Sedum blankets, instant vegetation

Boasts a 90 per cent coverage with a broad variety of mature plants species, field-grown for a minimum of 12 months.  This full foliage canopy protects soil erosion and prevents lateral water flow. Comes in rolls and easy to install.

Engineered growing medium

Proprietary, FLL compliant, soil recipe preferred by vegetated roofing plants and especially formulated for rooftop application. It encourages microbial soil health, healthier plants, reduces runoff and eliminate irrigation and the potential need for synthetic fertilizers.








Stormwater retention can be further enhanced by Urbanscape®’s Mineral Hydro Cubes or Hydro Flocks.
