  • Grading


The grades are based on the percentage of clear, defect-free wood in the board. With Premium Grade, each piece is individually inspected to ensure premium quality, durability and appearance. Visually, Black Locust is known for its knots, mineral streaks, checks, minor grub holes, and bark insertions. To ensure superior appearances, only the most appealing pieces qualify as Premium Grade. Sound included knots, 3″ in diameter and less, minor mineral streaks and small bark insertions are admitted to highlight characteristics of the Black Locust species. Checks less than 1/12th of the board length are also admitted.


Black Locust is rot-resistant due to its natural genetic makeup. Natural rot-resistance, water-resistance, and anti-fungal properties give Black Locust a lifetime of 50+ years. Its durability and strength make it an excellent and long-lasting landscape surface.

Heat Island Effect

The light color and material properties of Black Locust make it a cooler alternative to concrete and other landscape surfaces, thus reducing the heat island effect. The heat island effect is the difference in temperature between a developed area and natural area. The addition of plants or moss between the pavers can help further reduce the heat absorbed by the ground covering.
