GrasCell® Drainage Cell

Lightweight Drainage Cell

A high-performance modular drainage cell system designed for sub-soil drainage, green roof drainage and planter box drainage applications. The structural drainage cells create a continuous void drainage layer, allowing efficient water flow while protecting waterproofing membranes and supporting healthy soil conditions for landscape planting.

​

These drainage systems are widely used in extensive and intensive green roof systems, rooftop gardens, podium decks, planter boxes and landscape areas where effective sub-soil drainage and waterproofing protection are critical. The modular drainage cell structure helps prevent water stagnation, improves aeration of planting media and ensures reliable water discharge beneath soil layers.

​

Engineered with high compressive strength, the GrasCell® DC drainage cells can withstand structural loads while maintaining consistent drainage performance. Available in multiple heights such as 20mm, 30mm and 50mm, the system provides flexible solutions for green roof drainage layers, planter drainage systems, rooftop landscapes and sub-soil drainage systems.

​

Manufactured from 100% recycled polypropylene, the GrasCell® DC Series delivers a sustainable solution for drainage systems, green roof drainage layers, intensive roof garden systems and waterproofing protection layers in modern urban developments.
