FAQs

Question 1

How much does a foundation cost in Manawatu / Whanganui?

Accepted Answer

For a standard 150 m² house on good ground, allow roughly NZ$25,000–35,000 for a raft slab, excluding GST. Sites needing screw piles or ground improvement can reach NZ$60,000+. Always obtain a fixed-price quote after soil testing.

Question 2

Do I need a geotechnical report before talking to a foundation specialist?

Accepted Answer

Yes. A recent geotech report provides soil bearing capacity, liquefaction risk and groundwater data—essential for accurate design and pricing. Most specialists will arrange testing if you haven’t done so.

Question 3

Can foundation work continue during winter in the region?

Accepted Answer

Concrete can be poured year-round, but extra measures—heaters, admixtures, weather breaks—are needed when temperatures dip below 10 °C or winds exceed safe limits. Schedule flexibility into your programme.

Question 4

What seismic standards must my foundation meet?

Accepted Answer

Designs must comply with NZS 3604 or site-specific engineering to meet NZ Building Code B1. In medium to high seismic zones, additional reinforcing, hold-down anchors and pile depth may be required.

Question 5

How early should I book a foundation specialist?

Accepted Answer

Quality teams are often booked 2–3 months in advance. Engage a specialist once concept plans and geotech data are ready to secure your preferred start date and fast-track consent documentation.
