- Preparation. Excavation, fill and compaction.
- Formwork. Edge shutters, or full formwork and props for suspended slabs.
- Damp-proofing. DPM under ground slabs.
- Reinforcement. Mesh or bar steel to specification.
- Concrete. Ready-mix supply, pump, pour and finish.
- Curing. Keeping the slab moist so it reaches strength.
Suitable Projects
House floors, extensions, garages, patios, workshops, carports, water tank bases and outbuildings. Larger commercial and warehouse floors are covered under Industrial Concrete Slabs.
Available Systems
- Surface bed. A ground-bearing slab inside strip footings.
- Raft slab. A slab and foundation in one. See Raft Foundations.
- Rib and block. Precast beams with blocks and a topping, for upper floors.
- In-situ suspended slab. Formed and poured in place, for spans and cantilevers.
How the System Is Chosen
Ground conditions, the span, the loads and the finish you want set the slab type. Suspended slabs need an engineer.
Project Process
- Plans. Drawings or a clear description of size and use.
- Quote. Contractors measure and price.
- Prepare. Excavate, compact and form up.
- Steel. Mesh or bars fixed and inspected.
- Pour. Concrete placed and finished.

Concrete Slabs FAQs
How much does a concrete slab cost per m²?
As a ballpark, R500 to R850 per m² for a ground surface bed and R1,400 to R2,500 per m² for an in-situ suspended slab, excluding VAT.
How long before I can walk on a new slab?
Usually after a day or two. Heavy loads and building on top need longer, as advised by the engineer or contractor.
Do I need mesh in my slab?
Most slabs are reinforced. The specification comes from the plans or engineer.
Can a slab be poured in the rain?
Contractors avoid it, as rain damages the surface. Pours are rescheduled for dry days.
Should I use a concrete pump?
Where the truck cannot reach the slab, a pump is quicker and gives a better pour than barrowing.
