Description
The Metro of Fortaleza – known popularly as Metrofor – operates a light rail network comprising 4 rail lines and 53 stations, and bus transit lines, all serving the cities of Fortaleza, Ceará, and the surrounding suburbs. The new Fortaleza Metro East Line (Linha Leste) is 7.3 km (4.5 miles) long and has five stations, one aboveground (Tirol-Moura Brasil) and four underground (Chico da Silva Leste, Colégio Militar, Nunes Valente and Papicu). The new line connects the Metro network with the South and West lines, as well as the Parangaba-Mucuripe tramway and the Papicu bus terminal.
Products Used
A key part of the expansion of the Chico da Silva station was the construction of the 1-km long (0.62 miles) twin tunnels using a cut-and-cover method and cast in-situ concrete for the foundation slab, retaining walls, and tunnel roof. Supermix, the project’s ready-mix concrete supplier, added PENETRON ADMIX, a crystalline waterproofing admixture, to the concrete mix for all new concrete structures. The resulting construction joints of the base and roof slab were sealed with PENEBAR SW-55 swellable waterstop strips. All tie holes were repaired and sealed with a topical application of PENETRON, a cementitious integral crystalline waterproofing slurry, and PENECRETE MORTAR, a crystalline repair grout.
