Lightweight Green Roof Substrate

Lindum’s Extensive Green Roof Substrate is a blend of 100% recycled crushed brick (2-5mm) and green waste compost (0-10mm). The specially matured and graded recycled green waste compost provides optimal stability and minimal leaching of organic matter and nutrients.  The compost is mixed with carefully selected and graded clay aggregate made from recycled UK-sourced clean brick and tile.  The substrate has an air-filled porosity greater than 20% v/v to provide good drainage, strong root action and robust healthy growth.  Available in 1m3 tote bags, 25 litre heat-sealed bags, or in bulk, Lindum’s Extensive Green Roof Substrate provides a high quality green roof growing medium with green provenance – i.e. peat-free derived from 100% recycled UK-sourced materials.
