ᐅ Build a retaining wall approximately 2.5 meters (about 8 feet) high.

Hello,
is it possible to build a retaining wall about 250cm (8 feet) high using concrete formwork blocks, so that the ground on top can be driven over by a car without the retaining wall breaking or shifting?

I was thinking of concrete formwork blocks measuring 50 x 25 x 17.5cm (20 x 10 x 7 inches)... of course reinforced with steel rebar and fully filled with concrete.

Phew, 250cm (98 inches) height and then the heavy load from backfilling and cars.
I would only do this with the involvement of a structural engineer.

Yes... there is about a 200cm (80 inches) difference in height... I want to set the bottom row of stones into the ground and then leave about 40cm (16 inches) as a wall above the terrain.

At the moment, there is a slope there, but I don’t like it. In the photo, you can see the slope quite clearly.

I also believe that nothing can be done without a structural engineer...

A car weighs at least 1 ton (1,000 kilograms)

always going on and off there...

Hello Saarländer,

17.5cm (7 inches) shuttering blocks leave you with about 9cm (3.5 inches) of concrete. Are you willing to take that risk?
I also wouldn’t install 30cm (12 inches) blocks without a structural engineer.
In that case, I would either fully form a 30cm (12 inches) wall or use L-shaped blocks designed for that purpose. However, L-shaped blocks are very expensive and you can’t install them yourself.

I have also considered using L-shaped concrete blocks, but such a wall can quickly cost around €25,000.

I need to consult a structural engineer to determine what support is needed and how to implement it.
