The Firth RibRaft® system is becoming one of New Zealand's fastest growing residential and light commercial flooring solutions. The RibRaft system is an innovative method of concrete floor construction, offering an insulated floor with a quick, practical and efficient construction method. The system uses polystyrene pods, steel reinforcing rods, plastic spacers and Raft Mix concrete. Each of the components fit simply together, dramatically reducing labour time and costs. |

Time and Cost Savings
As the need to dig footings is eliminated, there are substantial reductions in time and labour costs. Also with construction occurring above ground and the components not affected by rain, work can often continue during wet weather. |
|
Energy Efficiency
The insulation benefits (R value) of the RibRaft floor is up to five times better than conventional floors. Also where infloor heating is used the polystyrene pods eliminate the need for further insulation.

Increased Strength
The raft design offers significantly increased strength and resistance to cracking allowing the system to be built on soils with allowable bearing pressure of 50kPa. A reinforced concrete perimeter beam and reinforced concrete ribs over the floor area, results in a slab of immense strength.

Reduced Spoil
As the floor is 'on ground' not 'in ground', the amount of excavated material on your construction site is greatly reduced.
