No joints crossed but looks interesting.

Interesting product.
Are the joints level because of the steps along the slope?? I would of thought half units would be available, they dont look like fun to cut on site..
Is the big hole for a dowel?

If I remember correctly you could do up to a metre without a design as such.
Laid on a fabric reinforced strip footing, think it was 150 or 300mm deep. Had to chip the tongue off your first course and bed with mortar then dry after that and you just had mortar on top course for coping.
External corners where special cut and stick blocks, internal corners never had one to do on that job

My turn to have a play at this. I want to build a 2m - 2.5m high wall at the back of the yard. Shouldn't be retaining anything as mostly rock anyway, but want a nice clean wall to tidy things up and tip against. Planning to use steel columns every 8.5ft with concrete railway sleepers horizontally between. Cheapest easiest way I can think off and will be free draining and not require footings, so my French drain around the bottom can stay in place.
Not sure what steels to go for. 10mm thick got dipped galv would be nice. Need to be about 3m to 3.5m long as will be concreted into holes. These blue steels are up for sale locally ( I have met the seller) and would keep cost down, but I think 5mm too think, and only 50mm web to catch the end of the sleepers is too little. Dont know a lot about steel calcs/prices ... but I do know that 254x254 is going to make my eyes water .. Need about 5 or 6 at 3.5m long ( bury about 1/3rd in the ground)

Actual concrete panels aren’t expensive for what they are - you could have them 20 feet long and use fewer (but bigger) steels.

I want to use sleepers as I need to dig them into the battered banks at either end so will need to cut them to suit. Works out a lot cheaper on the panels, but not calculated it with less steels

well yer blue ones are gonna need shot blasting and pickling, 'fore the galvanizers'll look at them and they will need to be surgically clean/devoid of paint . 254 x 102 x 23kg/m - pretty flimsy TBH
what's wrong with 203 x 203 x 46kg/m ... concrete sleepers aren't 7" thick on the ends surely ... a good strong section over the length you're talking
available in 6m, 7.5m, 8.5m, 9m, 10m, 11m, 12.2m, 14m, 15.3m 16.8m &18m .. a 7.5m and a 14m, wold give you six -990kgs @circa a grand a tonne - do it once and bitu. coat what's in the concrete and any faces in contact with anything - just leave front faces clean

Just cut the panels!
They sell seconds near me for £100 a panel (cash) - nothing really wrong with them, sometimes just been made the wrong length for a job.

don't think they'd be up to a retaining role .... more stress free walling, but if there ain't a lot behind 'em they'd make a lovely walls

Sounds sensible. I need to drill a test hole first, then I can measure it out and plan it. Sounds like about £1500 for the posts once cut and dipped, and I think about £1000 for the concrete all delivered.. will need to sell something
Sleepers are 7” so should sit in a 203mm happy enough.

galv's by the tonne, so will be all of 500 quid ... tell the stock holders you want clean, blue material as it's getting galv.ed .. not the rusty crap at the back of the yard. (and you'll send it back if it ain't up to spec. - you're paying for fresh, clean material)Sounds sensible. I need to drill a test hole first, then I can measure it out and plan it.

I know Dyfed get down your way and there's bound to be other stockholders - getting the beams halved/quartered'll not add a lot to the cost of supply and helps the transport dept.
if you were to go with Dyfed, I'll give you 'my man' in Zooport to talk to, or I'll suss a figure for you
dealing with Llanelli office is like trying to have a sensible conversation with chimps on crack

Westcountry Concrete are about 1mile from me... 15ft x 5ft x 4" panel about £300+ vat last time I checked. Sleepers are approx 30-40% of the cost of panels based on fag packet maths. Concrete panels would be smarter certainly, but sleepers better for what may be a retaining wall. Plus I cant handle anything bigger than a 15ft panel Thanks for the advice so far

I would go for one one the local steel suppliers. Surrounded by them here. Think the local dippers are Crediton.galv's by the tonne, so will be all of 500 quid ... tell the stock holders you want clean, blue material as it's getting galv.ed .. not the rusty crap at the back of the yard.

do you have a good source for the concrete sleepers - make excellent roads/hard standings too, if you prep rightWestcountry Concrete are about 1mile from me... 15ft x 5ft x 4" panel about £300+ vat last time I checked.
