Are you looking for Nature-Based Solutions? Do you want to increase Bio-Diversity on your building? Drainages are layers that combine into green roof systems to enhance water retention or filtration, depending on extensive or intensive solutions.

Green roof drainages

DANODREN are high-density polyethylene nodular sheet (HDPE). In construction, drainage membranes are typically installed on top of a layer of gravel or other drainage material, providing a barrier to prevent water from seeping into the building or structure. They can also be used to protect building foundations from hydrostatic pressure caused by groundwater, and to prevent damage from freeze-thaw cycles. Drainage membranes are easy to install and can be customized to meet specific building requirements, including different levels of compressive strength, thickness, and drainage capacity. Overall, drainage membranes provide an effective and efficient solution for managing water and preventing water damage in construction projects, helping to improve building durability, reduce maintenance costs, and create a safer and healthier living environment.
