Our slabs are designed to handle Sydney's varying soil conditions, weather extremes, and modern building loads. A proper concrete house slab not only improves durability but also boosts energy efficiency and protects your home from pests, movement, and moisture.
When Should You Start Thinking About Concrete Slabs?
Right from the start. The house slab is one of the very first stages in any residential construction project. Without the right slab, your build can be delayed, misaligned, or structurally compromised. That’s why it's essential to work with experienced concreters in Sydney who understand terrain, soil types, and engineering requirements.
Types of Concrete House Slabs We Offer
Raft Slabs
Best suited for unstable soil or sloping blocks, raft slabs use integrated steel reinforcement and deeper edge beams. These slabs reduce the risk of movement and offer superior crack resistance—perfect for Sydney’s challenging terrains.
Waffle Slabs
Cost-effective and ideal for stable soil, waffle slabs feature a grid of internal beams. These slabs are quicker to install and offer thermal insulation benefits, though they require careful site assessment to prevent future issues.Our team will assess your site and recommend the best solution for your land, structure, and design.
