The ARIEL Corodrain Universal Valley Trough 3m is used to form an open drainage channel at the roof valley where two pitched roof slopes meet. Its design includes a sanded strip to assist with mortar adhesion, helping to secure the trough neatly in place during fixing.
This product is typically installed in both new and existing tiled or slated roofs to guide rainwater towards the eaves and reduce the risk of water penetration at joint areas. It is suited for projects seeking a straightforward alternative to lead valley troughs.
