Earthworks in Blenheim & Marlborough

DirtPro is an owner-operated earthworks contractor based in Fairhall, Blenheim, working across the Wairau, Rapaura, Renwick, Seddon and Picton. We handle the full range of earthworks — from a single residential pad through to bulk hilltop cut and fill, vineyard preparation, drainage, and site remediation — using our 14-tonne Hitachi ZX135 excavator, Hitachi ZX55 mini excavator, and Isuzu CXZ 390 tipper truck.

What "earthworks" means in Marlborough

Earthworks covers any reshaping of the land — cutting, filling, levelling, trenching, and the cartage that goes with it. In Marlborough that usually breaks down into a few common job types:

• Cut and fill platforms for new builds, especially on the hillside sections around Brancott and Fairhall where flat ground has to be carved out of slope. See our 3,000m³ Morven Lane project.
• Drainage and swale work — installing new drainage on steep sites, or clearing existing vineyard swales before they back up and erode. See our Dry Hills Estate swale maintenance.
• Vineyard preparation — post removal, ripping, levelling, and access track work for redevelopment.
• Site remediation — fixing slumped or rutted ground, replacing contaminated topsoil, reshaping for new use.
• Demolition and clearance — pulling down old sheds, retaining walls or slabs and carting away.

Working with Marlborough's ground

The Wairau plain is mostly free-draining river gravels — easy to dig and easy to compact, which makes for straightforward platform work near town. Move up the hillsides and you start hitting heavier clay-based soils that hold water longer and need more careful drainage planning, especially after a wet spell. On steep sites we contour platforms to shed water naturally where we can — it's cheaper than installing formal drainage and works with the land instead of against it.

Vineyard sites bring their own quirks: you're often working in narrow rows with established vines either side, sometimes on land that's been reshaped two or three times over its life. Knowing what's underneath before you cut saves a lot of grief.

Resource consent — when do you need it?

Marlborough District Council's Resource Management Plan sets thresholds for earthworks based on volume, slope, and proximity to waterways. Small residential pads on flat ground are usually a permitted activity. Larger cuts — particularly on slopes greater than 25°, near streams, or with significant volumes — can trigger a resource consent. We're not planners, but we've worked enough sites to flag likely consent issues during the quote so you know whether to factor in MDC time and fees.

If you're unsure, MDC's planning team can give a definitive answer for your site before you commit.

Why owner-operated matters

Every job DirtPro takes on is run by John — quote, walkover, machine work, and tidy-up. That means you're talking to the person who'll actually be on your site, not a sales rep handing the job off to a sub-contractor. It also means decisions get made quickly when something on-site changes — a wetter-than-expected pocket, a hidden tree root, an access change — without phone calls back to head office.

How to get a quote

Most jobs need a 10-15 minute walkover before we can give you a number. Call 021 0226 1219 or send a message with a rough description and a few photos and we'll get back to you, usually the same day.

Common questions

How much does earthworks cost in Blenheim?

Earthworks pricing in Blenheim depends on the volume of material to move, site access, and how much can be reused on-site versus carted away. As a rough guide, simple residential pad work runs from a few hundred dollars per hour for digger and operator, while bulk hilltop cut and fill jobs are usually quoted by total volume after a site walkover.

Do I need a resource consent for earthworks in Marlborough?

It depends on the volume, the slope, and how close you are to waterways. Small flat-ground pads are usually permitted; bigger cuts on steep sites or near streams often need consent. MDC has the final word.

What size digger do I need?

Residential pads, trenches, drainage and small site work — usually a 5-tonne mini excavator. Bulk earthmoving, hilltop cut and fill, or rural land clearing — usually a 14-tonne machine. We run both and bring whichever suits the site.

When is the best time of year for earthworks?

October through April. Drier ground, longer days, fewer weather delays. Winter work is fine on flat sites but steep work can be slowed or stopped by rain.
