Application

For use in green roof applications to prevent drying out or waterlogging of growing media. Used to store large volumes of rainfall and significantly reduce surface water run-off.


The 60mm Roofdrain provides a high compressive strength drainage solution for installation beneath podium decks and landscaping designs. The core is typically infilled with pea gravel to provide a rigid sub-base and the upper side of the core includes perforations to allow water to percolate through to the channels on the under side.

Description

Extensive Green Roof comprises:

- Growing media:

ABG peat free media derived from sustainable, 100% recycled, UK sourced materials. Using a specifically developed growing media can help provide the right growing environment for the selected vegetation and also reduce the load on the roof. The growing media can also be adjusted to support specific design requirements like calcareous applications


- Vegetation:

Specifically selected to suit the final finish requirements of the client/ end user. On extensive green roofs, low maintenance varieties such as mosses, herbaceous plants, sedums wildflowers and grasses tend to be used.


- Geotextile fibre fabric:

Laid beneath substrate to prevent fines filtering through to voids below.


- ABG Roofdrain:

A drainage/ reservoir board which attenuates and retains the optimal amount of water for the success of the plants and biodiversity of the roof. The core is perforated to allow the excess water to drain through into the flow channels beneath, preventing pooling and over saturation of the plants. The product allows the storage of water within the cuspates of the HDPE core whilst facilitating the efficient drainage of any excess water away from the roof. This helps prevent the growing media from drying out during dry periods and from becoming waterlogged during wet periods. When used within a green roof construction it provides a versatile system for the collection of rain water at the base of the growing medium and for the prevention of water pressure on the structural waterproofing, whilst allowing oxygen and nutrients to get to the roots of the plants.
