​What Is Underpinning and How Harman Contracting Services Can Help

Underpinning a house is a method used to strengthen or/and repair homes footing as well as rectify and prevent damage. This is done by building additional concrete or steel footing to stabilise and strengthen or lift an already existing building or dwelling.


When Is Underpinning Needed?

Underpinning may be necessary for a range of different reasons including:

  • Footings being constructed on loose soil or uncompacted fill
  • The original structure has changed
  • Soil changes over time 
  • Nearby construction 
  • Tree roots close to the foundations or tree removal 
  • Inadequate original structural design for the soil type 
  • Broken, Leaking pipes or poor drainage 

The first signs underpinning is required include: 

  • External cracked bricks 
  • Internal cracks in plaster 
  • Gaps between the window and walls
  • Unlevel floor 
  • Doors and windows jamming 
  • Unlevel floor 
  • Cracked flooring, slab or tiles 
  • Sinking slab or flooring
  • Cracked wall tiles

Repair Process

If you have any concerns or notice large cracks like the ones above and require underpinning we are here to help. Our office can arrange a site inspection and give you a professional quote for the repair works needed.


Structural engineering is an important part of the repair process, our team will uncover any issues & determine how much damage has occurred. We will collaborate keeping you informed on the best solution to correct the damage found and design plans for the repairs. Harman Contracting can arrange structural design plans and a soil test if required. 


Underpinning a house commonly involves digging new pier footings beside a house, which may need to include the removal of some fences, paths etc. The footings have to be out deep enough to find adequate soil to support the dwelling making it structurally sound. Once the steel is put in place & inspected, new concrete is then poured in place into the holes of the piers. Our professional underpinning team will then ensure the levelling of the dwelling, during this process any pre-existing cracks will be rectified by closing gaps and restoring the buildings structural integrity. However some cosmetic repairs might still need to be carried out.
