A poorly poured slab causes problems for years — an uneven floor, cracks running through the surface, or a base that settles and moves once the load goes on. When the ground underneath is not prepared and compacted, or the thickness and reinforcement do not suit the job, the slab is the first thing to fail. Getting it right the first time saves a lot of grief later on.
That is where we come in. We pour Auckland concrete slabs for homes, sheds, garages, sleep-outs, and outdoor areas, and we do the groundwork properly. From excavation and hardfill through to reinforcement, boxing, the pour, and a controlled cure, we handle the whole process so you end up with a flat, level, hard-wearing slab.

Concrete Slabs We Pour in Auckland
House and Floor Slabs
We pour flat, level concrete slabs for new homes, extensions, and internal floors. Each slab is set out accurately, screeded to the correct fall, floated to a smooth finish, and cured properly so you get a solid, even surface ready for framing, flooring, or tiling.
Shed and Garage Slabs
We lay hard-wearing slabs for garages, workshops, and sheds that need to take vehicle weight, tools, and machinery. We form up the edges, set the thickness to suit the use, and finish with a smooth or broom surface that stays flat and easy to keep clean.
Sleep-Out and Granny-Flat Slabs
Planning a sleep-out, granny flat, or minor dwelling? We pour slabs sized to the building footprint with the right thickness, edge thickenings, and service penetrations set out in advance, giving your builder a clean, accurate base to work from.
Patio and Outdoor Slabs
We pour outdoor slabs for patios, entertaining areas, bin pads, and spa or shed bases. We plan the fall so water runs away from the house, and finish the surface with a texture that suits the space and stays comfortable underfoot.
Reinforced Slabs for Heavy Loads
For slabs carrying heavier loads — machinery, storage, or frequent vehicle traffic — we build up the thickness and add steel mesh or bar reinforcement. This helps spread the load, control cracking, and keep the slab performing well for years.
Base Prep and Site Works
A good slab starts underneath it. We handle excavation, levelling, hardfill, compaction, and boxing before any concrete is poured. We can also lay a damp-proof membrane and set out formwork so the finished slab sits level, stable, and true to plan.
Why Choose Our Concrete Slab Team in Auckland
Experienced Slab Crews
Our team pours slabs across Auckland every week, so we understand local ground conditions, drainage, access, and what it takes to get a flat, level result the first time.
Correct Thickness and Reinforcement
We match slab thickness and steel to the intended use, whether it is a light garden shed base or a slab that needs to carry vehicles and heavy loads, so the finished slab suits the job.
Thorough Base Preparation
We take the time to excavate, level, compact, and prepare the ground properly. A well-compacted base reduces the risk of settling, movement, and cracking down the track.
Level, True Finishes
We set out formwork carefully, screed to consistent levels, and float the surface to a clean finish so your slab is flat and ready for whatever goes on top of it.
Proper Curing
We do not rush the cure. Controlled curing helps the slab reach its strength and reduces surface cracking, so you get a durable base that lasts.
Clear Quotes and Tidy Sites
We provide straightforward, itemised quotes, keep you updated as the work progresses, and clean up the site once the pour is complete and finished.
Concrete Slab FAQs
Answers to common questions about concrete slabs in Auckland — costs, thickness, reinforcement, curing times, and site preparation.
The cost of a concrete slab depends on its size, thickness, the reinforcement required, site access, ground conditions, and how much excavation and base preparation is needed. A small garden shed base is far more affordable than a large house slab or a reinforced slab built to carry heavy loads. Extra work such as removing an old slab, importing hardfill, or improving drainage will also affect the price. The most accurate way to get a figure is through an on-site assessment and a detailed, itemised quote based on your project.
The right thickness depends on what the slab needs to support. A typical residential floor or shed slab is often around 100mm, while garage slabs and areas carrying vehicles or heavier loads are usually thicker, with edge thickenings around the perimeter. Slabs for machinery or frequent heavy traffic may be thicker again and more heavily reinforced. During our assessment we recommend a thickness suited to the intended use, the ground conditions, and any engineering or council requirements for your site.
Most slabs benefit from reinforcement. Steel mesh is commonly used in residential slabs to help control cracking and hold the slab together as it cures and moves with temperature changes. Slabs carrying heavier loads may need reinforcing bar as well as, or instead of, mesh, along with a greater thickness. The reinforcement is placed correctly within the slab so it works as intended. We advise on the right reinforcement for your slab based on its use, size, and any engineering requirements.
A concrete slab starts hardening within hours, but it keeps gaining strength for weeks. Light foot traffic is often possible after a day or two, but building work generally waits until the slab has cured enough to take the load — commonly about seven days for lighter framing, with concrete continuing to strengthen for around twenty-eight days. The exact timeframe depends on the weather, slab thickness, and concrete mix. We will give you specific aftercare advice and let you know when your slab is ready to build on.
Good preparation is what makes a slab last. Before pouring, we excavate to the right depth, remove unsuitable material, and bring the ground to level. We then place and compact hardfill to create a stable base, lay a damp-proof membrane where required, and set up formwork to the correct levels and falls. Reinforcement is positioned before the pour. Taking care with this groundwork helps prevent settling, moisture problems, and cracking, so the finished slab stays flat, stable, and durable.
