This scheme was originally planned using Guided Auger Boring for a 15m length of 225mmØ sewer drain, passing below a busy main road outside the site entrance for connection to the public sewer on the opposite side of the road.

However, it was then later found the sewer was not only deep but also close to the kerb with the added complication of multiple other utility services between this and the surface.

Faced with the situation we redesigned this crossing and constructed a timber heading restricting the working space to the confines of the client’s site, making the sewer connection below ground without any disruption or need to divert existing services.
