Soft bendable PE material can be freely shaped into curves, circles and irregular outlines around tree pits, flower beds and walkways. The L-shaped structure effectively locks soil and gravel in place to avoid cross-contamination and stop grass root spread. Waterproof, anti-UV, crack-resistant and fade-proof under all outdoor weather conditions, its earthy brown tone blends naturally with soil, stone and timber for rustic garden aesthetics, ideal for residential yards, flower beds and park greening separation work.
