I'm looking to rebuild my garage/driveway as the original 1960s builders took the easy way out and built up rather than worked with the land. I have established (until I remove the garage properly) that I have around 30m3 of soil to remove and dispose off. This could be a combination of greywacke and normal soil but unknown till the surfaces come up. I know you can hire the 3m3 bins for this, but that would be approximately $3K for this activity and I wondered whether there was a cheaper option for bulk disposal. My NZ google fu has so far failed me and I cannot find bulk removals of soil... Are there such facilities in NZ?

Thanks,

Chris

Are there any large projects around you that involve reshaping the land? There is a small industrial area a few km from me that is going on top of that was a bit of a culvert that has been filled in.

building on that I've just found http://www.look4fill.co.nz which appears to be a notice board for import/export! I'll have a look and see how that goes...

Try and google landfill sites. They should accept this reasonably cheaply.

Then you need bulk transport. Truck & Trailer units can take about 22 cubes per load. So truck & trailer unit, plus 1 truck might do.

Finally you'll need a digger. Should still save you a lot of money from $3k.

Swimming pool builder contractors do this all the time so you may like to look into that. They often use a man with a bobcat and a couple of trucks and the truck guys know who/where fill is needed - either a landfill or a development project of some sort.

Sometimes I just sit and think. Other times I just sit.

I think you need a consent to move that much soil also...

I disposed of about 20 m2 hardfill when I did EQ repairs at out place. IIRC, I hired 5m2 skips (Envirowaste). Hardfill dumping in Chch was free - if you could get it to Lyttelton, but it still costs money to cart and dump. Total cost was less than your $100/m3 - remember that each m2 will weigh 2 tonnes or so, so $50/tonne, which was about what Council charges for dumping alone (plus you still have to cart it).

Bugger loading 30M2 of soil by hand. First step, get an earthmoving contractor to give an estimate to do the lot, then decide whether the amount of sweat involved is worth it. Wasn't possible in my case, as there was no possible digger access, so it was going to have to be carted in barrows. Skips were the only way to go. OTOH if you can get a contractor with a digger and dumptruck in, you'll save yourself untold sweat and grief - and it might be cheaper or not that much more expensive.

The $3k that you've worked out sounds like it's in the ballpark.

Where are you located?

Auckland/Waikato allow residential movement upto 50cubic meters without resource consent, rural plots get 250m3, and I'm still 40m3 under that and have a large shallow depression in looking to fill with clean soil (stone not an issue but rubble is!)

I'm just west of Pokeno, but missed out when they were clearing that development a couple years back, how far are you from here? 🤔

I'm west Auckland, so about 53kms from Pokeno. I'm just working out how to tackle the grade issue with disposing of the concrete/spoil. The concrete is easy, 2 x 3m3 skips will deal with that and 1 x 9m3 bin for the current garage/car port... The issue was the existing clay/soil that will exist below the thin concrete slab.

I'm not ready to take the garage down yet as I still need firm prices from the various companies. Once agreed, I'll look at starting the demo using a hired mini digger as I'm not intending to level the ground using a spade! Without knowing the ground profile below the concrete, I've taken a conservative triangular approach to the volumes, 750mm max depth is 0.375m x the area of the existing garage plus some driveway scrapes to grade down. I suspect it will be at least 20m3 when I'm done.

If you where able to wait and where interested, then I'm sure we could come to some sort of mutual arrangement although I'm not sure how to get it to Pokeno in the smallest number of loads to make it economical.

Last year I had a fair bit of spoil to remove from my project, probably 30-40M3. Im in AKL too. I have my only little 3T tip truck so thought I would try DIY first...

The first load I took to the tip cost something like $500 ($120/Ton from memory). So I figured with about 20 more similar loads ahead of me I wasn't going to get rich quick doing that. I shopped around a fair bit and the going rate from contractors seemed to be about $400 per "6 wheeler load" which I believe is about 9M3. That will vary depending on how far you are from the tip site, I was only 10-15min away. The only cost effective tip sites I heard mentioned were Onehunga or Silverdale, some of the bigger contractors however have private sites they can use. That is just for the truck and tipping fee, so you will still need at least a 3T digger on site to load the truck.
