Greenroof
Together with Tref EGO, PULL has developed a lightweight roof gardening substrate, consisting of a special soil mix with Perlite as an additive. During the production process. a porous, white grain with a low volume weight, which is characteristic for the roof gardening mix, results at very high temperatures. The weight of this mix is approximately 275 to 300kg per m3. When saturated, the weight is between 500-600kg per m3. Greenroof is an environmentally-friendly natural product and is RHP certified.
The perfect capillary action and good drainage create an excellent substrate on roofs. Greenroof creates a water buffer capacity that the root network can rely on during dry periods. For roof gardens at great height, Greenroof substrate is delivered in big bags, which are easy to deliver on site with a crane thanks to its low weight.
