Recently NG Tunnelling were asked to carry out sewer connection works in Maida Vale:

Our bespoke solution comprised of
• A slightly longer shaft than usual, at 2.5m distance, was excavated onsite to make allowance for an interceptor trap and manhole
• A timber heading was driven to Thames Water’s culvert, and a flexible saddle connection was core drilled, in line with Thames Water’s requirements.
The works were part of Westminster Council’s redevelopment of the Torridon House Estate car park to construct 21 new homes.

NG Tunnelling is a family-run company, offering specialist installations of drain & sewer connections in London & Surrey.
