Description

The product is a blend of lightweight aggregate and specially selected washed silica sand. The sand has been specifically sourced to give the substrate optimum drainage properties, which works well with the drainage needs of the green roof substrate whilst offering good levels of aeration.

Benefits of Green-tree Roof Garden Subsoil

Lightweight and easy to install
Lightweight soils are much easier to manage. They are easier to spread and work with. These soils benefit vegetation establishment due to their open structure.

High quality ingredients
Lightweight aggregate promotes strong root development, improves aeration and drainage. Silica enhances the strength and rigidity of plants to help reduce pest damage.

Optimal drainage properties
Drainage properties enable the water to move freely through, and be soaked up by, the soil and carried to the plant’s roots and stems for a healthy and established roof garden.

Good levels of aeration
With lightweight aggregate being incorporated into the blend, this opens up small holes and gaps within the soils structure to allow air, water and nutrients
to the plants.

Guaranteed quality and consistency
This blend of subsoil is high quality which provides added reliance to perform exceptionally on a green roof environment under strong and harsh weather conditions.
