Technical information on the fertile foundation material for light vehicle parking with a grass/paver infill

Composition :
•  15 cm thickness: TP GREEN soil and stone foundation material
     o 75% crushed material of particle size 20/40 mm
 o 25% organic substrate (topsoil/washed sand/compost) of particle size 0/10 mm
•  3 cm thickness: LP GREEN fertile bedding course
     o 60% crushed material of particle size 4/6 mm
     o 20 % topsoil/loam mixture of particle size 0/10 mm
     o 20% sand of particle size 0/4 mm

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 fertile foundation material composition ensures both load-bearing and drainage capabilities, and provides the requisite nutrients for the effective rooting of grass. 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.
