Concrete frequently asked questions
Questions are grouped by topic below. If you can't find what you're looking for, get in touch directly.
Cost
Every job is different. The total cost depends mostly on how much surface preparation we have to do. Grinding down uneven joins or stripping a failing old sealer also adds to the on-site hours before the job can be finished properly.

Suitability
If your driveway's concrete is still sound and just needs a refresh, cleaning and sealing is usually worth considering. We check the condition first so we're not sealing over problems that need dealing with another way.
Cracks
It depends on the crack. A small, stable crack in otherwise sound concrete is a different situation from one that's still moving. If the crack is still opening up, that points to something happening in the slab below, and it's worth having it assessed before deciding what's realistic — rather than assuming a quick patch will hold.

Damage
This pitting is called spalling. It's usually a sign the concrete mix had too much water in it when poured, or dried out too quickly in the sun, leaving the top skin soft and weak. Whether it's worth addressing depends on how far it's progressed — localised spalling in an otherwise sound slab is a different situation to widespread flaking.
Driveways
Often, yes. Slip-resistant grit can be mixed into a sealer coat to help tyre grip on steep driveways, which matters more once the surface gets wet. No finish makes a wet surface completely slip-proof, so sensible driving still applies on a steep grade.
Cleaning
Professional pressure cleaning is set up to remove ingrained grease, grime and organic growth from the concrete's surface more thoroughly than a quick hose-off. The exact approach still depends on the surface condition and what's caused the staining.
Sealing
Concrete is porous — it absorbs water and grease more than a sealed surface would. A sealer reduces how much soaks into those pores and helps the slab deal with everyday Queensland sun and rain, without making the concrete impervious.

Resealing
A simple check: pour a cup of water on the surface. If it beads up, the sealer's likely still doing its job. If the concrete absorbs it and darkens within a few minutes, that's a sign the protection has worn thin and it's worth having a fresh coat considered.
Timing
It depends mostly on the weather and how much surface preparation is needed first. Atlas can give you a realistic timeframe once the job's been assessed in person.

Curing
Sealer cures through a chemical reaction that locks the polymers together. This process takes time to reach a workable hardness and resist everyday oil and hot car tyres.

Maintenance
Maintenance is fairly straightforward. Keep the surface swept and hose off loose dirt regularly. Wash away wet leaves reasonably promptly so they don't leave organic staining, and avoid harsh solvents or metal-edged tools that could scratch the sealer.
Slip Resistance
A smooth surface can be slippery when wet, much like smooth concrete generally is. We can mix slip-resistant grains into a sealer coat to add grip for tyres and bare feet, but no finish makes a wet surface completely slip-proof — sensible footwear still matters.
