Drainage-accumulating layers intensive green roof - planters. This is a very important segment of the overall system of an intensive green roof - planters. Proper planning and technically correct selection and installation of drainage-accumulating layers will give the result to your intensive green roof - planters, with all natural predispositions for normal growth and development of selected (crop) type of plants and will provide all the preconditions for the proper and smooth drainage of excess water from the waterproofing . To be more precise, without properly selected and built-in drainage-accumulation system, intensive green roof - planter would dry up in summer time, plants and vegetation would soon began to wither due to lack of water and moisture. In winter time, due to high precipitation, in the intensive green roof - planter, there would be an increased amount of water that would drain away difficultly and slowly, and would, in this case, produce to a weakening and drying of plants and vegetation. There are also other advantages such as rational ways of controlling consumption of water for irrigation, relief layers of waterproofing, breathability, which is very important for proper growth and development of plants, the possibility of natural self-regulation of the microclimate inside the intensive roof - planters and others.
