RIWI® Tree substrate is very suitable as a planting space improver for trees in heavily burdened areas such as car parks and roads. The substrate solidifies the ground, but because of the presence of a kind of soil guard the pressure can be absorbed and divided, so that trees can grow well.
It is composed of various products, such as lava stones. Consequently, an optimal grow situation for tree roots is guaranteed with regard to root growth, air supply, capillary function and water absorbing capacity. Here, the tree substrate maintains sufficient capacity (CBR>50%) to guarantee long term robustness.
