Height 500x500mm Water Storage and Drainage Board For Green Roof

Product Description

Storage and drainage board is made of polyethylene plastic injection molding. It is a new drainage material which integrates drainage and storage functions. It also has many functions such as water storage, drainage, air permeability, heat preservation and insulation, root prickling (preventing plant roots from destroying concrete structures) and so on.

Specs:

Manin features:

√ Water storage and drainage-Construction a drainage channel and water storage dimple with a certain three-dimensional spatial support.
√ Big load capacity- It is made of polymer materials, the anti-pression strength is more than 400kpa at most.

√ Heat insulation function- high-density polyethylene (HDPE) has good water resistance, heat insulation, high strength.
√ Water guiding function- the size of the gap between the protrusions of the drainage board determines the drainage capacity and the thickness of the air layer. Membrane and shell continuously form an independent space, liquid can flow inside.

√ Prevent puncture of plant roots- the HDPE is very strong can preven puncture of plant roots.
