Applications & Installation

Boughton Semi-Intensive 2 can be laid at depths down to 100mm. The substrate will support varied planting. Boughton Semi-Intensive 2 is often used where increased levels of biodiversity are desired. Biodiversity is achieved by laying the substrate at varying depths across the roof, this in turn allows for different planting schemes across a single roof.

Boughton SemIN 2 Green Roof Substrate meets and exceeds all present GRO guidelines. The depth of substrate is determined by the planting scheme and the weight loading capability of the roof which must be assessed by a qualified structural engineer. Our substrates can be delivered in any required format. This includes 25ltr and IBC Bulk bags. Or loose tipped as required
