Retention area Urban Mineral

Maximum daily load 10 and more hours

Envilope Urban load-bearing mineral compositions are used for highly loaded mobile roads and parking areas. This composition will not seal the built-up area and preserve the ability of the affected area to absorb rainwater underground.

Microgreen

Envilope Urban load-bearing partly green compositions are used for little-used mobile roads as well as parking areas with a requirement for minimal maintenance. The composition of Microgreen has a high ability to absorb rainwater underground and at the same time, due to photosynthesis, it also contributes to the stabilization of the local microclimate.

Max. daily load 8 hours
