Expert Solutions for Every Foundation Need

We know our foundations, and we
understand that one size doesn’t fit all!

At Rapid Slabs & Precast, we specialise in the complex and work with a wide range of foundation solutions tailored to meet the specific needs of every project. From conventional slabs to complex, engineered foundations, we’ll work with you to determine the best approach for your build, whether it’s a small residential job or a large commercial project. With an abundance of industry experience, our team has the expertise to deliver a foundation that’s right every time.

We’re proud to offer various advanced foundation systems that provide flexibility, strength, and efficiency, allowing us to adapt to unique site conditions and project demands. Foundation systems we work with include (but not limited to):

Conventional foundation

A traditional concrete foundation system used in residential and commercial construction. It typically consists of reinforced concrete footings generally dug into the ground and a slab or strip footings with concrete walls.

RibRaft

Is a popular above-ground foundation system in New Zealand that uses polystyrene (void former) pods and steel reinforcement rods. The pods reduce the amount of concrete required while evenly distributing the load, and the steel rods strengthen the poured concrete for added structural integrity.

Xpod

A similar system to ribraft, but instead, uses pre-formed plastic pods 
(void former) placed under a concrete slab to create a lightweight, energy-efficient foundation.

Cupolex Ecodome

An eco-friendly concrete floor system that uses plastic, dome-shaped forms to create voids within a concrete slab. By placing concrete over these modular forms, it creates a strong, efficient waffle raft slab that uses less concrete while maintaining excellent load-bearing strength. This design improves under-slab airflow for moisture control and insulation, making it a sustainable, durable choice for projects aiming to lower their environmental impact.

Biax 500

A sustainable reinforced concrete foundation designed to be easily re-levelled if needed. It’s a ribbed slab that works well on soils that tend to shift, like areas with liquefaction risk or expansive soils. This system provides a solid, stable base for structures, whether they need deeper support with piles or just a shallow foundation.

Edge Insulation

Edge insulation is used around the perimeter of a concrete foundation to reduce heat loss and improve energy efficiency. It helps create a thermal barrier between the slab and the outside ground, making it an important part of meeting modern building standards. We offer a range of edge insulation options to suit different foundation types and project needs. These include (but not limited to):

  • QuickEdge 
  • Firth Hot Edge
  • Duratherm

At Rapid Slabs & Precast, we believe that strong relationships are key to a successful project. From the initial consultation to project completion, we work closely with you every step of the way to ensure your foundation is built to the highest standards. Our focus is on understanding your needs, delivering quality results, and making sure your project runs smoothly from start to finish.
