CLICK TO CALL GET A QUOTEConcrete underpinning is a process used to strengthen and stabilise the foundations of a building or structure. It requires excavating soil underneath the foundations before replacing it with concrete and any additional supporting materials. This prevents further movement or collapse of the structure.
All underpinning work from JPD Developments starts with a site visit to determine the project's demands. We take care of the job from start to finish for your pleasure and convenience. We will provide a comprehensive quote for this service so you know exactly what you’re paying for.
Before we start our professional underpinning work on your property in Bromley, Bexley, Sevenoaks, Surrey or the surrounding areas, we check for any services that could be damaged by the underpinning. An engineer and a building inspector will inspect the bottom of the foundations to determine whether it’s safe to carry out the underpinning on them. Once approved, any projecting portions of the existing footings are carefully cut off where necessary, and the underside of the footings is cleaned of any dirt, soil or loose materials before underpinning.
The underpinning is carried out in short sections of approximately 1 metre in length. It uses a 1:2:4 mix of concrete and is cast to the required widths unless otherwise specified by the engineer. Excavation and concreting of any underpinning shall be done on the same day. However, it won’t be started until at least 48 hours after any adjacent sections of work are completed.
The mass concrete is stopped off 75mm underneath the existing footing. The final pinning up over the whole of the footing uses a 1:3 mix of cement to sharp sand and dry pack mortar and is well rammed in 24 hours following the pouring of the mass concrete. The sides of the previous underpinning bays are roughened or keyed.
Our piling contractors will keep a record of the specifications of your concrete underpinning. This will include:
