Aaz Posted November 10, 2015 Report Share Posted November 10, 2015 I'll be surprised if the hole stays open if left over night in this weather, I hope you're not in 2.2mtr hole with a spade straightening up the sides!! thats what the machines for. ballast the tank with water and a nice lean curb mix, anything wet will just lift the tank as you fill around around i, lay yourself a nice level base - using the machine and put the tank on it then, start the water and back filling. Don't overtake the water with the concrete. Have fun! Quote Link to comment Share on other sites More sharing options...
Aaz Posted November 10, 2015 Report Share Posted November 10, 2015 Well I bit the bullet and hired a digger spent 6 hours digging today , first foot was full off roots and I mean roots then two foot of soil one foot of clay and the rest all sand , good news for the soak away Got the ladders out and went down thought Australia was in reach , had a play about with the spade straightening the sides and lowered the tank in to see if it fits left it in over night , concrete tomoz and settle the tank in , soak away to dig trenches to dig Recon about twelve tonne of soil, sand on my drive if any one wants any lol Cheers guys for advice Sand isn't the best for a soak way, it clogs up very easily and as you're putting in a septic tank will clog up even quicker and you'll be doing a new soak way quicker than you anticipated! If not too late I wouldn't leave the hole open, chuck in what you've dug out, it'll take 20mins to dig out again but will hold the sides up so it doesn't all collapse.

figgy Posted November 10, 2015 Report Share Posted November 10, 2015 Be careful going inside excavations as plenty of folk have been buried alive when the sides cave in. Quote Link to comment Share on other sites More sharing options...

polester Posted November 12, 2015 Report Share Posted November 12, 2015 Think I'm having a blonde moment , why fill it in with wot I've tuck out It's to hold the sides up if you've already dug the hole until you are ready for the tank. Usually you dig the hole in the morning, get it passed off by building control mid morning (if you have to) and pour concrete as soon as you can. The longer you leave the hole open the more likely it is to cave in especially with any rain. **** law a side collapses just after you have leveled the concrete base and tank is lowered in pushing the tank out of position. Just get plenty of water inside the tank as you fill up with concrete. It stops the tank moving and possibly imploding with the pressure from the concrete.
