Is your home suffering from cracked brickwork, windows that won't close, a sagging roofline or uneven floors? If so, your home may need underpinning services, and Underpinning Resources is the team to call.

How do I know if my home needs underpinning?

You may notice cracking in the mortar joints of your brick or blockwork, or in internal plaster. Windows and doors may start to stick or jam, or you may notice your floors have become uneven. These problems might seem small, but they can be symptoms of a much deeper problem in the very foundations of your home.

What is subsidence?

Subsidence occurs when the foundations of your house move or sink over a period of time. Many things can cause subsidence, such as sliding surface layers, extensions and additions to your home, or excessive vibrations, but most usually it's caused by fluctuations in the moisture content of the foundations and soils beneath your home over a long period. Buildings in areas which experience extended periods of rain or drought, particularly ones built on soils with a reactive clay content, are particularly susceptible to subsidence, movement, heave and land slip.

If you notice any of the symptoms mentioned above, call Underpinning Resources. We are Tasmania's underpinning experts with the experience and knowledge to spot and identify problems and find the solutions. We offer on-site consultations, expert advice and free, no-obligation quotes. We will assess the extent of the issue and construct a plan of action, talking customers through every step of the underpinning process and the work necessary to make your home safe and sound again. 

Our Underpinning Process

Underpinning Resources offers comprehensive underpinning services. We will complete all necessary paperwork and provide you with a contract to read and sign. This is all then submitted to your local Council and/or engineer and, when we receive a permit or notice of assessment, we will contact you to arrange a suitable date of commencement for the work to begin.


During the underpinning process, we excavate at key points, determined by expert analysis of the movement of your building. Once we reach a suitable depth (at least 1.8 metres below ground level), we fill these excavations with concrete to create a base on which to jack and prop your footings using heavy-duty hydraulic jacks. Once your house is underpinned and everything is satisfactory and meets our high standards, we backfill the excavations, re-point any brickwork that requires it and return any paths, lawns and gardens to their original condition.

Pier replacement and house levelling

Two black rounded rectangles on a white background, one wide and one small.

Pier replacement and house levelling involves raising piers that have sunk due to soil deterioration. This happens for many reasons, including subsidence, excessive moisture or water pooling, inadequate drainage or excessive drying in clay foundations.


The original piers may simply be inadequate or may have deteriorated over time, and sometimes there are no footings at all, which is a common cause of sagging floors. Underpinning Resources provides a quote to replace as many or as few of the piers as required, with new concrete, brick or screw adjustable piers.

Underpinning Resources provides accurate, no-obligation quotes for all of our services. We differ from most other businesses because our quote is fixed. This means we give you a price for the completed project and that is what you will pay. With Underpinning Resources, the charge to you never spirals with costly additions. Sometimes we might find the underpins require extra depth or we may encounter plumbing which needs to be repaired, but these challenges will never add to the price on our quote. Underpinning Resources gives you the best quote, first time, every time.
