Concrete Slab Construction

NZ Construction Services specialises in concrete slab construction for residential and commercial projects across New Zealand and Australia. Slabs are the most common concrete element we build, and we bring precision and efficiency to every pour.

Concrete slabs form the foundation of most modern buildings—residential house slabs, commercial floor slabs, industrial hardstands, and suspended deck slabs for multi-storey construction. Each slab type has its own engineering requirements, construction methods, and finishing standards. Our crews have the depth of experience to deliver all of them to specification, whether the project is a single house slab in Hamilton or a 5,000-square-metre warehouse floor in Perth.

We build slab systems suited to the soil conditions and structural requirements of each site. In New Zealand, that typically means ribraft or raft slabs on the clay soils of the Waikato and Auckland, and conventional slabs on the freer-draining grounds of the Bay of Plenty and Hawkes Bay. In Australia, we work with the waffle-pod and stiffened raft systems common in Perth and Brisbane, where reactive soils demand slabs designed to resist ground movement.

Quality slab construction comes down to preparation and precision: correct excavation levels, properly compacted ground, accurate steel placement, clean concrete placement without cold joints, and finishing that meets the specified tolerances. Our supervisors manage every stage of the process, from checking bearing capacity with the geotech through to final level checks on the cured slab.

What We Deliver

  • Raft and ribraft slab construction for residential builds
  • Waffle-pod and stiffened raft slabs for Australian conditions
  • Commercial and industrial floor slabs with power-float finishes
  • Suspended slab construction for multi-storey buildings
  • Post-tensioned slab installation
  • Slab construction across NZ and Australian soil types

Frequently Asked Questions

What types of concrete slabs do you build?

We build all common slab types: raft slabs, ribraft slabs, waffle-pod slabs, conventional slab-on-ground, suspended slabs, and post-tensioned slabs. The slab type for your project depends on the soil conditions, structural loads, and building design—your engineer will specify the appropriate system.

How thick should a concrete slab be?

Slab thickness depends on the application. Residential house slabs are typically 100-150mm thick with edge beams. Commercial floor slabs range from 150-200mm for standard use up to 300mm or more for heavy industrial applications. Your structural engineer specifies the thickness based on the loads the slab will carry.

Do you work in both New Zealand and Australia?

Yes. We deliver concrete slab construction across New Zealand (Hamilton, Auckland, Bay of Plenty, and Hawkes Bay) and Australia (Perth and Brisbane). Our crews adapt to the soil conditions, standards, and construction practices of each region.
