Silage Clamp

[SJM]

Currently have a planning application in for a 40x15x3.5m silage clamp and am considering shuttering the walls. Based in the Midlands

What thickness of wall would people recommend? Would we need to put steels in it? Would prefer not to because of the silage effluent. There would be 332.5 m2 of wall which, if we went 300mm thick, would be 100 cube of concrete.

Anyone be able to give an estimate of what it might cost?

Will also be laying 780m2 of floor including an apron in front of the clamp.

Thanks

3.5m high?
Roofless or do you plan on buckraking with a 135?

 

[SJM]

No roof... sky's the limit!

Panels would be easier. And probably cheaper, but probably not as good, ?

Priced up vertical cantilevers and L shaped ones. Both types need a huge amount of concrete to install them (apparently) so was wondering how comparative shuttering is

Recent quote for 6 inch concrete with mesh and layed was £32 a square metre.

I think shuttering will always work out as an expensive option

Just to supply the concrete, mesh and lay it?

We use the L shaped panels and they don't need huge amounts of concrete to install.

Yeah concrete mesh and lay. Along with effluent channel outside of walls.

Looking at another quote was £26 square metre for concrete mesh lay.

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

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

L shape panels are working out at roughly £70/sqM just for the panels without any concrete under or over them. Is there anywhere I could find a rough estimate of cost/sqM for shuttering?

I'll work you one out

We lay 100mm of concrete without mesh under them to get level correct, set the panels in place, tie them together with rebar and concrete up to the foot not over it, that's the way we were told to do it and done a few now no problems.

 

[RWG Contracts]

What you've got to remember is the firms that supply the panels will spec it so as to cover there ass for in case anything goes wrong

Thanks, much appreciated

Thanks for that. Are these L panels with a full precast foot or panels with rebars sticking out of the foot to tie into the floor mesh? Been quoted both and quite a price difference!

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?

Ours have a foot of concrete sticking out approx 500mm then 1m of rebar sticking out of that.

Not the best of pics but you can almost see them in the pics
