Hello everyone!
We are now in our little house, and every day I spend several hours in the garden shoveling gravel and soil in various directions. But it’s about time we start thinking about supporting our terrain.
We need to retain a length of almost 42 meters (138 feet). The height will be about 1 meter (3.3 feet). We’ve already talked to a relative who is quite knowledgeable about this kind of work. He recommended simply building a formwork (50 cm (20 inches) deep into the ground and then 1 meter (3.3 feet) high) and pouring concrete into it—of course including reinforcement. This should be significantly cheaper than using L-shaped concrete blocks.
So far, so good.
However, I’m a bit hesitant about having to get all the OSB boards. We thought about pouring in 2 meter (6.5 feet) sections and then reusing the boards each time, but I’m still not really happy with that idea.
Now I’ve seen that formwork can also be rented. Somewhere I saw a picture of a curved formwork (which would also be a curve in our case). Does anyone have experience with this? Can anyone recommend something? Or do you have a completely different approach?

Hello Evolith,
that is really very affordable. Actually for a frost-protected foundation and a 1 meter (3.3 feet) high retaining wall. And all fully completed?
With 8m³ (10.5 cubic yards) of concrete and an area of approximately 12m² (129 square feet), that means the foundation would be about 66cm (26 inches) thick. That’s solid. I would at least do that myself, but with a company and at that price.
What type of bricks were specified? And what dimensions?
StevenThose are only the material costs. We requested a quote from our trusted building materials supplier.We also considered ordering the bricks from the hardware store. But I have some concerns about the quality, especially regarding the tolerances.
Hello Evolith
You need to level the bricks slightly in every course. Small plastic wedges are very helpful for this. Remove them again after pouring the concrete.
You can get the 24.5cm (10 inch) ones at any hardware store. If you go for 30cm (12 inch), it gets more difficult. Those are only available from building material suppliers.
I just bought 24.5cm (10 inch) bricks at Bauhaus for 2.95 each. You can also have them delivered by the pallet, which is cheaper.

I got my bricks from Raab Karcher, as I said 2 EUR each (5 full pallets) + 55 EUR for delivery. All prices include taxI thought Raab Karcher was only for businesses? At least, I can only place an order there with a business license.
Edit: Ah, you can also order as a private customer through their building materials retailer.
