Hello Team - Quick Question: A project in Las Vegas requires a number of very long retaining walls integrated into the site. Will we be more successful reducing embodied carbon with a block wall than a precast wall (given progress in the block decarb market and low embodied carbon grouting options, etc.)? That is our current assumption, but we are interested in any advice the CLF community can share. Thank you!
I don’t know, but have you looked at a gabion wall?

Thanks. My team tells me we need solutions with more load bearing capacity at these locations. We have been offered precast mechanically stabilized earth systems and/or CMU systems.
Your suggestion got us thinking about similar options.
We are now looking at TerraTrel® Wire Mesh MSE Retaining Walls.
Note that it is a MSE system but without the precast: For permanent solutions, a column of crushed stone is placed between the wire mesh and geotextile to protect the geotextile from UV light: TerraTrel® - Geoquest USA
