Catalogue - Ground drainage PVC system

Adequa ground drainage PVC system consists of a double-walled circular corrugated grooved piping for shallow and deep buried (depths of over 4 m) drains. This drainage system is used for transit routes (roads, railways, airport runways), walls and dams, tunnels, landfill sites, agriculture, reservoirs, buildings, sports facilities, etc.

This double-walled (smooth on the inside, corrugated on the outside) is heat fusion welded during the continuous extrusion manufacturing process. The groove marking equipment, together with the corrugating, produces the grooves for the draining in the troughs of the piping, which are the areas of least thickness, thus minimising the retention as the water passes.



  • Road drainage (minor roads, main roads, railway lines)
  • Drainage for buildings (foundation, floors)
  • Agricultural drainage
  • Playing fields
  • Canals
  • Retaining walls
