Effective Storm Water Management

September 18th, 2019

With the recent levels of rain and bad weather reaching unprecedented levels, finding long lasting effective methods of managing storm water levels has never been more important.

The devastation caused throughout much of South East & South West England is well documented but it is vital that people realise that there are steps which can be taken to help reduced the future impact of storm water.

Green roof systems are extension of existing roofing spaces (and any sizeable flat open space) which involves a high quality water proofing and root repellent system, a drainage system, filter cloth, a lightweight growing medium and plants.

Wide Ranging Benefits

Green roof technologies not only provide the owners of buildings with a proven return on investment, but also represent highly effective opportunities for significant social, economic and environmental improvements, particularly in cities.

Storm Water Management

One of the primary benefits offered by the installation of a green roofing system such as our innovative M-Tray Modular Extensive Green Roofing System, is the fact that not only is it exceptionally easy to install, it offers long lasting assistance against the threat caused by excess storm water.

How Do They Help?

  • Water is stored by the substrate in a green roof and then absorbed by the plants from where it is returned to the atmosphere through a combination of transpiration and evaporation.
  • During optimum periods, such as the summer, depending on the plants and depth of growing medium, green roofs offer the potential to retain up to 75% of the storm water that falls on them. Even during the winter months they can retain between 25-40%.
  • Not only will our M-Tray green roofing system help to retain rainwater, it will also moderate the temperature of the water and act as an effective natural filters for any of the water that happens to run off.
  • Perhaps one of the most important benefits on offer is the fact that not only will they reduce the amount of storm water run-off, they also delay the time at which run-off occurs, resulting in a critical reduction of the stress placed on on sewer systems at peak flow periods.
