Pouring the slab is a major milestone in any build, but it is not just a matter of turning up with concrete trucks. Before any concrete is placed, there are several checks a builder needs to complete to make sure the slab performs as intended.
Getting these details right at this stage helps prevent costly issues with movement, moisture, and finishes down the track.
Before the slab is poured, any plumbing that needs to run under or through the concrete must be installed. This includes drainage lines, waste pipes, and conduits that will service bathrooms, kitchens, and laundries.
The builder checks that the plumbing is in the correct locations, at the right depths and falls, and securely supported so it will not move during the pour. Mistakes here can be very difficult and expensive to fix later.
A vapour barrier is laid under the slab to help control moisture rising through the concrete. On the Gold Coast, termite protection measures are also critical.
The builder makes sure the vapour barrier is continuous, with any overlaps taped and penetrations sealed, and that termite barriers or systems are installed in line with the engineer’s and manufacturer’s requirements.
Reinforcing steel gives the slab its strength. Before the pour, the builder confirms that the steel has been placed according to the engineer’s drawings, with correct bar sizes, spacings, laps, and supports.
Any set downs for showers or wet areas, as well as rebates for stacker doors or thresholds, are also checked at this point so floor levels will work correctly with future finishes.
Formwork defines the edges and height of the slab. The builder checks that it is straight, secure, and set to the correct levels across the entire footprint.
Falls to wet areas, garages, and external slabs are also confirmed so water drains where it should once the home is finished. Small level errors here can show up later in tiling and door thresholds.
Before concrete arrives, a final walk through is carried out to make sure everything is ready, with no loose debris, no missing reinforcement, and no damaged barriers. In many cases, an engineer or certifier will also inspect the slab preparation.
Once concrete is poured, changes are difficult and often costly. A careful pre pour checklist allows the slab to be placed with confidence, setting a solid base for the rest of the build.
