Foundation Underpinning

Underpinning is a method of strengthening the foundation of an existing building or structure and may be required for a variety of reasons:


  • The original foundations are not strong enough
  • The use of the building has changed and stronger foundations are required
  • The properties of the soil the foundations sit on may have changed, possibly through subsidence
  • The load capacity or depth of the foundations may need to be increased to support an extension or extra storey to the existing building
  • Flood, drought or other natural causes may have caused the structure to have moved and to require re-stabilisation

Our team of professional experts will carry out thorough survey to establish exactly what needs doing.  They have a wide range of skillsets including project management, construction, structural engineering, electricians and gas engineers.

They will use their vast experience to ensure the work required is carried out quickly and efficiently with a minimum of disruption and fuss.  They will also liaise with the relevant authorities to make sure you have any required Planning Permissions or meet the statutory Building Regulations.

All our work and the materials we use are backed by a 30 year guarantee.

Our Testimonials

We have used Cellartech on many occasions now to help us with below ground solutions. From the design stages through to the installation Ian and his team have done a great job. Do not hesitate to contact Cellartech if you are after a new installation or have an existing issue with damp.

Mr Jason G

Site Manager, GTB Homes Limited

Ian and his team were a hard-working, experienced, friendly bunch.  They always turned up on time, worked hard and left the site cleaned up at the end of the day.  Ian worked hard to ensure that the build kept within our timescales and amazingly pretty much within budget.  Our experience went very smoothly with no major issues, but if we had any issues or questions Ian was always on hand to offer his advice and come up with a solution.  Ian even helped us to set up a temporary kitchen for use while the build was taking place (complete with old sink and running water!).  We’re really pleased with our finished extension and would definitely recommend Cellartech as a reliable, competitive building company.

Ian is hard working, efficient, reliable and a tidy worker. He has completed work for us on many occasions and we have never been disappointed. His work ethic is second to none and we would highly recommend him.
