soil filter

soil filter

The soil filter is one of the layers used in the roof garden in order to prevent the soil from passing to the lower layers. This layer is placed on the drainage layer, which is responsible for collecting water, and prevents the soil from passing and transferring to the drainage layer.

Features and benefits of soil filter

This layer allows water to pass through itself to collect water in the drainage layer, if other materials remain on it and prevent it from passing to the drainage layer.
High mechanical resistance and resistance to acids, which makes this layer ideal for this sector. Because after the implementation of the roof garden, access to the lower layers is not possible or it is difficult to access them, therefore, the soil filter layer must have sufficient resistance against all kinds of physical and chemical damage.
