Around year ten, most strata committees start having the same conversation. The car park’s looking shabby, the driveways are stained, and everyone’s wondering whether it’s worth doing anything about it or just leaving it for another few years.
It’s concrete. Should be simple, right? Except when it’s common property, nothing’s ever that simple.
Why strata concrete is different
The wear patterns tell the story. In a home driveway, cars might park in slightly different spots, take various routes. In strata complexes? Everyone follows the exact same path. Same tight corner. Same speed bump. Same three-point turn spot.
You can actually see it after a few years – those wheel tracks worn into the surface where everyone takes the racing line around the bin area. Or that patch near the entry where delivery trucks always clip the corner.
Then there’s the oil. One car with a minor leak isn’t a big deal on a private driveway. But in a 50-unit complex, you’ve probably got three or four cars dripping various fluids at any given time. Add delivery vehicles, visitor cars, the occasional moving truck – it adds up fast.
What’s going on with the concrete itself
People think concrete is solid, impermeable. It’s not. It’s porous – full of microscopic holes that absorb whatever lands on them. Water, oil, rust, chemicals from car washes, salt from the roads in winter.
Once that stuff gets in, problems compound. Water freezes and expands, creating micro-cracks. Oil breaks down the binding agents that hold concrete together. Salt accelerates deterioration. What starts as surface marking becomes structural weakness.
The frustrating part is you can’t really see it happening until it’s fairly advanced. Then suddenly you’ve got spalling (those flaky patches), serious cracks, or sections that just look permanently grimy no matter how much they’re cleaned.
The maintenance dilemma
This is where committees get stuck. The options all have trade-offs:
Keep cleaning it – Pressure washing every few months makes it look better temporarily but doesn’t fix underlying issues. Like putting makeup on a problem.
Seal it – Creates a barrier against water and oil penetration. But timing matters – too early and you trap moisture, too late and you’re sealing in existing damage.
Repair the worst bits – Patching cracks and damaged sections can buy time but often looks patchy (literally) and doesn’t address why the damage happened.
Replace it – The nuclear option. Fixes everything but costs a fortune and disrupts everyone for weeks.
Making decisions without drama
Getting owners to agree on concrete work is… interesting. Some see stained concrete as character. Others want everything pristine. Most just don’t want a special levy.
What helps is actual information. Not opinions or guesses, but facts about:
- Current condition (photos help enormously)
- Likely progression if nothing’s done
- Costs of different approaches
- Disruption levels for each option
Professional assessment can be worth it here. Not to sell you something, but to give you unbiased information about what you’re actually dealing with.
The contractor maze
If you do decide to do something, finding the right contractor matters. Strata work isn’t like residential – you’re dealing with multiple owners, access issues, stages work, insurance requirements.
Every city has contractors who get this. So do give you an example without any conflict of interest I will go with a Perth company like Pressure Cleaning Perth who do concrete sealing, just so you can see what is generally offered. Sydney, Melbourne, Brisbane – they’ve all got specialists who understand strata work. The trick is finding ones who actually know what they’re doing, not just anyone with a pressure washer and an ABN.
Questions that matter: Have they done strata work before? How do they handle resident access? What happens if something goes wrong? Can they provide references from other strata complexes?
Money talk
The costs vary wildly depending on what you’re doing:
Cleaning might be a few hundred per session. Adds up if you’re doing it quarterly.
Sealing could be a few thousand for a typical car park. Sounds like a lot until you compare it to replacement costs.
Repairs depend entirely on what’s damaged. Could be hundreds, could be thousands.
Replacement? Think tens of thousands. Sometimes hundreds of thousands for larger complexes. Hence why everyone wants to avoid this option.
But there’s also the hidden costs – reduced property values from shabby common areas, potential liability if someone trips on damaged concrete, the endless committee time dealing with complaints.
The compliance consideration
Environmental regulations are getting stricter. Councils care about what’s washing off car parks into storm water. Some complexes are finding they need to address concrete contamination not because they want to, but because they have to.
Worth checking local requirements before you have a council officer explaining them to you.
Long game versus short game
Here’s what it comes down to – concrete doesn’t last forever, but how you maintain it massively affects how long it does last. Ignore it and you might get 15 years before major problems. Look after it and you might get 25-30.
The maths on that is pretty straightforward. Spending a bit on maintenance to delay massive replacement costs usually makes sense. But “usually” doesn’t mean “always” – depends on your specific situation.
What actually works
From what I’ve seen across different complexes:
Starting early works better than waiting for problems. Once concrete’s seriously damaged, options narrow and costs rise.
Regular maintenance beats sporadic panic-fixes. Boring but true.
Getting owner buy-in takes time. Start the conversation early, provide information, let people process before asking for decisions.
Document everything. Future committees will thank you for records of what’s been done and why.
Where to from here
If your complex is having the concrete conversation, you’re not alone. Every strata committee deals with this eventually. The specifics vary – coastal complexes battle salt air, inner city buildings cope with intense use, suburban townhouses might have less traffic but more weather exposure.
The right answer depends on your situation. But having the conversation early, getting proper information, and understanding your options – that’s universal.
Concrete might not be exciting strata business, but it’s visible strata business. Getting it right (whatever that means for your complex) affects everyone, every day. Worth taking seriously, even if it’s just boring old concrete.
