Architect Frederic Tomat designed a light and airy structure that minimises the impact of greenhouse gases through various measures, including an innovative self-watering green roof and terrace solution from BMI.
Through the use of our advanced BMI Siplast Wateroof system, we were able to create a durable solution which supports beautiful flora through a simple water-retention system. Nidaroof alveolar plates helped to manage the rate of water flow by providing a stabilising substrate with an integrated honeycomb sheet that temporarily retains rainwater. For effective drainage of unused water, a separating geoface layer (Geoflow 44-1F) was installed between the highly resistant waterproofing membranes and Nidaroof panels. This simple system will help to sustain the green roof and ensures compliance with the strict Parisian water-dispersal regulations.
The vegetation was supplied as a pre-cultivated carpet created by an experienced landscape gardener. This beautiful natural covering was installed over the Wateroof solution on ribbed steel, anti-root, pre-vegetated watertight tanks.
