Hi everyone!
I’m getting a bit desperate...
I need to create a slope towards the neighbor’s plot, from street level 0mm (0 inches) up to the end of the terrace at 120mm (5 inches). I’m digging here with a pickaxe, and the soil is stone mixed with clay.

I’m already quite deep below the natural ground level. Do I still need to dig down 80cm (31 inches) for frost protection?

Ideally, I would like to do some excavation, then set vertical reinforcement in concrete, and start building the wall.

So, after excavating quite deeply, I have poured the foundation.

I will start by laying two rows of the retaining wall blocks and then build the strips for the garden shed onto them. That will basically form a large L shape.
I just hope I can get the garden shed strips nice and straight!

Looks good, but more rebar wouldn’t have hurt.

Hmm, okay, now it’s too late. I was worried that it would be difficult to align the bricks. I have now dry-laid the first row and already had to shift them back and forth three times!

The rough layout is done beforehand, but don’t worry if you have to cut some parts the first time. I also had to cut a few myself. I placed planting rings but didn’t account for the quarter circle.

Do you have the formwork blocks with the half-round recess on top? If so, insert steel reinforcement there as well.

It will hold! Yes, for the horizontal layers, I will lay a full course on each row. Additionally, I can also place some vertically on the foundation.

Hello M4rvin

Get 12mm (1/2 inch) reinforcing bars. Measure the position of the concrete blocks. Drill 12mm (1/2 inch) holes about 10cm (4 inches) deep into the foundation. Then insert the reinforcing bars approximately every 30cm (12 inches). Let them protrude 40-50cm (16-20 inches) above. This way you’ll be on the safe side.
