ACO unveils DUNE®, its new gutter grid

The geometry and undulating design have been specifically designed to create a real barrier to the flow of rainwater runoff and thus improve drainage efficiency. An innovative design in both its shape and its performance. 

With a 13 mm slot width and a 30° chamfer, DUNE® ensures rapid passage of surface water for a dry floor even after heavy rain. 

Due to its high absorption capacity (up to 518 cm²/m for size 300), this new range of grids is particularly suitable for the drainage of large areas, urban spaces and stabilized verges. It benefits from a resistance classification ranging from C250 to D400.
