Concrete Driveways Sunshine Coast

New driveways, replacements and widening from Maroochydore to Sippy Downs and across the coastal strip, in plain or decorative finishes. Tell us about the job and we will get you a quote from a concreter who works your part of the Coast.

The driveway is the biggest single piece of concrete most homes on the Coast will ever have poured, and the part that decides whether it lasts happens before the truck ever arrives. Base, steel, thickness, joints and drainage falls. Get those right for the ground you are on and the slab does its job quietly for decades.

What Makes a Driveway Last on the Coast

Every cracked driveway you drive past around Maroochydore or Mooloolaba had the same concrete in it as the good ones. The difference is almost always underneath. A driveway carries a car or two every day, sometimes a boat trailer or a caravan headed for one of the parks up around Beerwah, and it sits on ground that moves. If the base was never compacted properly, if the steel ended up on the dirt instead of inside the slab, or if nobody cut joints where the concrete wanted to crack anyway, the slab will tell you about it within a couple of summers.

The Sunshine Coast makes this harder than a flat block in the suburbs. The ground swings wildly depending on where you are. Down on the coastal strip around Kawana Waters, Golden Beach and Mooloolaba you are often on loose coastal sand, which drains fast but needs proper compaction and confinement so the base does not spread under load. Back in the Blackall Range hinterland and up through the hills toward Palmwoods and Nambour you hit reactive clay and basalt soils, ground that swells when it is wet and shrinks back when it dries out. Near the Maroochy River and the Pumicestone Passage the water table sits high, which changes how a driveway has to be drained so it is not sitting in a wet base half the year. A concreter who works your area knows which of these they are standing on before the first sod is turned.

The rest of this page walks through what actually goes into a driveway on the Coast, so you can read a quote properly and ask better questions of whoever you get in.

How a Concrete Driveway Gets Built

Excavation and the base

The old surface comes out first, along with any topsoil, grass roots and soft spots. Organic material rots down and leaves voids behind, so it has to go. The crew then digs to a depth that fits the base and the slab at the finished height you want. That height matters more than people expect on the Coast, because the driveway has to meet the garage floor, the vehicular crossing at the kerb and the surrounding ground without leaving a step or a dam that ponds water.

Crushed rock goes in next and gets compacted in layers rather than all in one go, because a plate compactor can only work so much depth at a time. On the sandy coastal strip blocks the base needs proper confinement and compaction so it does not simply spread sideways. On the reactive clay behind Maroochydore the base often needs to be deeper and better drained, and that is one of the honest reasons two quotes for the same square metres can land at different numbers.

Thickness, steel and salt

A domestic driveway carrying cars is usually poured around 100mm thick. Where a boat trailer, a caravan or a heavier vehicle will sit on it regularly, or where the ground underneath is poor, it gets thicker. Reinforcing mesh goes in on bar chairs so it sits up inside the slab rather than on the ground. Steel thrown on the dirt and poured over does nothing, and you cannot see the difference once the job is finished, which is exactly why it is worth asking about.

Near the water there is one extra thing that matters here more than most places: salt. Homes close to the beach at Coolum Beach, Peregian or Marcoola, or right on the water around Golden Beach and Pelican Waters, sit in salt-laden air. Over the years that salt is what drives rust in the reinforcement and surface spalling, where the top face of the concrete flakes away. The fix is not exotic. It comes down to enough concrete cover over the steel, a mix suited to a coastal driveway, and sealing where it makes sense. A concreter who works the beachside suburbs builds that in without being asked.

Joints, falls and finish

Concrete shrinks slightly as it cures and it will crack somewhere. Control joints decide where. They get cut or tooled into the slab in a grid, roughly every couple of metres on a domestic driveway, deep enough to create a weak line that pulls the crack down out of sight. Timing matters. Saw cutting happens once the slab is hard enough to cut cleanly but before it has had a chance to crack on its own.

Falls are the other thing worth watching, and they matter even more on the low-lying blocks near the Maroochy River and Pelican Waters. The surface needs enough slope to move water away from the house and the garage rather than into them, and it has to tie in with the existing stormwater. A flat driveway holds puddles, and puddles find their way inside. Then there is the look. Plain grey concrete is the cheapest and it does the job. Washing back the surface to expose the stone gives grip on a sloped drive and copes well with wet feet, which is why it is so common around Coast pools and beach houses. Coloured and stencilled finishes sit in between. All of them still need the same base underneath.

