How big for vertical joints in blockwork?

    Hi all,

    I have an old brick cow shed that has a concrete floor which is unlevel so that all the cow expulsions could drain out, we are splitting it into two using a stud wall lined with OSB, I'm leveling the floor first with blocks to provide a flat run for the base plate of the studs to go on, for over half the floor I can use a single course of concrete blocks just cut in a taper to get it nice a flat, but the issues come in the last bit where it gets to it's lowest, I will need a full course of blocks with then another course with a 3rd of a block (also in a in a taper), I know that vertical joints are the worst and can cause structural issues, but it will make the cuts a lot harder if I don't just stack the 3rd of a block onto the full block. And I have to get it level. Nothing more than some garden hand tools and a shelf for other gardening goods will ever be hung off the wall.

    Now you have my life story, the simple question is for a run of 4 blocks, will I get away with vertical joints rather than staggering them given the other course will be at maximum a third of a block?

    Hope that all made sense,
    Cheers

    Had a similar problem, what we did was get a 100x60 lintel of the right length installed that on the floor at one end and packed up level at the other. Fill the void with, concrete and then build on top. Lintels are not cheap but that way can save a lot of time and hassle.

    Interesting, didn't think of lintels... That would solve my concern of the vertical joints, but the more I think about that the more I think I'm worrying about nothing as it's not that much bigger the joint.

    Did you get the lintels for a standard DIY store?

    You need a builders merchant rather than a shed!

    We have a local lintel specialist - and there are plenty around.

    A limited range though ... Our local lintel specialist has a yard as big as the local B&Q. And will trim to size if required.
