The technical studies carried out indicated that the best solution to the problem presented, among others found on the market, would be two gabion retaining walls complemented by a drainage system with a hydraulic ladder made of Reno® PoliMac® mattress. The job also presented the challenge of transporting all the construction material to the work front along a narrow path that could not accommodate large lorries and equipment. Despite this challenge, the team was able to complete the job in a short space of time, guaranteeing the effectiveness and safety of the project.
