Concrete repairs in Logan
Updated October 2026
Not every cracked driveway needs replacing, and not every repair is worth doing. The honest answer depends on what the crack is telling you, and that is a site visit rather than a phone call. We connect you with experienced, insured local concreters who assess and quote. We are a referral service, not a concreting business.
What usually goes wrong
- Hairline shrinkage cracks. Normal. Concrete shrinks as it cures and the cracks follow the path of least resistance. Cosmetic unless they open up.
- Cracks at the joints or wide of them. Often a jointing problem: too few control joints, cut too shallow, or cut too late.
- Stepped or uneven cracks. One side has moved relative to the other, which points at the base rather than the concrete.
- Sunken panels. The base under the slab has washed out or settled. The concrete may be sound and sitting on nothing.
- Spalling and flaking. The surface is breaking away, which can follow a poor finish, a hard winter of hose and sun cycles, or a surface treatment that trapped moisture.
- Lifting at tree roots. Common on established streets with mature street trees.
- Crossover breakup. The section at the kerb takes every truck that visits the street and fails first.
Where the repair work is in Logan
The older streets carry most of it. Around Woodridge, Kingston, Logan Central, Slacks Creek and Marsden there are driveways and paths that have been in the ground for fifty years, with mature trees beside them. The 1980s and 1990s belt at Springwood, Shailer Park, Daisy Hill and Cornubia is now at the age where pool surrounds and patio slabs are tired even when the driveway is fine. Around Beenleigh the mix is both at once: original cottages, 1970s and 1980s infill, and new estate on the hills behind.
Repair, resurface or replace
- Repair suits one or two cracked or sunken panels where the rest of the slab is sound. A panel can be cut out and repoured, and the join will show.
- Slab lifting and void filling can raise a sunken but otherwise sound slab by injecting under it. It is specialist work and not every contractor offers it.
- Resurfacing covers a sound slab with a spray-on or overlay system, typically around $50 to $90 per square metre. It fixes appearance, not structure. If the slab is moving, resurfacing will crack with it.
- Replacement is the answer when the cracking runs throughout, the base has failed, or the levels are no longer safe. Plain concrete typically runs about $75 to $150 per square metre laid, plus $30 to $100 per square metre to break out and cart away the old surface.
A contractor who recommends replacement on a slab that only needs two panels is not the one to use, and nor is one who promises a resurface will hold a slab that is visibly moving.
Trip hazards and the bits that are not yours
A lifted path on your own land is your problem to fix. The footpath in the road reserve and the crossover at the kerb are a different matter, because that land is Logan City Council's. If the broken section is beyond your boundary, report it to the council rather than paying to repair council land, and if your new crossover is part of the job, the council's approval is usually needed. Get the requirements from the council directly.
Costs and what to ask
Repair pricing varies too much by condition for a useful per-metre figure, which is why quotes are free. For replacements, the cost guide has the guide ranges. Three questions worth asking on any repair quote:
1. What do you think caused it, and will the repair address that cause?
2. Is the base being re-prepared, or is new concrete going back on the old base?
3. What is the joint layout, and will this panel be isolated from the ones beside it?
In Queensland, building work valued over $3,300 generally requires a QBCC licensed contractor, so ask for the licence number and check it on the QBCC register. Where a repair turns into a replacement, the approval rules sit in the Building Regulation 2021, applied by Logan City Council and private building certifiers. Before any digging, your concreter should lodge a free Before You Dig Australia (BYDA) enquiry.
Preventing the next one
Most concrete fails from underneath or at the joints, not from the mix. On a new pour, that means proper compaction of the base, mesh held up on chairs, adequate thickness for the load, control joints cut at sensible spacings and early enough, and water directed away from the slab edge rather than along it. Site classification under the Australian standard is done per block and sets what the design needs. It is also worth looking at where your downpipes discharge, because a downpipe running out beside a slab edge will quietly wash the base out from under it.

Frequently asked questions
Are hairline cracks in my driveway a problem?
Usually not. Shrinkage cracking is normal and cosmetic. Watch for cracks that widen, step, or let one side sit lower than the other, because those point at movement underneath.
Can a sunken driveway panel be lifted rather than replaced?
Sometimes. Slab lifting by injection can work where the concrete itself is sound and the void under it is the problem. Not every contractor offers it, so say up front that you want that option priced if it suits.
Is resurfacing a cheap way to fix cracks?
It hides them rather than fixing them. On a stable slab a resurface can buy years of better appearance. On a slab that is still moving, the crack will come through the new surface.
Who fixes the broken footpath outside my house?
The footpath in the road reserve and the crossover at the kerb are on Logan City Council land. Report damage there to the council rather than paying for it yourself.
