They are products used to transport or transfer liquids from source to final destination like concrete pipes, box culverts, grease traps, inspection chambers, grids, trenches and the rainwater drainage structures.

Concrete pipes are the most commonly used. They are a highly reliable and lasting solution for infrastructure jobs, because they offer more safety and protection to the environment. They are appropriate for safe distribution systems of water supply, irrigation, rainwater, highways and airport drainage systems, sewage collection urban networks.

Through state-of-the-art technology application such as modern equipment automation systems, the use of high strength concrete, new materials for concrete, or new geometric setups, the concrete pipes undergo continues enhancements in performance, durability and mechanical properties, with better performance in the systems. Currently, the systems have circular, elliptic and rectangular section pipes.

The concrete pipes durability is recognized as the main advantage, because it is one of the most critical factors for the specifiers in a project. Environments comprising low pH (acid) soils, never cause problems. Also the geometric setup options are studied to fight aggressive conditions and extend the useful life.
