Project Material drainage cell is available in both 20mm and 30mm configurations. Both sizes have been utilised in large scale projects around Australia with great success.

Designed and manufactured to the highest standards the modular system has become the drainage cell of choice for Architects, Builders & Landscapers for functionality and reliability.

Project Materials drainage cell provides a perfect solution for sub-soil drainage application such as creating successful roof gardens, planter boxes, laid underneath synthetic turf and behind retaining wall systems.

The 20 & 30mm drainage cell provides a uniform surface as well as an internal void space for effective draining of excess water.

The drainage cell has a unique diamond cup structure which provides water retention for passive irrigation and helps building a perch water table in the above soil profile for the vegetation to flourish in prolonged dry periods.

Both 20 & 30mm drainage cell is made from recycled Polypropylene and is inert to soil borne chemicals and bacteria. The shallow and effective drainage profile helps landscapers to make use of mature plants on roof garden which needs soil depth and water retention properties.

High Summer temperatures can cause thermal expansion in concrete and can cause waterproofing to crack, Project Material drainage cell system, due to its unique design and void properties help this heat to escape and hence reduce the risk of cracking, enhancing building life.
