A garage slab on the Gold Coast has to do more than hold up a couple of cars. Owners here regularly park boats, jet skis, trailers and 4WDs on the same pad, and the slab has to live with salt air, summer humidity and sandy or reactive soils depending on which side of the M1 you sit. We pour garage slabs from Coolangatta up to Pimpama and west into the hinterland, and every one is sized and detailed for what is actually going to live on it.

What Makes Gold Coast Garage Slabs Different

The Gold Coast is not one market. A waterfront garage at Sovereign Islands has nothing in common with a townhouse garage at Robina or a workshop in Currumbin Valley. The two things that tie almost every Gold Coast slab together are the climate — warm, humid, and salt-laden close to the beach — and the lifestyle, which usually means a boat or jet ski lives next to the car. Both of these push us to over-spec rather than under-spec the slab.

Coastal Vehicle Storage and Salt Air Protection

Salt air does not eat concrete itself, but it attacks the steel reinforcement inside the slab. Once that steel rusts it expands and cracks the concrete from the inside out. On any garage within a few kilometres of the beach — Surfers Paradise, Broadbeach, Mermaid Beach, Burleigh Heads, Palm Beach, Currumbin, Tugun and Coolangatta — we treat the slab as exposure class B1 or B2:

Boat, Jet Ski and Trailer Garages

Standard double garages are 6m wide by about 5.5m to 6m deep. That is fine for two cars. The moment a boat trailer joins the family, those numbers stop working. The boat needs length, the trailer needs a flat run-out, and you still need to walk around it. We commonly build:

We also detail the slab for the actual trailer wheels — a slightly thicker zone or saw-cut control joint where the jockey wheel sits, and a smooth run from the apron through the door so you are not lifting over a step every time you launch.

Older Beachside Garage Replacements

Plenty of homes in Burleigh, Mermaid, Palm Beach and Tugun are working off original 1970s and 1980s slabs that have spalled, cracked or sunk on one corner. Replacing the slab on these blocks is rarely a simple pour. The original was usually thin, lightly reinforced, and the surrounding ground has shifted around it. We break out the old pad, re-grade the base, lift the levels to suit the current door height, and pour a new slab to modern coastal spec. Most of these jobs also include re-doing the apron so water sheds away from the house rather than back into the garage.

Premium Waterfront Properties

At Hope Island, Sanctuary Cove, Sovereign Islands and Paradise Point we are usually working alongside a builder, a landscaper or both. The brief on these jobs is finish-first: tight control of slab levels for polished or honed finishes, perfectly straight saw-cuts, no surface markings, and slabs that line up exactly with stone tile thresholds inside the home. We pour with a longer slump, finish in stages to suit the weather, and protect the surface aggressively while it cures. Drainage on the canal side gets extra attention — the last thing you want is a king-tide sitting against an unsealed slab edge.

High-Density Townhouses and New Estates

Robina, Varsity Lakes, Carrara, Nerang, Surfers Paradise townhouses and the newer estates at Coomera, Pimpama, Helensvale, Oxenford and Pacific Pines all share one thing — tight access. The truck cannot back up to the slab, the wheelbarrow run is long, and there is usually a fence to negotiate. We work small pumps, line pumps and barrow runs into the quote rather than getting halfway through the day and finding out the truck cannot get to the pour. Single garage slabs at 3m x 5.5m and detached doubles at 6m x 6m are the bread and butter on these blocks.

Hinterland Workshop Garages

West of the M1 the soil changes from sand to reactive clay, and the projects change with it. Tallebudgera Valley, Currumbin Valley, Mount Tamborine, Worongary and Bonogin owners typically want bigger slabs — workshop garages for boats, 4WDs, dirt bikes and project cars. Sizes of 7m x 9m, 8m x 10m and even larger are common. Reactive clay means we focus on moisture control, a stiffer mesh layout (SL82 is the standard rather than the exception), and a slab edge that is properly thickened to handle ground movement. Slope on these blocks usually means a gentle fall across the slab rather than a stepped pour.

Cyclone and Tie-Down Considerations

The Gold Coast sits in wind region B and the garage structure on top of the slab needs to be tied down accordingly. Where the garage is pre-engineered (a kit garage or shed-style garage) we pour the slab to the manufacturer's footing schedule — usually thickened edges or pad footings under each post position with cast-in chemical anchors or hold-down bolts. We work from the structural drawings rather than guessing, and we set the bolts before the concrete goes off rather than drilling and fixing later.

Finishes for Indoor-Outdoor Garage Living

A lot of Gold Coast garages double as a second living area — bar fridge, surfboards on the wall, doors open to the yard. The finish matters. Here is how we usually steer the conversation:
