The Challenge
- Mountainous terrain challenge
- MSE retaining walls corrosion due to salts used in the winters
The mountainous terrain of The Colony posed a significant challenge to infrastructure construction on this popular ski slope. Mechanically stabilized earth (MSE) retaining walls were used and consisted of welded wire for face elements and primary reinforcement. Unfortunately, intrusion of deicing salts placed on the roads in the winter led to acceleration of the metallic grid reinforcement in most of the walls. As a result of the accelerated corrosion, it was recognized that the service life of the walls would be lower than that for which they had been designed.
