Product applied: Concrete pipes for pluvial water with internal nominal diameters from 300 to 1500 mm –
Class PA-2.
Technical Solution: Pipes settlement over the bed of gravel and the embankment.
Advantages: Execution simplification and speed increase.

Product applied: Pre-molded Cellular Galleries (Staves) with dimensions of 4,50 x 2,50 x 0,25 x 1,00 m, meant to the channeling of the stream in the city of Barueri – SP.
Technical Solution: Internal channeling of the stream with bottom preparation and embankment of the pieces without swerving the water course due to the intense inhabitation occupation.
Advantages: Execution simplification and land moving decrease.

Product applied: Open section pre-molded Cellular Galleries (Channels) with dimensions of 2,00 x 1,50 x 0,15 x 1,00 m, meant to the open-air channeling of the stream.
Technical Solution: Continuous and consecutive pre-molded pieces embankment in short ranges to minimize the costs with supports and speed up the construction works. Narrow and very populous area.
Advantages: Construction works feasibility on account of the local interference and execution agility.

Product applied: Closed section pre-molded Cellular Galleries (Staves) with dimensions of 3,00 x 2,50 x 0,20 x 1,00 m, meant to the channeling of the stream and pluvial drainage.
Technical Solution: Execution of double-lined pre-molded staves embanked over the concrete bottom and dimensioned for a high depth of the embankment to respond to the hydraulic needs.
Advantages: Quick release of the embankment execution which has high depth and intense land moving.
