Concrete resurfacing and sealing in Ferntree Gully

When resurfacing makes sense

Resurfacing is cosmetic. It suits slabs that are level, drain properly and are structurally sound but look stained, faded or worn. It does not fix sunken panels, wide or moving cracks or poor falls. We inspect first and tell you honestly which applies.

Options

– grinding and honing to expose fine aggregate – crack and edge repair – spray-on or trowelled overlays with colour and pattern – epoxy or polyurethane garage floor coatings – deep cleaning and re-sealing

Cleaning and sealing

Ferntree Gully's tall trees and damp winters mean leaf stains, moss and mould on driveways and paths. Pressure cleaning, moss treatment and a fresh sealer bring back colour and make the surface safer. Penetrating sealers keep a natural look; acrylic sealers enrich colour. On driveways and steps we add anti-slip additive.

How often to re-seal

Driveways in full sun may need it every couple of years; covered patios less often. Signs it is time: water soaks in, colour looks dull, stains are harder to clean.

Whitening sealer

Cloudy or white sealer is usually caused by trapped moisture or application in damp weather. It can be treated or stripped and re-applied.

Garage floors

Grinding, crack repair and a quality coating turn a stained garage floor into an easy-clean surface. Moisture testing first prevents peeling.

Repairing a void under a garage slab

Voids under garage slabs usually come from washed-out fill, leaking pipes or poor compaction. Depending on the size, options include injecting grout, lifting the slab, or cutting out and replacing the affected section with a proper base. The cause, often water, must be fixed too.

When replacement is better

If panels have sunk, cracks are wide and moving or drainage is wrong, overlays will not last. Removing failed sections and rebuilding from a proper base is the better long-term choice.

Quotes

We inspect and quote, or recommend replacement where that is better value.

Inspecting before we recommend anything

We check for cracking patterns, sunken panels, lifted edges, ponding, drainage faults and the condition of any existing sealer or coating. Some issues are cosmetic; others point to base or drainage problems. We explain what we find and recommend the option that will last.

Choosing a sealer

Penetrating sealers soak in and leave a natural matte finish with good water repellence. Acrylic sealers sit on the surface and enhance colour, with a satin or gloss finish. Polyurethane and epoxy coatings suit garages and indoor slabs.

Timing

Sealing should be done in dry, mild weather on a clean, dry surface. In the foothills, we watch the forecast and wait for a dry spell.

Crack repair

Fine, stable cracks can be routed out and filled with a flexible sealant or a cementitious repair. Repaired cracks will still be visible, but they stop water getting under the slab. Moving cracks need the cause investigated first.

Keeping your sealer working

Sweep and hose surfaces regularly, remove leaves before they stain, and clean oil spots promptly.

Foothill ground, rain and councils

Ferntree Gully sits where the Knox plains run up into the Dandenong Ranges. Below the lawns on the lower streets you usually find heavy grey and orange clay that holds water through winter and splits open in a hot February. Higher up toward Upper Ferntree Gully, Upwey and The Basin, the soil is a stony, brown hillside clay over weathered rock, and the slopes send a surprising amount of water downhill every time it rains. Old cut-and-fill from earlier house builds adds another variable. We dig a test hole on every property, take the soft material out, rebuild with compacted crushed rock chosen for what we found, and shape the surface so water always has somewhere to go.

Inside your own boundary, most driveways, paths and patios need no permit. The crossover, kerb and council footpath always do, and that consent comes from Knox City Council for most of our area or the Shire of Yarra Ranges for Upwey and parts of Upper Ferntree Gully, Lysterfield and The Basin fringe. House slabs, large garages and many retaining walls go through a building surveyor with engineering. Bushfire and vegetation overlays affect parts of the hills. Your quote names whatever applies.

What our Ferntree Gully quotes spell out

You will not get a single number scribbled on a business card. Our written quote breaks the job into the pieces that actually drive the outcome: the area in square metres, breaking out and disposing of whatever is there now, how far down we dig, the class and depth of crushed rock, slab thickness and the steel inside it, the finish or stone blend you chose, the joint plan, each drain, pit and length of pipe, step and edge work, sealing, and any Knox or Yarra Ranges paperwork. If the site needs a line pump, a long barrow run or protection for a neighbour's driveway, that is listed too.

We keep square-metre rates off this website on purpose. In the foothills, the work hidden below the finished surface varies hugely between two blocks in the same street: one might be firm and flat, the next steep, wet and full of old fill. Pricing sight unseen means guessing, and a guess ends up either padded or short. After a visit we can price the real job.
