Hello,
we are currently planning the slope stabilization and want to use L-shaped retaining walls. The basement contractor would install the 30 meters (98 feet) that need to be secured for about €6,000 using L-shaped retaining walls (or masonry panels). Since we want to do as much as possible ourselves otherwise, we are considering whether it would be cheaper to do this on our own. I am wondering where it is most cost-effective to source these L-shaped retaining wall units.
Does anyone have experience with this?
Thanks in advance for the answers,

EveundGerd21 Oct 2015 17:44Instead of building a 2 m (6.5 ft) high L-shaped retaining wall, we opted for a gabion wall made of two 1 m (3.3 ft) high sections. Although it was a bit more expensive because the visible stones were all placed by hand and the finishing curve was constructed as a dry stone wall, the slightly higher cost was worth it.
Gabions can also be filled as a DIY project, which significantly reduces the costs. Setting L-shaped concrete blocks of that size… without an excavator?
Our neighbor had L-shaped blocks installed at various heights. The smallest is 40 cm (16 inches) high, the tallest is 2 m (6.5 ft). Without an excavator and wheel loader, this wouldn’t have been possible. Machine rental hours also cost money! The contractor needs to earn a living too.
I consider the initially mentioned price of 200 €/m² for a 2 m (6.5 ft) L-shaped block wall, including foundation and installation, to be realistic.

nordanney21 Oct 2015 18:24A height of 2m (6.5 feet) would be fine – but the 200€ referred only to half the height, which is 1m (3.3 feet)!
Oh God no, of course we also had an excavator. But it didn’t cost much for the two days compared to other expenses.
We also installed gabions on one side, including the base layer. According to the landscape gardener, it should have cost around 2.5 tons (2.5 metric tons), but we bought four used and two more new ones, and including the filling material, it came to just under 500 euros. Here’s a picture, but on that side it would have been too expensive because those are the higher sections and you wouldn’t even see the wall...

EveundGerd22 Oct 2015 22:27I will upload pictures tomorrow.
But here are the details already:
Length: 13.5 m (44 feet)
Height: total 2 m (6.5 feet), each gabion is 1 m x 1 m (3.3 feet x 3.3 feet)
I can also share how much lava is underneath. Excavation was done to a depth of 70 cm (28 inches) due to ground conditions.
