Silage Clamp

How much hardcore do you have under the 100mm of concrete @Fraserb ? And how far do you extend it past the edge of the panel?
The amount of hardcore depends how good Ive been with the digger,;) Usually we make the whole site up to just below the required level then dig out the trench for the panel base, aim for around 300mm past the panel each side

One of them would be good ! if i was building mine again id chose asphalt over concrete as well.

I'd always be bothered about someone sticking the pallet tynes or similar under the asphalt,the front of my clamp gets a hell of a battering from arctics and such,not sure asphalt could hack it.

Quite a few asphalt pits up here they seem to fair ok most look better than concrete after a few years but i know what your saying.

These are what we are using for an underground tank. I am naturally cautious, particularly as the EA are interested, but like this design. I will sit them on 150 thick concrete,with a 20mm fall to the centre, so we can pack the feet up so they all look neat and straight. From JP Concrete.

Our existing clamps (35yrs old) were asphalted 10 years ago when the concrete needed replacing. Quite like the finish it leaves but you only have to get the shear grab at the wrong angle to rip some deep lines in it

Look at a bock clamp, sorr of panels on a soil bank.

Is this a design your using? Do you think there would be any issues getting silage off the sides if it can't be cut with the shear grab? One of our clamps, an earth banked clamp, has to have the sides shovelled off to leave a clean finish. Typically always left too long and silage spoilage

I've a clamp the same design,no problem with getting silage off the side as it's very steep.

I also have a soil bank and that's fine when your moving back fast,the mini digger is best for pulling silage off without moving the side sheet.

Presume you lay a thin layer to get the level right? The panel companies were all recommending a 150mm deep plinth of meshed concrete under the panels and then concreting over the foot too
That will be the overturning forces from the L shaped into the footing don't skimp on this,Myself i would put steel columns in every 20 ft extended above the wall top by 1.2m to take your sight rails and have a plate on the top of them to roof over if you ever need to if you use panels the foundations for the steels are massive ,also you will need 180mm panels ,150mm will do it but if you put a concrete kerb around the outside the bottom panel is fixed and the ones above can deflect slightly and break the tongue of the edge of the panel under load Perhaps @Unbrako precast can help

How does the stone levelling device work,do you have to do it in a few directions ?

It was actually built for doing roads but thought I'd give it a go on the pits, scraped a buckets width round the outside to correct level then they roughly dumped the rest in slowly reversed over it using the scraped bit to stay right, once I'd done that just scraped over any high bits and it worked out spot on, the length of it means it almost keeps its self level.

That was the first time I'd used it for anything other than roads and i've used it a few times since when on big areas.

If the bottom panel is restrained the ones above can flex and break the tongue etc , mostly however you get away without that happening, the ideal is to cast in the bottom panel and ask for the bottom row to be flat topped ( no tongue ) , this gets the best of both worlds as it stops effluent leakage at the bottom and prevents damage.
On another matter .
Have people had big problems with concrete floors in silage pits why tarmac is now sometimes suggested ?

Silage effluent corrodes comcrete, no matter how strong. If you coat it wth something that soon wears off, so the answer is to coat the stone with tar, ie tarmac. It resists attack by the acid in silage effluent, but as it is not as compacted as concrete, is more easily damaged by careless use of machinery.

can you still have the beveled edge for the mastic joint on the flat edge panel ,it sounds a good idea
