Slatted tank

Could it be done with Normal concrete panels did originally price the pre cast slat channels and they were about 25k

How do you deal between the panels?

 

[valtraman]

I was thinking putting h beams in like u normally would put panels in with and run the panels along the inside of posts clamped to them , not sure about strength wise with having slats sitting on top of them

But it would leak, and the steel would rust

 

[valtraman]

How would it leak though if it was all sealed up with the mastic stuff and all back filled, surely if it did leak somewhere it would seal itself up

I'm not so sure

You could seal it the same as the precast sections, put a strip of the sealing strip up the side of the panel then push the next one tight against it, same along the top of the panels, we seal over the joints with mastik as well.

Anybody care to guess the price to do it with panels and h beams concreted in?

 

[Half Pipe]

have seen single row of slat tanks done with single shutters along inside of tank and the dirt on outside, depends on soil type tho.
but that saves on shutters and backfill.
the shutters are braced from shutter at other side of tank

What is wrong with blocks?

The last line of my above post would be the main problem , 7 newton. No rebar either, plus you could make a shuttered wall 12" thick if you so wish , which wouldn't work out any dearer than the plastered blocks.

Plenty of tanks built with blocks in the 70s and still going

We have tanks built with blocks. Still going strong. Shuttering is the only method these days I would build a tank. Fast,'tidy and a strong well finished job.

Indeed there were. But most were either 5 or 6 ft deep. A builder whom I would count as not afraid to sail close to the wind told me a number of years ago , "Its a whole different ball game to go from a 7 ft tank to an 8 or 9 ft one. Huge inward pressure from outside is a bigger problem than the weight of the slurry inside. ". He did a 12 ft deep tank , built into the side of a hill 4 years ago. He did the walls 14" thick

 

[zyklon]

That's why you build peers to cope with the increased height. Still not worth it compared to shuttering.

I only ever seen one tank less than 8 ft deep

 

[P.O.T]

We asked sepa about blocks and was a no go for them had to be shuttered. Priced the horizontal panels vs shuttered wall and wasnt overly much in the price tbh. Shuttered concrete stronger and no chance of leaking.

Until approx 10 years ago , maybe 15 , all tanks over here were built using 5 x 2 shuttering pans . 1 standing up , and then a row running on the flat , so 5 ft +2 ft = 7 ft..
I wouldn't have heard of anyone building an actual slatted tank using blocks in the last 30 years , maybe a small effluent tank , and even those would be mostly shuttered. In the late 70s early 80s , some smaller jobs were done by people themselves using blocks. Not many with the time now.
Since then people most people are using the 8 ft x 9ft pans. Depending on ground conditions , i.e. Whether rock or springs are encountered , depends on which way the pan is positioned , as in an 8 ft deep or 9 ft deep tank.
If you are adamant you want to use blocks , fire away. It will cost as much , and be a far weaker job. Unless you tackle it yourself , there is no saving whatsoever to be made financially
I personally wouldn't waste my money using them. Everything here is shuttered. Even the walls under the diesel tank.

I think the fact they are only 7 newton concrete will be a problem as they could degrade in the slurry over time and by the time you have put rebar in them and filled i don't see any saving,we have the right sort of clay here to dig tank walls out and fill with concrete then dig the middle out and concrete the base i will think of doing this on a shed for myself if the structural calcs stack up with having no starter bars in the slab, on the plus side the ground around the edge will not be disturbed so should be better load bearing than backfill

 

[yin ewe]

Have seen a few tanks done by digging a trench around the required shape and size, then fill the trench with concrete and dig out the inside. finally concrete the floor. The ones I saw had the tops levelled up with 2 or 3 rows of block before putting on the slats. depends on the type of ground you're on I suppose.

Alternatively Moore Concrete in Northern Ireland make a concrete H post to use with 6 inch panels for underground tanks.

where in the country are you based
you could shutter it for about 15000 depending on the price of concrete where you are
