Aquamodul^®

The Aquamodul blue roof sustainable drainage system is designed to attenuate, control and manage rainwater at source, providing attenuation capacity within the flat roof or podium deck construction of a development that can be combined with living roof, solar PV and multi-functional mixed amenity finishes.

Utilising podium deck and flat roof space in this way means that the attenuation capacity required to meet Sustainable Drainage Systems (SuDS) best practice can be achieved without the requirement for land consuming ponds and retention basins, or the challenges of constructing large and expensive subterranean geocellular rainwater attenuation tanks.

Aquamodul blue roof systems are designed to slow the release of rainwater into the drainage system and to discharge the water completely from the roof within a 24-hour period. They comprise two key components; a drainage geocomposite system with integral filter geotextiles and a series of restrictor chambers, and a restrictive flow outlet system.

Aquamodul blue roof sustainable drainage systems are designed for use with Axter Force^® Dalle roof waterproofing systems in a warm, cold or inverted roof construction. Aquamodul blue roof systems are also suitable for installation in conjunction with Axter’s unique Wilotekt^®-Plus Hot Melt structural waterproofing system in a cold or inverted roof construction.

When designing inverted warm blue roofs advice provided within BS 6229 : 2018 and the National Federation of Roofing Contractors (NFRC) technical guidance note for the construction and design of blue roofs should be followed.
