ᐅ Use L-shaped retaining blocks for slope stabilization.

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,

I just looked up one of our quotes from last year. The price for 60mm (2.4 inches) blocks including frost protection, installation in concrete, and sealing was €57.70 per meter, and for 80mm (3.1 inches) blocks it was €82.50 per meter (before price negotiations). Prices are gross and include a proper invoice!
Therefore, I still believe that your €200 was quite expensive.

I don’t see any gravel. We had it included for load case 5, how about you? What earthworks were involved, or were they separate?

The 200 euros per linear meter also correspond to the quotes we received. However, our wall had a sloping height.
We (or rather my husband and fathers) did it ourselves. Partly with large L-shaped blocks (up to 2 m (6.5 ft) high) and partly with a poured concrete wall. The materials were sourced from our trusted building supplier.

Oh, by the way... Compared to the quote, we paid only a fraction of the material costs. But it was also really tough work.

For us, it was all-inclusive, including all earthworks. I probably should have added that excavation was done, backfill gravel was placed and compacted, and only then were the concrete L-shaped blocks set. Don’t ask me about any specific load case; with our small 60cm (24 inches), I don’t really care – after just over a year, not a single block has moved even a millimeter. (:
