Substrates of green roofs have a great drainage effect and high water retention capacity and they comply with any type of ecological roof. Manufacturers whose materials we use for landscape works are well known all over the world. We already had some common projects, and results were reliable and spectacular. If you choose us, the quality of building elements is doubled by the qualified human professionalism. Our team is well experienced in the use and maintenance of all building elements of a green roof. We can build extensive vegetation on industrial halls, intensive green terraces on office buildings, we can also create recreation and relaxing areas, intensive green roofs for high pedestrian traffic on the top of shopping malls, and many other ecological solutions. Thanks to the competence and professionalisms of our team, all materials used are compatible. Protection and filtering layers, drainage of the green roof, substrate for vegetation together with control boxes, delimitation elements, evacuation gutters are key components of a green roof system.
