In this project we combined two soil stabilization solutions: micropiles and soil nailing. The real challenge here was that no structure could go beyond the property limit.
That limitation really restricted many possible solutions, especially soil nailing. We tried several arrangements and lengths and we finally came up with a solution in which the whole area would be stabilized through soil nails of various lengths without touching the property limit and the tallest part of the slope would be also reinforced with micropiles.
The micropiles provided the extra strength the soil nailing couldn’t give to the slope due to the small distance it could be introduced. We also faced severe problems due to infiltration of water in the slope.
