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:

Technical drawing: slope stabilization with planting blocks, stairs on the left, tree on the right, terrain profile.


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!

Such slope landscaping will never be cheap. First, check whether it is even permitted. Then you can discuss possible solutions. Depending on the overall situation (extended slope or just a filled plot), it might be possible to use only gravel and geogrid.

The height and steepness definitely require a professional to plan and obtain approval, if necessary...

Car tires? Seriously? I’m not sure you’ll get permission for a special waste disposal site in a residential area.

They contain toxic substances that should not be released into the environment.
Which ones?

Limited polycyclic aromatic hydrocarbons (PAHs), along with zinc and sulfur. But overall, nothing extreme or that would lead to soil contamination.

About 10% of a tire consists of chemical additives such as plasticizers, vulcanizing agents, zinc oxide, butadiene, thiuram, polycyclic aromatic hydrocarbons (PAHs), 1-octanethiol,

The shoulder material is tested for pollutants, among other things due to tire wear, and must be disposed of if necessary.

For a wall like this, quite a lot adds up. Maybe current limit values are being met, but what about in 3 or 4 years? Where is the line between upcycling (reusing as a planter ring) and illegal dumping?

As long as there is no abrasion, I see only a low risk of any disintegration or leaching caused by water.

However, if there are small children in the house, I am a bit more cautious, since they tend to touch and even lick everything. That is why there are increasing warnings against making toys for children from used car tires. Overall, I would also prefer not to have old tires in the garden.

But that is not necessarily the topic here... 🙂
