Efficient Water Management with Natural Style
The Andesite Drainage Channel by Gramer Stones is a smart and sustainable choice for directing surface water outdoors. Its grey color, natural grain, and robust physical structure make it ideal for projects demanding both durability and visual integration. Designed for pedestrian and vehicular zones alike.
Sizes, Profiles & Material Features
Standard sizes include 12x30x50 cm and 15x30x60 cm, with groove shapes like U-profile, half-round, or V-cut. Available surface finishes include sawn, flamed, or sandblasted, all offering reliable grip and slip-resistance. Andesite is naturally low in water absorption, freeze-thaw durable, and resistant to UV and mechanical impact—a perfect material for long-term drainage use.
