Concrete Slabs in Caloundra for Sheds, Garages, Granny Flats and Carports
We pour concrete slabs in Caloundra for sheds, garages, carports, granny flats, water tank pads and pool equipment bases. Every slab starts below the surface. We dig out to the right depth, lay and compact a crushed rock or road base sub-base with a plate compactor, then set up timber or steel formwork to the levels you need. Before any concrete arrives, we place a polythene vapour barrier, tie in reinforcing mesh on bar chairs and form up edge beams where the design calls for them.
Local ground conditions shape how we build. Around Pelican Waters, Golden Beach and the canal estates, the sandy soil drains fast but the water table can sit high. Some inland pockets have clay that swells after a wet summer and shrinks again in the dry. Salt air near the beaches can attack exposed steel, so we keep mesh properly covered and lifted off the ground. Summer storms also roll in quickly here, so we watch the forecast and keep plastic on hand to protect a fresh pour from heavy rain.
Say you have a new kit shed sitting in its boxes, or a builder waiting on a granny flat slab before the frame can go up. We work to your engineer's drawings or the shed supplier's slab plan, and we check set-downs, hold-down bolt positions and plumbing penetrations before we pour. If you are planning an outdoor area off the back of the house, we also build paths and patios. For runoff around slabs on tight blocks, permeable paving is worth a look.

How We Build a Concrete Slab in Caloundra
From excavation and steel to the final trowel and cure
Step 1: Site Set-Out and Excavation
We mark out the slab from your plans and check levels against the house, boundaries and fall of the block. Then we excavate to the depth the design needs and remove soft or organic soil. Stormwater and existing services get checked before we dig.
Step 2: Sub-Base Compaction and Formwork
We spread crushed rock or road base in layers and compact each one with a plate compactor, so the slab has firm, even support. Formwork goes up around the edges, braced and set to height with a laser level. Edge beam trenches are shaped at this stage.
Step 3: Vapour Barrier, Steel and Pre-Pour Checks
We lay a polythene vapour barrier with taped joints, then place reinforcing mesh and trench bars on bar chairs so the steel sits inside the concrete. Plumbing penetrations, hold-down bolt positions and set-downs get checked against the plans. Where an inspection is required, it happens before the truck is booked.
Step 4: Pour, Finish and Cure
The concrete is placed, screeded to level, bull floated and finished with a power trowel or broom, depending on how the slab will be used. We saw-cut control joints once the concrete can take it, then apply curing compound so the surface does not dry out too fast in the heat. We leave the site clean and tell you when the slab is ready for the next trade.
What a Well-Built Shed or Garage Slab Gives You
A solid, level and dry base that suits coastal Queensland conditions
A Level Base Your Shed or Building Sits Square On
When the slab is flat and true, shed frames and roller doors line up without packing and shimming. Wall frames go up faster, and doors close properly for years. Your builder or shed installer can get straight to work.
Less Cracking and Movement After Wet Seasons
Good compaction, correct steel placement and control joints help the slab handle soil that gets soaked in summer and dries out later. That means less risk of the cracking and lifting that can damage floor coverings or shed walls. Your slab stays usable without patch-ups.
A Dry Floor Under Stored Gear and Living Spaces
The vapour barrier under the slab helps stop ground moisture rising into the concrete. In humid Caloundra conditions, that means less dampness, mould and rust on whatever sits on the floor. It matters most for granny flats, workshops and garages full of tools.
Why Caloundra Builders and Owners Trust Us With Their Slabs
We Know Caloundra's Ground Conditions
We see sandy coastal blocks, high water tables near the canals and reactive clay inland. We prepare the base to suit what's actually under your slab. That's where most slab problems start or stop.
We Check Plans Before the Truck Arrives
We check hold-down bolt positions, set-downs, plumbing penetrations and edge beam sizes against your drawings before we pour. Fixing a mistake in wet concrete is costly. Catching it at the steel stage costs almost nothing.
We Work Well with Builders and Owner-Builders
We coordinate with plumbers, termite installers and certifiers so inspections happen in the right order. Owner-builders get clear answers about what's needed and when. Builders get a slab that's ready for the frame.
We Plan Around the Weather
Subtropical rain and summer heat are part of working on the Sunshine Coast. We schedule pours with the forecast in mind, carry protection on site and cure every slab properly. You get a surface that holds up.
Concrete Slab Questions from Caloundra Homeowners
Common questions answered
Do I need an engineer's design for my slab?
Habitable buildings like granny flats and extensions usually need engineer-designed slabs and certifier approval. Many shed suppliers provide a slab plan with their kit. We can work from either, and we'll tell you if what you have looks incomplete before we start.
What affects the cost of a concrete slab?
The main factors are size, thickness, edge beam design, the amount of reinforcing steel and how much excavation or fill the site needs. Access matters too, since a tight backyard may need a concrete pump. Send us your plans and a few photos of the site and we can give you a quote.
How does Caloundra's weather affect pouring a slab?
Summer storms and heavy rain can damage a fresh surface, so we watch the forecast closely and keep plastic covers on site. Hot days can dry the surface too fast, which is why we apply curing compound after finishing. During long wet spells we may need to move the pour date to protect the job.
Our block is sandy near the canals. Is that a problem?
Sandy soil drains well but can be loose, and the water table near the canals can sit high. We remove soft material, compact the sub-base in layers and follow the engineer's footing requirements. The vapour barrier also helps keep moisture from rising into the slab.
How should I look after my new slab?
Keep heavy loads, vehicles and shed frames off it until we tell you it has cured enough. Don't hose it down hard or let it bake bare in full sun during the first days if the curing layer is damaged. After that, a plain slab needs very little care beyond sweeping and cleaning up oil spills.
