...the ones you build with. I have couple of IBC water carriers that I want to mount on a platform, and I wanted to build said platform out of concrete blocks (got my Bricky kit delivered). The base would be three maybe four blocks high. I've noticed they come in different densities and what I presume is a load rating. I imagine a full IBC would way around 1 metric tonne ish.....should I go for the densest block, or are the 'medium 7.3N' ones more than adequate? Me....no knowledge of brick laying....and elevated 1 ton containers.....what could possibly go wrong?!
Just build it on four inch concrete solids lay on their side you're not building bridge piers for the M4
if I want it maybe 3 feet in air - I'd need a lot of blocks to do that? Location is a good 60 yards from the driveway and up a hill so trying to avoid lugging too much stuff.
I think I worked that bit out all on my own. Its the type of block I am asking about - do I need 'medium' or should I go for the denser ones? It's nearly 25p a block difference.....things are tight.
Newtons? As is Olivia Newton John? Don’t you think 73 is overkill? I mean, I like the Anglo-Antipodean warbler as much as the next man, but 1 or 2 would suffice surely?
You used to be able to get concrete foundation blocks which were twice as thick as a standard breeze block and a lot more dense....why am I thinking "Late Bay members " as I type this ?!?
Might want to consider these if your going for piers rather than rectangles ... Handy holes make carrying the equivalent of two standard ones up a hill much easier as well! Then if you want belt and braces you can fill the vertical cavities with your own concrete mix (and anti-rust-painted metal bars if you want it to still be there in 2120) https://www.awbsltd.com/hollow-bloc...FUh-Ik-BC9_movmRRs7nNmb-VIqxLNooaApBPEALw_wcB
..... and the state of the ground you're putting it all on is probably more important, which is why piers might prove to be the "stilettos" to the "rigger's boot" of a rectangle
Those were known as yellow bands because they did indeed have a yellow band lightly painted on them and yes they will be more than adequate. Red bands were a lot denser for underground and that was how you’d spot them from a distance. You could even use thermolite as they’re loads lighter to carry but a tad more expensive.,strength wise, these would also be more than strong enough. If in doubt, pop a spreader on the top in 3”x2” timber or similar. Old pallet Wood is nice and knotty and ideal for this application And as mentioned above, it’s all about nice flat level footings Ozziedog,,,,,,,, cheap cheap cheap tooo
