Roofs that
are measured,
not just planted.
Six vegetated assemblies, each specified against a number an engineer can hold us to: saturated load, retained rainfall, wind uplift, panel yield. Built in Ontario since 2006.

New names. Same assemblies.
Every product was renamed in 2026 when we split the range by what it is engineered to do rather than how thick it is. Nothing was discontinued and no build-up changed without a revision note.
Holding a drawing that calls out V-Lite 100 or ED-300? Type the old name and we will tell you what it is now and what changed with it.

We stopped selling depth and started selling outcomes.
Sized to a hydrograph
Stormwater systems are specified from the civil release rate. Depth is an output of the calculation, not a product choice.
Habitat that is audited
Meadow roofs ship with an ecoregion seed schedule and a two-year establishment audit, so the biodiversity claim survives handover.
Load on the drawing
Saturated load, wind uplift and fire class for every assembly live in one table the structural engineer can pull before design development.
