The NDS EP-1850 root barrier panel is an 18" tall, rigid interlocking panel that redirects tree and shrub roots downward — protecting sidewalks, driveways, slabs, curbs, and utilities from heave and cracking.

The 18" depth makes the EP-1850 a versatile, all-around choice for shrubs and small trees, balancing solid root redirection with easy installation. Molded vertical ribs guide roots deeper into the soil profile instead of toward hardscapes, and the panels interlock to form a continuous barrier you can route around trees, planters, and hardscape edges without any special tooling.

These panels are ideal for applications where the barrier must be installed close to the tree, such as sidewalk cutouts and tight planting areas. The molded ridges on each panel direct tree roots downward and deeper into the soil rather than allowing them to spread out shallow near the surface. Beyond protecting nearby hardscapes, this is the real advantage of a ridged panel: by encouraging a deeper root system it reduces the risk of tree tip-over — a common problem when trees are planted in tight areas and develop shallow, unstable roots.

Each panel measures 18" x 24" and ships in a pack of 25, providing 50 linear feet of coverage per pack. Made by NDS for fast, reliable, long-term root protection in residential and commercial projects.
