This revolutionary insulated slab system removes timely and wasteful boxing techniques, while providing the most insulated slab system on the market today. Simply compact the ground, level and set polystyrene profiles out. After reinforcing is added you are then ready to pour in a fraction of the time taken by conventional methods. Can be used in conjunction with any building system. 

Following the Christchurch earthquakes New Zealand's Department of Building and Housing has officially recommended use of Raft Slabs as a preferred alternative to traditional foundation construction. MAXRaft© is the only FULLY insulated slab available on the market today - ZERO thermal bridging.

Thanks to a lot of media coverage about healthy homes, insulating a house properly is high on the agenda of many house builders. That's because the benefits of doing so are huge and everlasting.

It can't be overstated just how important it is to insulate your entire home, not just the walls and roof. Heat loss in a home happens in a variety of different places including 15% through the slab the house sits on. This is why it makes sense to insulate your entire home, especially if you want to remain comfortable, healthy and save on energy bills.

Start by insulating your home the right way

The concrete slab your home sits on is often the last consideration when trying to improve thermal efficiencies and home comforts. When you insulate everything else in the house, it makes no sense to ignore the floor beneath you.

MAXRaft is all about creating comfortable and healthy year round living temperatures in your home through foundation insulation. In fact we offer New Zealand's only fully insulated concrete slab to increase the performance of your home from the ground up.

MAXRaft provides the same structural integrity as waffle floors, while providing superior insulation. We use polystyrene, which is an ideal material when insulating your home, and it's manufactured and precut in our factory before sending materials to the building site where everything fits together quickly and efficiently like a jigsaw puzzle. The benefit of this approach is that we control waste and recycle materials.

The main benefits of MAXRaft:

  • Warm, sustainable and healthy living
  • Engineered specifically for your section
  • Maximum energy efficiency
  • Thermal break insulation
  • Cost savings
  • HOMESTAR™ rating
  • Home comfort
  • Health
  • Excellent aesthetics
  • Seismic strength
  • Underfloor heating friendly
  • Exposed concrete floors
  • Achieves an R Value of approximately R4 according to floor design.

We work closely with architects, engineers and builders and can handle almost everything for you, or prepare your insulated foundation for your builder to install on site.

Your home's slab cannot be replaced so when building make an informed decision and choose a fully insulated MAXRaft® concrete slab to improve your home's comfort and energy use.
