For a green roof to function correctly, selecting the correct substrate is fundamentally important for minimising the load on the structure of the building and for ensuring the long-term health of the plants.
A growth substrate of Laterlite Agri Expanded Clay mixed with other components (peat, compost, etc.) offers many advantages:
Lightweight substrates that incorporate expanded clay are compatible with all climates and all plant types, e.g. sedum, grass, herbaceous perennials, shrubs, trees or horticultural plants (including urban vegetable gardens).
The substrate can be prepared in situ by mixing 20% – 40% Laterlite Agri with the other components, or can be supplied as a pre-mix ready for use.
LaterliteGreen is a ready-to-use pre-mixed lightweight substrate with optimised properties for green roofs and roof gardens. As required it can be delivered in big bags or pumped from a tanker truck. For further information please contact technical support.
