GraveLight is a material obtained from the expansion of amorphous silica and used as a lightened subgrade for pavements or as a compensating layer. It has a coarse grain size belonging to a single grain size class (10-60 mm). It absorbs very little water so it is very light. GraveLight is placed above the MediDrain drainage panel and below the MediFilter MF1 geotextile filter.

Properties

• Mechanical strength that can be calibrated according to the degree of compaction (in case of green roof or pedestrian or driveway surfaces)
• Lightness
• Neutral PH

Uses:

For green roof applications and planters where it is necessary to lighten the stratigraphy

For green roof applications in multilayer systems where bulk drainage is opted for

For plugging the drainage layer, below the MediFilter MF1 geoextile filter, in cases where it is necessary to increase the compressive strength of the drainage panel or achieve greater thicknesses
