ᐅ Costs for Retaining Wall Made of Formwork Blocks

Hello everyone!

After unfortunately being let down at short notice by two landscape contractors, a potential replacement came by today for our project to build a retaining wall along our property boundary. He also brought a quote that made me think: For constructing the wall (about 23m (75 feet) long and 1.2m (4 feet) high), he estimated 12,000 euros.

The quote includes:
- Foundation work (80cm (31 inches) deep, including reinforcement steel)
- Setting formwork blocks (including reinforcement steel)
- Concrete filling
- Lawn edging stones as the "top row," allowing the formwork blocks to be covered with 25cm (10 inches) of soil
- Waterproofing on the built-up side to prevent moisture penetration

Since I’m completely new to landscaping construction, I would appreciate your feedback on whether this is a (too) expensive quote. The construction site is in Bavaria/Nuremberg.

The other landscape contractors’ quotes were in a similar price range, but for a (higher quality?) version using wall panels.

Silly question, but how are the lawn edging stones supposed to be fixed?

I assume the landscaping contractor meant the L-shaped stones. At least he mentioned casting the leg onto the top formwork stone with concrete. Maybe it was just a "language barrier" issue.

Anchors are, of course, planned. I just left them out so that the basic structure of the wall with the lawn edging stone would be clear.

That’s a relief 🙂

Reinforcing bars are placed horizontally and vertically inside the formwork blocks, with the vertical bars extending into the foundation (at least 50cm (20 inches) deep).

I assumed that.
