Light expanded clay aggregate (LECA) is a light inert material. It provides a low density drainage layer in planters and can be added to growing media to reduce bulk density and to enhance drainage.
LECA is ideal for:
- Low density drainage layer in pots or planters where point loading is critical such as on roof gardens
- As an additive to growing media to reduce bulk density, for chimney relining, for under floor insulation & for Bio-Filtration.
It is available in loose bulk loads and 0.9m3 bulk bags
