Concrete grain panels

[nickf]

A friend of mine was at Lamma and mentioned that he saw a manufacturer of prestressed concrete grain panels, whereby they had a system such that you could sit a 150mm panel on top of a 200mm panel but he has forgotten who it was.

I like to use a panel below ground level to act as shuttering for rammed stone and then the concrete floor and as I am building up approx 1m at one of a new shed I want this panel to be 200mm thick. However the grain supporting panels need only be 150mm from finished floor level upwards, so if this system exists I might be able to save a bit of money rather than go 200mm all the way.

I have had a quick google search but not found anything yet.

Does anyone know which manufacturer it might be.

Many thanks
Nick

Hi have done this pin cattle sheds 150 to 100 and just cut the tongue off with Stihl saw.

But I have seen a company where they had a tongue and a groove on wider panels

Most suppliers will do it if you ask. They just add a temporary form and cast the panel with no tongue, they charge extra per panel to do this.

Thank you, it was Unbrako that was seen at Lamma, their 200mm panel has a chamfered edge so grain will not sit on it.
