What is Underpinning
Footings Underpinning; Is lifting and stabilizing settled, sunken, subsided, failed, footings by digging under the failed footing to required depth and pouring concrete under the footing to transfer building loads into deeper, better soil in terms of bearing capacity and soil reactivity to changes in moisture content and effect of nearby trees.
Types of footings we underpin:
- Reinforced concrete strip footings
- Blue stone footings
- Rubble footings
- Brick footings
- Raft and waffle pod concrete slabs
- Underpinning and Floor Re-Levelling Specialists
Licensed & Insured
Underpinning is used too when the existing footing is or will be undermined because of new or proposed nearby building, extension, swimming pool, trenches for pipes and service connections.
Most of the footings we underpin we lift using hydraulic jacks to required level to reduce cracks on the walls and improve floor level.
Vast majority of footings we underpin are reinforced concrete strip footings, because most of the properties has this type of footings. We also come across blue stone, rubble, and brick footings too for buildings build over 80 years ago. We also underpin concrete raft and waffle pod slabs too.
