Keep roots where they belong and protect your hardscape with the Convivium Tree Root Barrier Roll. Made from recycled high-density polyethylene (HDPE) at a sturdy 60-mil thickness, this heavy-duty barrier is designed to stop aggressive tree, bamboo, and shrub roots from lifting sidewalks, cracking driveways, or invading patios and garden beds. The flexible roll design makes installation simple for both homeowners and professionals. Just dig a trench, unroll the barrier, place it with the smooth side facing the roots, and backfill. The material cuts cleanly with a utility knife, so you can easily customize the length and shape to fit tree rings, straight runs, or curved landscape borders. Engineered for long-term underground use, our recycled HDPE is resistant to corrosion, puncture, and soil chemicals, and will not rot like wood or degrade as quickly as thin plastic. By redirecting roots downward instead of outward, the barrier helps protect sidewalks, roads, foundations, septic systems, irrigation lines and more, while keeping your lawn edges and planting areas neat. Available in multiple heights (12in, 17in, 24in) and lengths (15–20ft), all at 60-mil thickness, you can choose the right depth for different climates, soils, and planting distances. Whether you’re controlling bamboo rhizomes, guiding tree roots, or creating a clean garden edge, the Convivium root barrier provides a simple, effective, and durable solution for modern landscaping.
