Question 1

What is Permacore?

Accepted Answer

Permacore is a purpose-designed permeable concrete mix featuring an open-graded, no-fines structure. This composition enables water to pass through the slab efficiently, supporting sustainable drainage on site.

Question 2

How does Permacore help with storm‑water management?

Accepted Answer

By allowing rainfall to infiltrate the ground, permeable concrete limits surface ponding, reduces peak‑flow volumes entering council infrastructure, and assists with groundwater recharge. This can defer the need for costly detention tanks or enlarged pipes.

Question 3

Where can Permacore be used in New Zealand?

Accepted Answer

Typical applications include footpaths, retaining walls, cycleways, car‑park stalls, driveways, patio areas, and tree surrounds.

Question 4

What maintenance does Permacore require?

Accepted Answer

Routine sweeping and occasional low‑pressure water blasting keep voids clear of silt and organic debris. For high‑traffic zones, annual vacuum‑suction cleaning is recommended.

Question 5

How durable is Permacore compared to standard concrete?

Accepted Answer

When correctly designed and maintained, Permacore offers comparable service life in low‑speed environments. Its compressive strength (10-15 MPa) suits light‑vehicle, pedestrian and landscaping loads.

Question 6

Is Permacore compliant with local council requirements?

Accepted Answer

DesignHub provides concrete mix designs that meet regional water-quality objectives and comply with relevant NZS 3104 performance criteria. Test certificates and design documentation can be supplied to support building-consent submissions.
