One sure sign that your home may require underpinning is when you can see cracks in your brickwork or internal walls. This is caused from movement in certain areas of the existing foundation while other areas may not be moving thus parts of your walls will separate and leave gaps.

Once the underpinning process is complete and the concrete has had time to settle, which we normally allow a minimum of 7 days, we will come back and jack your building where we have completed the underpinning.









This is done by placing hydraulic jacks between the new footings we have created and your existing footings. These jacks have the capability of moving a 50 tonne capacity. We do not jack from one pin alone e.g. if we have done 10 new pins, we will use 10 jacks for the process therefore creating an equal and smooth lift.

We always attempt to jack your home or building back to its original level, trying to close up all the cracks but sometimes this is not always possible as your original footings may be weak and brittle and may not be able to handle the pressure from the new stable footings we have created.

Once your house or building is back to original level or as close as possible to that level, the jacks are removed and steel plates are inserted into the void for support and the void is then packed with dry pack grout to stop any movement between the old footing and the new pin.
