In this railway gallery, located in the town of Benevento (Italy), water had leaked through both the vault and the side walls. To solve the problem, a waterproofing solution was chosen for the gallery, using Uretek Water Barrier® technology.
The gallery had a single lane, with a length of about 340m and a height of 4.5/5m, built with preformed stone blocks joined with cement mortar.
Leaks from the vault posed a problem with the overhead power line. Previous attempts had been made to block them with osmotic mortars, but the problem could not be solved.
Thanks to Uretek’s leak detection solution, the problem was solved quickly, safely, economically and minimally invasively.
The intervention was planned with the objective of reducing the leaks in the vault by about 3/3.2m, with a total linear development of 100m. A total vault area of 315m² was treated in 24 days. The work was carried out exclusively at night, so as not to interrupt rail traffic.
Uretek’s Water Barrier technology was used, which combines the expansive resin with a saturating gel. The resin seals the larger cavities, while the gel provides complete saturation.
