ProfiLine: drainage solution for green roofs
Green roofs are increasing in popularity as urban spaces incorporate green space to improve the living and working environment. Green roofs are beneficial also in reducing a buildings heating and cooling consumption as they are proven to naturally regulate a buildings’ temperature by acting as insulation.
Drainage of green roofs and ground floor perimeter gardens can be problematic because excess water can be difficult to manage during storms where quick evacuation is required. ACO’s ProfiLine is designed to protect buildings by collecting stormwater generated from the façade and water that has accumulated on the roof surface, specifically above the roof waterproof membrane.
In heavy storm conditions, ProfiLine acts as a conventional surface water trench drain. As the soil is saturated during these events, water will only be collected through the grate. During light or recent rain, water will permeate through the perforated channel walls and ProfiLine will perform as a sub-surface trench drain system. Therefore the bias of one function over the other will depend on rainfall conditions and soil characteristics. The result in either case is to ensure water is directed to the desired outlet for appropriate management.
