Whether you are building a new shed, extending a patio, or laying the groundwork for a granny flat, the quality of your concrete slab determines how that structure performs for decades to come. On the Gold Coast, where reactive clay soils, heavy seasonal rainfall, and subtropical heat are part of everyday life, slab construction needs to be done right from the ground up. Concreters Gold Coast delivers precision-poured slabs and foundations across the region for residential and light commercial projects. ## What We Offer Our slab and foundation services cover a wide range of project types and sizes: - **Shed and workshop slabs** — The most common request we receive. We pour level, reinforced slabs for Colorbond sheds, workshops, and storage buildings of all sizes. Standard shed slabs are typically 100mm thick with SL72 mesh, though we increase thickness and reinforcement for heavy equipment or vehicle storage. - **House slabs and structural foundations** — For new builds, extensions, and granny flats. We work to engineer-specified designs using 32MPa structural concrete, SL82 mesh, and additional steel reinforcement as required. Our house slabs are poured to strict tolerances and checked with laser levelling equipment. - **Patio and alfresco foundations** — Outdoor living areas need a stable, level base. We pour patio slabs with proper drainage falls and edge details that integrate with your planned pergola, deck, or outdoor kitchen. Once the base is set, you can finish with [polished concrete](/polished-concrete/) or [exposed aggregate](/exposed-aggregate-gold-coast/) for a premium look. - **Garage and carport slabs** — Reinforced slabs designed for vehicle loads, with appropriate thickness and concrete grade to handle daily use without cracking or settling. - **Extension footings** — When you are adding to an existing structure, we pour footings and slabs that tie into the existing building’s foundation system. Every slab we pour includes full sub-grade preparation. This means excavation to the correct depth, compaction of the existing soil, placement of road base material, and installation of a vapour barrier (polyethylene membrane) where required. These preparation steps are essential on the Gold Coast, where soil conditions can vary significantly across a single property. ## Our Process - **Site assessment and quoting** — We visit your property to assess the site, check soil conditions, measure the area, and discuss your project requirements. If engineer’s plans are available, we review them on-site. You receive a detailed written quote. - **Excavation and preparation** — The site is excavated to the required depth. Soil is compacted, road base is laid and compacted in layers, and a vapour barrier is placed where specified. - **Formwork** — Timber or steel formwork is set to define the slab edges, checked for level, and braced. For house slabs, edge beams and step-downs are formed according to the engineering drawings. - **Reinforcement** — Steel reinforcing mesh (SL72 or SL82) is placed on bar chairs to ensure it sits within the slab at the correct height — not resting on the ground. Additional reinforcement bars are tied in at edges, penetrations, and high-stress areas. - **Pour and finish** — Concrete is delivered and placed into the formwork. We use vibrators to eliminate air pockets and screeds to achieve a flat, even surface. Laser levels confirm accuracy across the full slab area. The surface is finished to your requirements — typically a steel trowel finish for indoor slabs or a broom finish for outdoor applications. - **Curing** — Control joints are cut within 12-24 hours to manage shrinkage cracking. We advise on curing times and procedures to ensure the slab reaches its full design strength. ## Why Choose Us for Slabs and Foundations Slab work is structural. There is no room for shortcuts, and mistakes are expensive to fix after the concrete has set. Our team approaches every slab — from a simple 3m x 3m shed pad to a full house foundation — with the same attention to preparation, reinforcement placement, and levelling accuracy. We use laser levelling on every pour, not just visual checks. This matters because even small deviations in level can cause problems with door frames, tiling, and water drainage later. On the Gold Coast, where many properties sit on reactive clay or sandy soils, the sub-grade preparation we carry out before the pour is just as important as the concrete itself. Concreters Gold Coast also coordinates effectively with other trades — builders, plumbers, electricians, and inspectors — to keep your project on schedule. We understand the sequencing of residential construction and ensure our work is completed on time and to the standard required for the next stage. ## Pricing Guide Concrete slab pricing on the Gold Coast starts from approximately **$65 per square metre** for a standard 100mm shed slab with mesh reinforcement. House slabs, structural foundations, and thicker slabs with additional reinforcement typically range from $85 to $150 per m² depending on the engineering specifications. The main factors that affect pricing are slab thickness, concrete grade (25MPa vs 32MPa), reinforcement requirements, excavation depth, site access, and whether [concrete pumping](/concrete-pumping/) is needed.

Concrete reaches initial strength in about 7 days, but full curing takes approximately 28 days. We recommend keeping vehicles off a new driveway for at least 7 days and avoiding heavy loads for the full 28-day period. Light foot traffic is usually fine after 24-48 hours depending on weather conditions. What grade of concrete do you use? We typically use 25MPa concrete for standard driveways and paths, and 32MPa for structural slabs, heavy vehicle areas, and commercial applications. The correct grade depends on the intended use, load requirements, and soil conditions at your site. Our team recommends the right grade during your consultation. Do you remove and dispose of old concrete? Yes, we handle full removal and disposal of existing concrete as part of our driveway replacement and slab services. Old concrete is broken up, loaded, and taken to an approved recycling facility. Removal costs depend on the thickness and area - we'll include this in your quote. How thick should a concrete slab be? Standard residential shed slabs are typically 100mm thick with SL72 mesh reinforcement. House slabs and structural foundations are usually 150-200mm thick with SL82 mesh and additional steel reinforcement as specified by the engineer. The correct thickness depends on the intended use, load requirements, and soil conditions at your site. ## Ready to Start Your Slabs & Foundations Project?
