Insulated concrete, Christchurch.
A slab you will live on for decades either leaks heat forever or holds it. The difference is decided on pour day, and it is the cheapest it will ever be right then.
The insulation goes in with the pour.
The concrete side of the business covers what a foundation crew should: the slabs themselves, the footings, the finishing. The insulated side is where the difference shows. Edge insulation and under-slab systems built into the pour, not retrofitted around it.
Insulating at pour time costs a fraction of chasing warmth later, and on a new build it is the difference between a floor you avoid in winter and one the house is heated through.
- Edge insulation detailed into the boxing, not glued on after.
- Under-slab insulation options priced with the quote.
- Underfloor heating coordinated into the pour, where there is any.
- The same coordination spine as every job: trades, council, sign-off.
A cold slab is a permanent bill.
The insulated version of a foundation costs the least it will ever cost on the morning of the pour, and nothing after that morning can add it.
Insulation gets left to the next trade.
Concrete holds whatever temperature the ground feeds it. An uninsulated slab couples the house to the winter ground and works against every heater in the building for as long as the house stands, and there is no retrofit: the edge detail and the under-slab layer live inside the pour. The second half of the problem is timing. Insulation, heating coils, mesh and concrete all have to land in one window, and when four companies own four slices of it, whoever turns up late decides what the slab ends up being.
We run the window the layer goes in.
Edge insulation is detailed into the boxing rather than glued on afterwards, under-slab systems go in where the design calls for them, and where there is underfloor heating the installer is one of the trades we book and chase. Every insulated option is priced alongside the standard slab, so the comparison is real numbers rather than a guess, and the recycled option sits on the same list: Sustainable Plastic Raft, TC1 from $135.00/m². Over 25 years in construction sits behind the sequencing.
Ask for both numbers on one quote. Ring 021 222 0952 and Mark will price the warm version beside the standard slab.

The insulated foundation, in detail.
Why this crew for the concrete.
Concrete work rewards the same thing foundations do: sequencing. Insulation, coils, mesh and pour are one job with four names on it, and the crews that do it well are the ones running that job themselves rather than turning up for a slice of it.
