HG 3920 - Extensive Aluminum Edge
Our Extensive Aluminum Edge is designed as a definite boundary between gravel / paver and growth media that allows the flow of water but not of the substrate.
Specific to this product, it:
partners with our 1” Drainage/Retention Board; the edging slots align directly with the height of the board to ensure an unrestricted flow of excess stormwater
utilizes a “smooth slide” design to make secure, invisible connections
has pre-fabricated inside and outside corners for ease of installation
prevents overly moist media conditions around the perimeter or in transition areas of the roof thus preventing anaerobic growing conditions
