Is your drainage project being impacted by plastic supply issues? Talk to us about using concrete

Plastic manufacturing is facing global supply pressures which is impacting pricing and availability across the civil sector.

Concrete pipes are a great viable alternative in a range of sizes if your is being affected by plastic drainage product costs or availability. Talk to us, and we can offer alternative options.

“Pricing for plastic pipe may be one of the key challenges for Councils, engineers, and contractors at the moment, but availability is also a concern,” says Jim Marshall, Regional Manager for the Lower North Island at Humes. “We hold concrete pipes in stock in most sizes across the country, and if we don’t have what you need, we can often manufacture it. Get in touch with us - we’re here to help you transition from plastic to concrete where it makes sense.”

Key Considerations for using Concrete Pipes:

Suitable applications:	Concrete pipes are ideal for all types of stormwater projects.
Where they can replace plastic:	A practical alternative across most stormwater construction, particularly in standard sizes (e.g. 225 - 450 mm and above).
Applicable diameters:	Concrete pipes can replace plastic options from 225 mm diameter upwards.

Why Choose Concrete Pipes:

Built for strength:	Handles high loads and demanding site conditions.
Easier on-site:	Reduced reliance on specialised bedding materials.
Long-lasting:	Designed to perform for 100+ years.
Better long-term value:	Lower lifecycle costs compared to many alternatives.
Lower environmental impact over time:	Durable and recycable.
Support when you need it:	Technical advice, service and installation guidance available.
