Underpinning Adelaide

Toby is a second-generation stonemason, and has been working in the building industry for 20 years. He started as a brick and block laying apprentice, went on to specialise in heritage stone work and restoration. Through his work restoring heritage buildings, he found a substantial number of significant cracks were due to aging, or poorly constructed foundations, and or soil movement. He then went on to further specialise in structural underpinning.  The method of concrete structural underpinning he offers, enables him to guarantee permanent crack repair and the structural stability of his restoration works.

Underpinning is the process of constructing new secure foundation anchor points for existing buildings, to relevel and stabilise the home or commercial premises.  

Now specialising in structural underpinning exclusively for the past 10 years, Toby and his team from Northern Underpinning have reinstated structural integrity to hundreds of buildings, both commercial and residential across South Australia. Based in the Southern Barossa Valley, Northern Underpinning, services city, metro and rural South Australia, with good old-fashioned quality customer service, and a tried and proven method of concrete (not chemical) underpinning, to give reliably solid results.  Our customers enjoy long term peace of mind, and structural stability, knowing that their job is done properly by a team who pride themselves on the quality of their work.  


How do I know if my property needs underpinning?

Indications your property may require underpinning, reoccurring cracking. Sticky or jamming doors and or window, this can indicate foundation sinking.  Cornice movement or cornice collapse caused by leaning walls.


What’s the process?
Underpinning requires major structural building works, including excavating and removing soil, hydraulic elevation/ releveling of the building and concrete reinforcing. This is done by a skilled and experienced team, using specialised equipment and knowledge.


How long will my underpinning job take?

The timeline varies depending on the number of underpin points required, the site accessibility and the soil composition. Smaller residential jobs can be as fast as 3 days in ideal conditions, and larger scale or difficult sites can take up to two weeks or more. An average underpinning job can generally be complete within a week.


How many underpins will I need?
 It depends on the level of damage to your existing structure and foundation. A site evaluation will provide you with a clear outline of how many underpins are needed to restore the structural integrity of your property.


Do we need to vacate the property while works take place?
Not usually. This is assessed on a job by job basis and can be discussed at the time of your meeting with Toby.


Pricing. How much does it cost?
The cost varies, depending on the number of underpinning anchor points required, also on your site location and site accessibility. Underpinning requires major structural building works, including excavating and removing soil, hydraulic elevation/ releveling of the building and concrete reinforcing. It is significant structural work and the cost start from $4400, for a single anchor point. The cost of an average residential underpinning job is generally in the vicinity of $10,000 –  $22,000. It can be significantly more for large and or difficult jobs, or less where fewer underpins are needed. A site inspection will give you a clear picture of the work required to reinstate the structural integrity of your property and provide you with a customised quote.


How soon can you start?

Generally, within 4-6 weeks from the time your job is booked and confirmed


Help, my wall’s about to fall over!?

Sometimes due to extensive rain or soil movement a wall can become significantly unstable, even overnight. It can be necessary to take emergency measures to manually acro prop the wall to stabilise the building until we can get there to underpin it. If you require emergency assistance for a wall on the verge of collapse please call Toby directly 0421 750 410.
