Applications & Installation

Boughton Lightweight Subsoil is available for all your green roof or podium projects. If the standard product does not meet any weight limitations, the subsoil can be blended to suit your specifications.

Boughton Subsoil can be laid to depths varying from 100 / 500 cm. The depth of substrate is determined by the planting scheme and the weight loading capability of the roof/podium which must be assessed by a qualified structural engineer.
