What sort of building is that? Looks like a chicken shed.

Looks like 3" line. We have to push limestone crushed to 1" and under.  Wish mix would go thru 3".  What mix are you gettin?

Yes digger its a chicken shed. we are doing a hole stack of them at the moment. THEY STINK!!!!

We use 20mm/25mpa mix and they are 3" lines. A bit easier on ya back,

If I ask for a 20mm I'd have em scratchin their head.  They send me pea gravel or grout.  Thanks pmpnbear
