In Brazil's oldest historic center, taking the power grid underground without touching a single colonial foundation.
Replace the overhead wiring with underground infrastructure in Olinda — founded in 1535 and a UNESCO World Heritage Site — without compromising the colonial structures that define the city's landscape.
The Techduto NBR line made it possible to open shallower trenches that do not reach the historic foundations. The light, flexible material adapted to the center's irregular streets, minimizing intervention in the paving.
What the partnership delivered
- Historic center's aesthetics fully preserved
- Enhanced safety — no risk of collision, wind or trees over the wiring
- Greater reliability of the underground power grid
