Flexible Design using Aquadrain 25
Drainage is an essential part of any roof garden design. If there is too much water within the installation, root rot is likely to become a problem, and if there is too little water there will be poor vegetation growth. It is finding a good balance between the two extremes that leads to a healthy roof garden.
By using Aquadrain 25 as a roof garden drainage layer, green roofs are given the flexibility to perform both water drainage and water retention. Unlike other drainage solutions, Aquadrains robust structure, high void ratio and extreme loading capabilities do not restrict design. In fact, it is quite the opposite, with Aquadrain successfully able to deal with many drainage related problems whilst also being able to cope with demanding loadings.
Aquadrain 25
During storm events, roof gardens must be able to quickly deal with rainfall and absorb it as quickly as possible. Due to its 95% void ratio Aquadrain, 25 is able to deal with the most demanding, sudden downpours and improves the overall retaining ability of the green roof. Each Aquadrain 25 plate is capable of retaining water within its structure which helps prevent topsoils from drying out during periods of warm dry weather. By storing this water within a void beneath the soils, plant roots are protected from roof rot without compromising plant growth.
During dry periods when the plate is not storing water, Aquadrain 25 becomes an aeration layer. Aeration is an essential part of roof garden design and is fundamental in promoting optimal vegetation growth.
