Cost of digging out for a 3 bay tank

shrek008

Whats the average cost of digging out for a 3 bay tank, backfilling as well. Good ground and no rock

Count Mondego

I'd hazard a guess at 3-5k.

You never really know what it's going to cost you to get out of the ground until you're out of it.

Pitching it at 60 to 100 hours, but very difficult.
Multiply by €45 per hour.
Count is right.

Are you including the removal of the spoil and supplying stone, it seems an awful lot of time to dig a hole that size?

Four bay tank was dug here in 8,5 hrs and stockpiled. Another 8 backfilling and levelling the spoil into a slope in the field.. I think the whole lot cost a sum total of around 700 plus vat. But if you'll pay 4-5k il dig it with a shovel for you.

I'll do it with a teaspoon

700/day for a 20t with a driver sounds about right (or maybe that's the price with a rock breaker also?). Do you have somewhere to stockpile it, if the stockpile is only temporary I'd make the effort to find a more permanent home now, and be done with it, where this be with a bank around the yard, or filling in a hole down the field. I'll have to get a hole dug out for a 105ft x 16ft tank, and the soil drawn down to fill in afew holes the edge of feilds, and I'm factoring in about 3k for the dig and 2 tractor/dumpers, that's assuming we don't hit any rock etc!

Actually that's a reasonable question, are trial holes any use beforehand? Say 3 of them across where the tank will be, each 10ft deep to give me some idea what's underneath? And who would ya get to drill them, how much?

I had a five bay tank to dig out. There was rock there that came up, rather than rock broken out. The digging took 3 days. Backfilling was another two days. The spoil was brought to the end of the field and put down in a swamp area that was dug out first, this part involved 2 diggers and two dumpers. Including the Stone for the floor of the tank it was 6k. Spoons would be a while at it.

Is there any point in digging trial holes. If the shed has to go there it has to go there. If it is a grant job you need planning permission. IMO you should be getting PP anyway. Not sure about a 20 ton machine breaking rock. The stone you end up with is in big lumps and little use as fill. Dug out two tanks over the last 10 years. One thing about smaller machines is the stone is much more useable if you have a use for it. What is stone costing now up on 200/ load Rx vat it is so long since I bought stone I am unsure and I still have a few hundred ton around the yard

OP when digging out keep any top soil to one side always hand to have a bit. If no rock no need of a 20 ton machine any lad with a 10-14 ton machine is adequate. About 35-40/ hour + vat. Vat is reclaimation. If you can get a dumped for your tractor and another lad with you it should?D be dug out in a 10 hour day. If you are sloping the side of the openings I keep some of the spoil as fill for outside the stone as you backfill. You are bound to have a bit of low ground that can be filled with the rest

Forget the rock breakers lads, he said no rock in the first post. He's bound to have an area close that's in need or can hold the fill and still make a right job of it.

Usually costs about 8 euro per m3 of excavation

I kept my head down since I suggested a figure much higher than later posters.
C€700 + vat.
Well on your figure, Boaty.
18 metres long, 6 metres wide and 4 metres deep = 432 M3
432 by 8 = €3,456

Also if its all soil, you have to buy in back fill stone and digger for that.

Would hate to see the OP thinking it might be a very low figure. Hope I'm too pessimistic on the other side.

Mooooo

Any tank here involved rock breaking and drains around them, hope to put in a tank on another yard afraid it'll be the same thing

It's just what it cost me, 4 bays mixing point at both ends, backfilling with stone would be done in two hours max, it's even faster than with clay. Any machine driver worth his salt will have it out in a day no issues.
