Piling a Wrap Around Home Extension Due to Drains

This piling project, completed in May 2023, was a very large, wrap-around home extension in the Ardwick area of Manchester.

Piling was required because of a large pipe running underneath the entire length of the extension’s 12.7m outer wall. The builder, who was referred to us by another contractor, booked a free site with Rhino Piling and we attended the next day.

After inspecting the site, Jonathan designed the piling scheme shown in the adjacent drawing. The scheme involved 23 x 150mmø bottom-driven mini-piles, the amount usually involved in a small new-build house. 12 were positioned conventionally, in the centre of the beam, with 11 making up multiple cross-sections across the pipe, protecting it and providing the necessary load capacity for the extension.

With the site located in the heart of Manchester, the project was only a short trip across Denton Island and down Hyde Road. Access was via an alleyway between two terraces, which wasn’t a problem for our Grundomat piling system; and over a period of 4 days, the piling team of Danny and Neel:

• Drove all of the piles to refusal at 2m
• Wrapped the pipe and other surrounding pipes in mineral wool
• Installed 42m of pre-fabricated steel ring beam
• Poured, poked, tamped and levelled 9 cubic metres of C35 concrete to complete the piled foundation
