Description
The Contorno de Florianópolis project was devised to counter the congestion of the region’s increased road traffic. It comprised a new four-lane highway approximately 51 km in length, including viaducts, bridges, interchanges, and two (1.6 km long) tunnels. As the largest recent highway construction project in Brazil, this new BR-101 bypass road now diverts heavy traffic away from the Florianópolis metropolitan area, reducing congestion and improving traffic flow.
Products Used
Penetron was tapped by Arteris, the general contractor, to provide the waterproofing solution to protect the concrete structures of the highway tunnels from deterioration due to groundwater penetration (i.e., moisture) , chemical attack, and carbonation. PENEPLUG, a rapid-setting, crystalline compound, was first applied to stop active leaks in the tunnels. After proper preparation of the concrete surfaces of the walls, PENECRETE MORTAR, a crystalline waterproofing repair grout, was used to fill any gaps and to repair any cracks (wider than 0.5mm) in the concrete walls. PENETRON, a crystalline waterproofing material, was then topically applied to the finished walls to permanently protect the whole structure.
