We connect you with Adelaide specialists for all types of foundation problems.
When foundations sink or stumps rot, underpinning and restumping restores stability. Our specialists use concrete underpinning, screw piles, and resin injection to relevel homes and stop further movement.
Learn more →Cracks in brickwork, concrete slabs, and walls signal foundation movement. Our specialists diagnose the cause — not just patch the crack — using epoxy injection, stitching, and underpinning where needed.
Learn more →Adelaide's reactive clay soils cause seasonal ground movement that can make foundations sink. Our specialists assess soil conditions and apply underpinning, grouting, or drainage solutions to stabilise your home.
Learn more →Leaning, cracking, or failing retaining walls need prompt structural attention. Our specialists repair, reinforce, and replace retaining walls using concrete, masonry, timber, and engineered solutions.

Vertical, horizontal, or stair-step cracks in brickwork, internal walls, or cornices — especially if they appear suddenly or are wider than 3 mm — indicate foundation movement.
Doors and windows that suddenly jam, stick, or won't latch properly can be a sign the frame has twisted due to foundation settlement or heave.
Floors that slope, bounce, or feel spongy underfoot often indicate foundation problems — especially in older Adelaide homes with timber stumps or reactive clay soils.
Gaps appearing between skirting boards and floorboards, or between walls and ceilings, can indicate the structure is shifting due to foundation movement.
Our referral service covers all of metropolitan Adelaide and surrounding areas.
Adelaide's reactive clay soils are the primary cause. These soils expand when wet and shrink when dry, creating ground movement that stresses foundations. Other causes include leaking pipes washing soil away, tree roots drawing moisture from under foundations, poor drainage, and ageing building materials — particularly in pre-1980s homes built before modern footing standards.
Costs vary significantly depending on the issue, house size, and access. Restumping a typical 3-bedroom home might range from $8,000–$20,000. Underpinning a single wall section may be $5,000–$15,000. Full foundation replacement for a large home can be $30,000–$80,000+. The only way to get an accurate price is a professional structural inspection and site-specific quote.
Underpinning strengthens or deepens existing concrete foundations by extending them to more stable soil — used for homes built on concrete slabs or strip footings. Restumping (also called reblocking) replaces deteriorated timber stumps under a suspended timber floor with new concrete or steel stumps. Many older Adelaide homes have timber stumps and need restumping; newer slab homes may need underpinning if the slab cracks or sinks.
For most foundation repairs, you need both. A structural engineer assesses the problem, identifies the cause, and specifies the repair method. A licensed builder or underpinning specialist then carries out the work to the engineer's specification. The specialists we refer work with engineers and can coordinate the entire process — from initial assessment through to completed repair.
