Product description
Platon DE25 is a studded sheet with formed cavities and channels. When applied to
green roof construction, above a root protecting layer and below a filter fabric,
the cavities are able to store water, which percolates through the soil from the
surface vegetation. Water rising above the level of the interconnecting channels,
is distributed between cavities. Drainage slits through the channels allow excess
water to drain through to the gap below (created by the studs), so that drainage
takes place above the root protecting layer across the flat roof. The product
thereby creates both a drainage layer and water storage layer in the construction
and secures appropriate aeration for plants' roots as well.
