Max wall length without piers?

eamon11

Hello Folks,

my neighbour who wants to build a single leaf 4 inch block shed asked me the other day what's the Max length he can he can build the long wall without having to put in piers. I couldn't answer as I don't know. The walls will be to eve height only as he is doing a flat roof.

thanks a lot

Block on edge load bearing wall? I think the answer is "nope".

as in building a 4" block on edge wall as a single lea and then roofing ff of it is both stupid and dangerous. 6" or 9" cavity block minium. block on flat is a great way to build a strong wall.

thanks for reply,

you are saying that even with piers he cannot use 4 inch block?

well water , thank you for telling me what I asked as I had totally forgotten. You really seem to be doing your homework! Full marks to you. And thank you so much for your helpful contribution, you have really cleared things up for me.

well said eamon, this forum used to be a nice honest down to earth place to come just a few short ago where people looked for and gave advice. Now it's full of know it all smart alicks who will insult you for the questions you ask while investigating your life history!! Less of the negativity and "stupid" and "dangerous" talk too. The op is simply asking a question, y'all need to chill a bit.

I never check anyone's posting history. OP asked a Q yesterday and I answered without an issue. Just wondering why a parallel Q had arisen. No need to take offence.

its not negitive if its true.

have you ever seen a shed fall down when built that way . i have. a small garage barely the size of a car and room to get out. a guy reversed a trailer and jeep into the side of it and the whole wall caved in and brought the roof down on a almost new car.

it is a stupid and dangerous way to build anythng

we are all here to help. i help at every opertunity

Pen..blah blah..you are an alarmist... nothing more. Did the op build this? Did his neighbour? Why you feel the need to incorporate these words into your reply shows your prejudice. And still you don't mention what the op has asked. Specifically about the use of piers. You are so quick to reply now that is argumentative but you didn't bother to reply to his follow up question to you "thanks for reply,
you are saying that even with piers he cannot use 4 inch block? "

Water,
One question had nothing got to do with the other. Even if it had why not reply if you know the answer. Or, don't reply if you don't. Why you feel the need to inform...with such a helpful link… all and sundry that the op asked a question somewhere else on a different day is beyond me. Oh and dont forget the oddball comment. So you weren't wondering anything….your digging now..
Thread has degenerated into a farce like so many others on here. You will not get an answer OP. Just negativity and “oddball” comments.

Mod, please close this thread.

not sure what im predudiced against.
if you read my first post in this thread it gives 3 options for the OP to use that would be a lot better than 4" even with piers.
i wouldnt build it with piers but if i had to use 4 " on edge i would add piers but that would be a last resort.

sorry about not repling i was watching the jungle.
you can use piers with 4" on edge and it will add a lot of strength but it would still not be the best way to build it ,

im not a structural engineer or similar so cant say how close the piers need to be . that would depend on size, and span of the shed

I'm not closing this thread. Users can either answer the question, ask for more information to help to answer the question or ignore the thread.

It's simple stuff, it's a help forum.

I don't know the answer.

So if someone does please share it let that be your motivation to post here.
Thanks.

To expand slightly on my nope, I looked quite extensively for any source of information on building an external load bearing masonry wall of 100mm thickness, and found nothing. This is because it is a bad idea.

The material savings over block on flat are inconsequential, and you don't save any useful space over a thinner wall with piers.

Ok all.

If the next post here is not an attempt to answer the op question, action will be taken.

Don't sandwich in some pop shots either please.

100 mm block walls should not be built higher than 600 mm without support. Size, spacing of supports will have to determined by a structural engineer who will charge a hefty fee for the design

Ok, everybody chill. I would not build a single on its side block wall with a load on it. Far too weak. I would ...do it with thick pillars , if the loads are directly on the block pillars. At a guess small light flat roof with 8 ft high wall...I'd put pillars not more than 10 ft apart and slightly higher than wall and of course pillars on corners. What do the builders here think?

Op: without knowing the site conditions, wall height and appropriate wind load, you can't determine what will work.

Having said that,
if

1. foundations are 3 times width of block,
2. are at correct depth for frost heave
3. good ground,
4. not too exposed to wind load on wall/roof
5. 4" solids on flat are used

piers would be needed every 4 to 6 meters.
Piers need the foundation widened to suit.

I have a 4in block on edge garage with a pitched roof that was built in 1975 or there abouts. Its probably about 4m x 5m. It is in a windy location and there are no cracks or any other visable defects. Maybe im just lucky?

I'd say it's more about the quality of work than luck studdly.

There's an awful lot of sheds built that size and even bigger around the country that are withstanding the worst of weather. A very good foundation and a very good block layer is half the battle.

Someone from work told me that their house is built from a single skin of solid blocks (non-timber frame, 1980's build) which I found very hard to believe. But they were quite sure as they'd only got new windows recently and the window fitters couldn't even get over it, apparently, the estate is like that. I've seen some dodgy kitchen extensions built like that but never a whole house.