What Drives the Price of a Driveway

We do not publish rates, because a per-square-metre number on a website is close to meaningless for concreting. Two driveways of identical size on the same street can be very different jobs. These are the things that move a quote on the Coast:

Area and shape. Square metres set the baseline. Curves, garden beds and awkward edges slow the formwork down.
Demolition. Breaking out an old slab and carting it away is a real cost, and an old driveway with steel through it takes longer to remove.
Ground conditions. Loose sand on the coastal strip and reactive clay in the hinterland each need their own base treatment.
Drainage. Low blocks near the Maroochy River and the canal estates often need extra work to keep water out of the base.
Access and slope. Steep blocks around Buderim, Nambour and Montville decide whether the concrete gets pumped or barrowed, and that changes the labour on the day.
Thickness and steel. Heavier loads and poor ground need more of both.
Finish. Plain, coloured, stencilled or exposed aggregate all sit at different points.
The vehicular crossing. Any work at the kerb where your driveway meets the road gets priced separately and needs council sign-off.

Because of all that, every driveway needs a site visit before anyone can give you a real number. Call us, describe the job, and we will get someone local out to look at it.

Sunshine Coast Specifics Worth Knowing

Your crossing needs council approval

The slab on your own land generally does not need approval, but the vehicular crossing, the strip of concrete where your driveway meets the road, is council territory. Sunshine Coast Council has its own specification for how that crossing is built (and if you are up in the Noosa Shire it is Noosa Council instead, since they are a separate council), and they want it approved before it goes in. If you are putting in a new driveway where there was not one before, or widening an existing one, sort this out early. It is the part of the job most likely to hold up a start date, and stormwater requirements can come into it on some blocks.

Sand, red soil and river-flat blocks are different jobs

A driveway at Kawana Waters on loose coastal sand, a driveway up on Buderim's deep red volcanic soil and a driveway at Palmwoods on reactive basalt clay are three different builds even at the same square metres. Sand drains freely but has to be confined and compacted so the base holds together under a car. The reactive clay and red soils in the hinterland swell and shrink with the seasons, which is hard on an under-built slab. Low-lying ground on the river flats and canal estates near the Maroochy River, the Mooloolah River and Pelican Waters can hold water in the base and often carries acid sulfate soils, so drainage falls and sometimes subsoil drainage matter more. A concreter who reads the ground correctly the first time saves you a repair later.

Steep driveways need thinking through

Plenty of Coast blocks around Buderim, Nambour, Palmwoods and Montville are steep. That affects the finish, because a smooth trowelled surface on a steep drive is slippery when it is wet, which is often around here. Exposed aggregate or a broomed finish gives grip. Access to the pour also changes on a steep or tight block, and whether the concrete gets pumped or barrowed feeds straight into the quote.

Curing in a subtropical climate

You can generally walk on a new slab within a day, but keep vehicles off for around a week while it gains strength. Your concreter will give you a firm number based on the mix, the thickness and the weather. The Sunshine Coast climate cuts both ways here. Hot, humid days can flash off the surface too fast, and the summer storm season brings sudden downpours that will mark a fresh pour, so jobs get timed around the forecast and the surface is protected and cured on the day to keep the strength in the concrete rather than lost to the air or washed off the top.

Concrete Driveway FAQs

How thick should a concrete driveway be on the Sunshine Coast?

Around 100mm is typical for a domestic driveway carrying cars. It goes thicker where a boat trailer, a caravan or a heavier vehicle sits on it regularly, or where the ground underneath is soft sand or reactive clay. Thickness works together with the base and the steel, so a concreter sets all three after looking at your block rather than picking a number off a page.

Does salt air near the beach affect my driveway?

It can. Homes close to the water at Coolum Beach, Peregian, Golden Beach or Marcoola sit in salt-laden air, and over time that salt drives rust in the reinforcement and surface spalling. The answer is enough concrete cover over the steel, a mix suited to a coastal job, and sealing where it makes sense. A concreter who works the beachside suburbs builds that in.

Do I need council approval for a driveway?

The slab on your own land generally does not need approval, but the vehicular crossing where the driveway meets the road does need Sunshine Coast Council approval, and the Council has its own specification for it. Stormwater can also come into it on some blocks. Sort the crossing early, because it is the part most likely to delay a start.

How long before I can drive on it?

You can usually walk on it within a day, but keep vehicles off for around a week while it gains strength. Your concreter will confirm a specific time based on the mix, the thickness and the weather. Driving on a slab too early is one of the few ways a homeowner can genuinely damage an otherwise good driveway.

Can I pour a new driveway over the old one?

Usually not. A thin layer of new concrete over an old slab has nothing to grip and will lift and crack, and it raises your surface level at the garage and the kerb. If the existing slab is structurally sound and you just want it to look better, resurfacing with a purpose-made overlay is worth pricing. If it has dropped or has wide moving cracks, replacement is the better call.
