Concrete slabsthe part you only get one shot at

The slab is structural, not just a floor

A shed slab is engineered. Thickness, reinforcement, edge thickening and footing design all come from the engineering for your building on your site — the wind classification, the span, the height and the soil conditions. The frame bolts down into it, and in a wind event the slab is what stops the building lifting.

That is why we do not treat the slab as a separate trade you organise yourself. It is designed with the building, and the anchor positions have to match the frame exactly.

• Thickness and reinforcement set by the engineering, not a standard detail
• Edge beams and footings sized for the wind uplift on your site
• Anchor positions set out to the frame
• Finished floor level worked against site drainage and access

Site conditions around the Wide Bay

Soil varies enormously across the region — reactive clays in some areas, sand closer to the coast, and rock in parts of the Burnett. Soil classification affects footing design, and it is one of the reasons we ask for your full site address on the quote form. A slab designed for a stable site and poured on a reactive one is a problem that shows up as cracking a few years later.

Fall, drainage and where the water goes in a heavy wet season are part of the same conversation. Getting the finished floor level right keeps stormwater out of the shed.

Why Boral, Holcim and Mansell

Boral, Holcim and Mansell Premix are established concrete suppliers with local batching plants serving Bundaberg and the Wide Bay. That means consistent mix design and reliable delivery on pour day — and on a slab pour, timing is everything. Mansell Premix operates a batching plant right here in Bundaberg, so concrete is fresh and on time.

Because all three are established local operations, we can schedule pours with confidence and keep your build on the timeline we quoted, with backup supply if one plant is delayed.
