ᐅ Offer for Installing L-Shaped Retaining Wall Blocks for Slope Stabilization

Hello,

we received a quote from our garage construction company for installing L-shaped retaining walls for slope stabilization over 26 meters (85 feet). The installation will be done in 20cm (8 inches) increments, ranging from 2 meters (6.5 feet) down to 1 meter (3.3 feet), with approximately equal quantities at each height. Is a price of around 20,000 euros reasonable for this work?

Choose a different provider.

We paid a maximum of 2,800 euros for 7 meters (23 feet) all inclusive, but 2 of them were about 3 meters (10 feet) high, and the rest were staggered, each 50 cm (20 inches) lower. The company that poured the foundation also completed the work at the same time.

We had about 20m (65.6 feet) of 60cm (24 inches) high L-shaped retaining walls installed. This included excavation, laying gravel, compacting, embedding the stones in concrete, applying dimpled membrane, and then backfilling everything. The team took two days to complete the work, and it cost around 2000 euros. We had it done by a landscaping contractor.

Best regards,
Sabine

The price ranges for L-shaped retaining walls vary greatly. I had my quote verified here as well. It looks like we are looking at around €21,000 to €20,000 net for 54m x 1m L-shaped retaining wall. I have to accept the main contractor’s offer since no one else wants to do this tedious work. My gut feeling says my quote is at least €5,000 too expensive.

But it is what it is. At least I get everything from a single source, reducing the potential for errors.

Insane amounts!

I built my retaining wall by myself.

Bought nice gray hollow blocks, reinforcement steel, mixed the concrete myself because it had to be used quickly despite delays.

Four days of work for 30 meters (about 98 feet) cost me and a friend around 2,500. €500 compensation for my friend’s effort.
