The new Grassroof® is an overlay paving system that can be applied to new or existing flat roof structures. Grassroof® can be used as an extensive or simple-intensive paving layer, or as a base layer for intensive roof designs.
Grassroof units interlock together and can be laid either directly onto the roof membrane or via a foil backed polystyrene underlay.
A key element in simplifying the installation is the use with a Regarm moisture retaining blanket. The specification of Regarm will enable the omission of a soil layer reducing the volume of heavy bulk materials during installation.
Grassroof® with a simple ‘leave and lay’ format incorporates sedum turf; no soil is required, and these succulent plants can store moisture. When installed, the lightweight system weighs as little as 4.39kg/m² providing an easy to install and maintain green solution.
