A lot of flat roofs are loaded with roll gravel. Among other things, the rolling gravel prevents the roofing from blowing up in high winds or storms and provides protection for your roof against UV radiation. LDG's ambition is to make its roofing gravel completely circular.
The technology for blowing (when building up) and extracting (when dismantling) roof gravel already exists. Only for washing the gravel, so that it is ready for reuse, there is no solution yet.
LDG and its project partners want to find out together which installations are needed for this, so that in the future roofing gravel can be recovered indefinitely.
In this way, the team is providing a valuable component in the construction of fully circular, non-glued roofs.
