K-Pods are a lightweight yet strong void former system for concrete slabs. Construction is quicker and more cost effective than traditional pours because less concrete is required. Good insulation is achieved because of the natural air pockets in EPS and the specially designed moulded cells within the K-Pod. The K-Pod system complies with all relevant Australian Building Codes and Standards. They are also suitable for use
