Raft Slabs Melbourne
A single, thickened reinforced slab that spreads building load evenly, suited to sites with more stable soil conditions.
Raft Slab Construction Across Melbourne
A raft slab is a single, continuously reinforced concrete slab poured as one thickened mass, designed to spread the load of the building evenly across the ground beneath it. Compared with a waffle slab, a raft slab is generally a simpler, more economical design, and suits sites with more consistent, less reactive soil where a soil report supports this approach.
HPL Construction builds raft slabs for homeowners, builders and developers across Melbourne, with reinforcement, concrete supply, labour, the slab concrete pump, site cut, base preparation and trench depth up to 500 mm all included as standard.
Standard Raft Slab Specifications
We build raft slabs at a standard 110 mm depth, with a 140 mm option available where additional slab stiffness is specified. As with our waffle slabs, bored piers can be incorporated where a soil report identifies the need for deeper footings at specific points across the slab.
Our Raft Slab Process
We begin with a site inspection and review of your soil report, then complete site cut and base preparation, install reinforcement, and pour and finish the slab using a concrete pump. Our team oversees the entire project from initial consultation through to a completed, inspected slab.

Frequently Asked Questions
What soil conditions suit a raft slab?
Raft slabs generally suit sites with more stable, less reactive soil. A geotechnical soil report will confirm whether a raft slab or an alternative like a waffle slab is the right approach for your site.
Is a raft slab cheaper than a waffle slab?
Raft slabs are often a more cost-effective option where soil conditions allow, since the design is generally simpler than a waffle slab. Actual cost depends on your specific project.
What is included in trench depth up to 500 mm?
Our standard raft slab estimate includes trench excavation up to 500 mm as part of the footing preparation. Deeper trenching required by engineering drawings is confirmed and priced separately.
Can I get an instant price estimate?
Yes. Our free Raft Slab Calculator gives an instant cost estimate based on your project area, slab thickness and whether bored piers are required.
