Applications: All-round substrate that lends itself to both intensive and extensive green roofs and green infrastructure. Recommended for creating driveway lawns and roof gardens.

TerraMediterranea TMT is Harpo’s most versatile substrate, performing moderately well in all aspects. It is heavier than the other substrates in the TerraMediterranea range, but this is combined with good durability and stability performance (AASHO A1-a rated and CBR index certified). These characteristics make it particularly suitable for creating driveway lawns. It also has a more natural-soil-like appearance, proving particularly popular in the creation of rooftop gardens.

The Harpo R&D laboratory performs continuous monitoring on the production of TerraMediterranea TMLight substrate. Performance and tolerances are declared on an analytical and statistical basis according to a rigorous specific process defined by Harpo’s UNI EN ISO 9001:2015 quality management system. The substrate adheres to the UNI 11235:2015 standard.
