100% gravel on mineral foundation - complete O2D system

Technical information on the mineral foundation for light vehicle parking with O2D MINERAL® system

Composition :
•  15 cm thickness: 2/20 mm or 2/32 mm crushed roadbed foundation
•  3 cm thickness: 4/6 mm or 3/8 mm crushed roadbed bearing course

Prepared base/sub-base (-23 cm in relation to level 0):
•  The requisite permeability below this foundation system is such that K > 10^-6 m/s
•  The load-bearing level required is such that EV2 > 40 MPa (EV2/EV1 < 2)
•  We recommend the installation of a permeable anti-contaminant geotextile membrane

This mineral foundation composition ensures both load-bearing capability and drainage. It is recommended that the thickness of the sub-base (for example, 20/40 mm crushed drainage gravel) should be adjusted and/or any other facility should be incorporated, if the natural ground surface does not possess the requisite infiltration properties, or for the satisfaction of project design requirements. The load-bearing level should be appropriate to the intended application.
