Honeycomb panel for flat and green roofs – Water management and retention NIDAROOF

NIDAROOF is a honeycomb panel designed for temporary retention and drainage of rainwater on roofs. Its polypropylene honeycomb structure forms a lightweight, rigid reservoir that holds water temporarily before gradual discharge to the network or natural infiltration. Installed on a waterproofing membrane or beneath a green roof system, NIDAROOF supports sustainable rainwater management while limiting runoff flow. Easy to install and compatible with standard waterproofing systems, the panel also offers excellent compressive strength for use under gravel, paving slabs or extensive green roofs.
