Cost-effective concrete raft flooring

Because floor beams are laid out in a grid, and Polyraft pods are extra large, you benefit from more efficient use of materials and labour. Unnecessary channels are eliminated, so concrete is used in the topper, where it’s most valuable.

Create strong, stable and reliable foundations

Ground beams are 100-160mm wide (300mm wide for load-bearing walls) to ensure easy flow of concrete and eliminate complications caused by air pockets. High yield reinforced steel (HD12 or 16) adds strength to the system.

Ultra-versatile in a range of designs

Polyraft can be used in practically any site, including flat sites and sloping sites in tandem with block work. Where poor soil conditions exist, the Polyraft system complements in-ground piling techniques.

Minimise unnecessary work and waste

A concrete raft system with Polyraft offers you simplified construction processes, reduces spoil, minimises bulk excavation of sites and eliminates the need for footing excavation.

More thermal efficiency

With its excellent R-value, Polyraft provides significant thermal insulation from ground level.
