A new family of geosynthetic products , consisting of modular and three-dimensional units with high compressive strength, which are used in the  field of collecting, convey, storage, treatment and waste of stormwater from domestic and industrial use

The main advantages of using the GRAF devices are:

Easy assembly and installation even in hard to reach areas (light and easy to compose each other).

Large flow rate  (larger than any other composite for drainage present in the market ).Possibility of burying structures even in areas stressed by heavy static or dynamic loads (until 60 ton)

Greater flexibility of use, thanks to its modular design, adaptable in shape and size in many situations.
