Incorporating Lytag horticulture aggregate (Hortag) within the build-up can greatly reduce the loading on the structure as well as aiding in the moisture transfer.

Lytag as a secondary aggregate will omit the need for natural aggregate within the Green roof build-up while providing greater water dispersion and attenuation, a suitable medium for sustaining vegetation and reducing the overall weight.

Applications:

Intensive, extensive, or simple intensive green roof systems.

ISO 9001, 14001 and 18001 certificates, BES 6001 certificate (excellent rating).
