Discover the amazing properties of Kik Mix ROOF substrates.


Water supply

According to the FLL guidelines, the water content of substrates used on extensive roofs should be within 20-35%, and for intensive ones 45%. It is also important that the soil has the ability to re-wet after drying.

Supply of nutrients

The limited depth of the vegetation surface on the roof does not provide enough nutrients, so it is important to provide the right amount of organic matter and exchangeable cations.


Oxygen supply

The moist substrate should provide oxygen access for plant roots. It must not cause complete drying or conditions that cause rot and die plants.



The FLL guidelines specify acidity for substances at the level of 6-8.5 pH and for intensive 6.5-9.5 pH. The composition of the substrate should protect against changing the reaction. Otherwise, this would lead to a lack of access to some nutrients.


Space for roots

The substrate must be stable to allow proper rooting of plants and to protect against adverse climatic conditions.


Resistance to kneading and settling

The proper mechanical composition as well as the shape and surface of the grains should ensure the best effect that is resistant to trampling and maintaining the desired structure for a long time.


Resistant to erosion

The substrate must be stable to allow proper rooting of plants and to protect against adverse climatic conditions.


Low flammability

During the warm months, the substrate is exposed to drying, so you should limit flammable ingredients. Proper fire protection of buildings requires the determination of the fire resistance class of substrates.
