About Concrete Contractors Hamilton

Concrete Contractors Hamilton builds driveways, house slabs, patios, paths, commercial hardstand and rural pads across Hamilton City and the wider Waikato. Licensed, insured, and ten years into the trade here.

What we are known for is looking at the ground before we price the job. Roughly a quarter of Hamilton sits on peat, and free-draining Horotiu soil sits within a street of slow Te Kowhai gley. None of that reads off a map at property level.

So every job starts with a free on-site assessment, and the written quote that follows is based on what your site actually needs.

Who You Are Dealing With

Hamilton Owned, Hamilton Based

We work from 20 Alma Street in Hamilton Central and pour across Hamilton City and the wider Waikato, from Rototuna and Flagstaff through to Tamahere, Horotiu and Ōhaupō.

The crew is licensed and carries public liability insurance on every residential and commercial job. Ten years in, most of our work now comes from people who have seen a driveway we poured for someone they know.

If the honest answer on your job is repair instead of replacement, that is what we will tell you at the visit. It is a smaller job and we would rather have it than sell you a slab you did not need. More on the full range is on our concreting services across Hamilton.

What We Build

Concrete Work Across Hamilton City

Three kinds of customer call us, and the ground under each of them behaves differently. The work is the same trade. The build is not.

Residential

Driveways, house slabs, patios, paths, steps and shed pads. A standard driveway goes down at 100 mm in 20 MPa over compacted basecourse, with 665 mesh in the top third at 30 mm cover and joints cut.

That build carries cars, utes and vans up to 2.5 tonnes.

Commercial

Warehouse floors, yard hardstand, car parks and loading areas, staged so a business keeps trading. Thickness starts at 150 mm and the grade follows the loading, 25 MPa to 3 tonnes gross, 30 MPa above it, 40 MPa where solid tyres run.

Surface tolerance is set in the specification before the pour.

Rural

Implement bays, shed floors, dairy hardstand, tanker tracks and lifestyle block driveways around the Hamilton fringe. Heavier point loading and worse ground than city work, so joints and steel get designed for movement.

Peat in the Rukuhia swamp has been measured subsiding 25.6 mm a year.

How We Build It

The Standards Every Job Is Built To

Most concreting quotes describe the finish. Ours describes what is under it, because that is what decides whether a slab is still flat in ten years.

Curing is a minimum of 3 days, and 7 where heavier traffic is going on it. Foot traffic once it has had a day or two, vehicles at seven days and longer in winter. We give you the timeframe for your pour rather than a rule of thumb.

Why We Look First

Hamilton Ground Decides the Job

Two things about Hamilton ground change what your job costs. Which soil you are on, and how deep the water sits.

On the free-draining Horotiu soils across the low mounds a standard build works, around 100 mm of compacted basecourse under the slab. Drop into a Te Kowhai swale and that goes to 200 mm or more with subsoil drainage, and the job costs more.

Peat is the other one. It covers 19.5% of Hamilton City by area and Council geotechnical work puts peat soils nearer 24%, almost all of it on the western side. There we design joints and reinforcement for ground that keeps moving, and where the peat runs deep the slab needs an engineer.

You cannot tell which you have from the street, and neither can we. That is what the free site visit is for.

Paperwork We Handle

The Council Side of a Hamilton Concrete Job

Where a job touches the road reserve, the approvals sit with us. You are not chasing Council between quotes.

Vehicle crossing applicationLodged by us, residential 3 to 5.5 m wide at the boundary
Commercial crossings5 to 7.5 m, built to RITS 3.3.19
Corridor Access RequestRaised before work starts
InspectionsPre-pour and final, booked with 48 hours notice
Public liability insuranceEvidence supplied with every crossing application

Hamilton City Council states it needs to approve, inspect and sign off new crossings and repairs, and to be contacted before work starts. Repairs are included in that, which catches a lot of people out.

Free on-site assessmentThe assessment is free. We look at the ground, the falls and the drainage first, then put the quote in writing.
