ᐅ Slope Stabilization – Concrete Blocks or Car Tires?

Hello,

I want to stabilize the slope on my property (27m long) to create a usable, additional level.
My current plan is to stabilize only about 10m of it, since that area is the most important to have level.
This would give me a nice flat area about 4.1m long (13.5 feet).

I am looking for the most cost-effective solution for a steep embankment.
See the picture:

Someone told me that using old tires is the cheapest option and then planting ground cover on top.
But somehow I find that a bit odd.

What do you think?
Thanks!

For an even slope, you would need tires of the same size; otherwise, it will turn into a patchwork wall. Clearly, the tires would only cost 50-100€ (about 55-110 USD). But the cost of the entire slope collapsing, since the tires probably won’t hold, is not worth it ;-)
With the incline you’re considering, I would only trust concrete and steel in the planter blocks… if at all. A solid concrete foundation, then stacking the blocks in rows and pouring concrete. However, you also need to make sure to include proper drainage.

4 meters (13 feet)? In that case, planting rings are the last choice.

Has a structural engineer reviewed this?

How much further does the terrain extend? It might actually be simpler to just shift the current slope by about 4.10 m (13.5 feet). This way, you would only need excavation material. You can usually get that for free if you look around a bit. The top layers you would then purchase directly from the landfill.

A 4.5 m (15 feet) "wall" is definitely no small matter.
