Trench fill too high - help with making it up/down

    As mentioned in my other thread, my pumped trench fill didn't go amazingly to plan and despite painstakingly placing rebar markers AND even deliberately putting those 15mm below where I wanted they still managed to overfill.

    End result - the concrete is now about 25mm above where I wanted to start laying bricks. It was already a fairly high trench fill, so I've only got 3 bricks underground (well, I did!)

    The other challenge is that the second course up includes two lintels for drainage.

    So - what are my options here? My initial thinking is to cut some bricks down by 35mm (or blocks, whatever), to lay them on a bed of 10mm and then be back on gauge for my 'second' course

    Would appreciate any thoughts from those far more experienced in these matters!

    Can you lose the 25mm on the first 3 courses by going *very* thin on the beds of all 3? If they’re actually underground and not visible? Are there another 3 courses above them up to dpc?

    Bummer- think (unless you're a skilled bricklayer) best bet will be cutting down bricks or blocks. From a cost point of view you might be best off cutting a load of bricks in half (horizontally) and using slightly thicker beds to get up to gauge.

    How about using some concrete bricks designed for between block and beam flooring at the edges. Not sure if they are called slips but they are about 30mm thick.

    Brick or block on edge for the first course.

    Clay roof tiles.

    A few big or tight joints

    At the risk of posting my rough as arse first few bricks down (On the hottest day ever, too!) I thought I'd show you guys what I ended up with:

    Cut down engineering bricks, and this brings me bang onto gauge and takes care of a slope too.

    Can anyone sanity check it and tell me BCO etc will be happy with it and my wall won't fall down?

    Why the hell didn't you just lay a brick or block on edge?

    To be honest, the main reason is I don't remember seeing your reply before.

    But, I'd still struggle with the slope as I had to thicken them up a bit on one end and I'd be a bit uncomfortable laying on the thin edge of a brick to be honest. I mean, it's a learning exercise but as long as it's structurally sound then I'm happy enough with how I've done it.

    But if I need to rip it up and start again, then I will!

    BCO will call the police, you will go to jail, then it will fall down ;)

    Otherwise it will be fine.
