London Elite Traders Ltd offer two types of underpinning methods; Traditional Underpinning and Piled Underpinning.
Building regulations approval is normally required if you want to underpin an existing foundation. A structural design for the underpinning, including details of the construction process, will generally be needed. Before any major underpinning work starts, a trial hole will be dug next to the existing foundation for a structural engineer or surveyor to assess exactly what is required.
A typical method is for short sections of underpinning to be separately installed; depending on how much of the fountain needs underpinning, it is sometimes possible to install more than one section at a time.
Before each section of underpinning is concreted, it will normally be inspected by a design engineer and a building control surveyor. A sand and cement packing will usually be packed between the existing foundation and the underpinning to ensure support and fill in any voids; this will also be inspected by a engineer or a building control surveyor.
We work closely with structural engineers, architects, private home owners, building contractors, insurance companies and local Authorities.
