following a legal case, the architect and structural engineer were found culpable.

We recommended our experienced specialist contractor Stonehouse in order to assess the failure and propose a comprehensive solution.

The experts at Stonehouse identified a litany of issues, from the weak, permeable structure to the lack of continuous waterproofing between levels, the inadequate pumping system, the blocked cavity drain system, and the non-existent external deck waterproofing and drainage, amongst others.
