Case 4 Soil retaining wall

LCA Studies

The use of Geosynthetics leads to lower impact in all categories:

  • ~ 75% reduction of non-renewable cumulative energy demand (CED).

  • ~ 85% reduction of cumulative greenhouse gas emissions.

  • Every 3 linear meters soil retaining wall (3 meter high) saves 30,000 MJ eq, which is equivalent to the energy consumption of one household per year.

​

At the same time, the use of geosynthetics generate cost savings (see graph below)
