The Gravelock Drain Bar is a high-quality perforated aluminium edge trim designed to provide secure, functional, and aesthetic boundaries for modular green roof systems. It ensures efficient drainage while separating vegetation from roof features such as drains, skylights, and parapets.
The Gravelock Drain Bar provides a robust edging solution for modular or tray-based green roof installations. Installed beneath the tray units or weighted with decorative pebbles, this lightweight, corrosion-resistant aluminium angle prevents soil or vegetation migration while maintaining free water flow.
Ideal for use along exposed roof edges or around roof penetrations, it can be mechanically fixed or simply ballasted where direct fixing is not suitable for waterproof membranes. Its design provides a clean, professional finish while enhancing both performance and fire safety through integrated pebble borders.
