ABG Roofdrain Geocomposite
ABG Roofdrain is a geocomposite drainage and attenuation layer designed specifically for green roof systems.
ABG Roofdrain combines a high-strength HDPE core with water storage capacity to manage both drainage and moisture retention within the roof build-up. Installed beneath the growing medium, it helps create the ideal balance of water flow and retention required for healthy plant growth.
By allowing excess water to drain away while storing moisture within its core, Roofdrain supports plant health in both wet and dry conditions. Its lightweight and easy-to-install design makes it a practical and cost-effective drainage solution.
Typical applications include:
- Green roof drainage systems
- Extensive and biodiverse (brown) roofs
- Green bridges and green tunnels
- Water attenuation and SuDS systems
- Roof builds requiring combined drainage and moisture retention
Frequently Asked Questions
Roofdrain is used in green roof systems to provide both drainage and water storage, supporting healthy plant growth and protecting the roof structure.
It stores water during dry periods to prevent plants from drying out, while also draining excess water to avoid waterlogging.
It’s suitable for extensive green roofs, brown roofs, green bridges, green tunnels, and SuDS applications where drainage and attenuation are required.
Benefits & Features
- Lightweight system that reduces structural load requirements
- Prevents plants from drying out
- Assists in reducing roof temperatures through moisture regulation
- Prevents waterlogging by efficiently draining excess water
