Drain Cell

A drain cell is a type of structural drainage module composed of high-density polyethene (HDPE). Drain cells are modular and interlocking, allowing them to be readily put beneath a variety of surfaces, including green roofs, planter boxes, plaza decks, basements, and sports fields.
Drain cells may be used to generate green roofs, which are vegetation-covered rooftops. Drain cells aid in the drainage of plants while also protecting the waterproofing layer beneath.

Planter boxes made with drain cells allow excess water to drain away, reducing root rot.

Plaza decks: Drain cells can be utilised to construct plaza decks, which are normally paved with concrete or stone.
