Unilock U-Cara Sure Track Backer Corner 56 Ea/Pallet | 175BSTB211141

Key Features

• APPLICATIONS - design and build projects such as planters, steps, grill islands, pillars, seat walls, water features and structural walls reinforced with geogrid. U-cara is designed mostly for straight walls, but low curved planters can be made if needed
• CAPACITY - gravity walls up to 39" (1m). Geogrid reinforced walls up to 10 ft. (3m). Download the u-cara manual for detailed information on how to build almost anything
• RECOMMENDED BASE STABILIZATION - one layer of DriveGrid stabilization grid between subgrade and base material. Use under standard base or permeable base
• STANDARD BASE - min. 6" - 8" of 3/4" crusher run gravel (any road base standard in accordance with ASTM-D2940) compacted to 98% standard proctor density (SPD)
• ALTERNATIVE PERMEABLE BASE - min. 6" - 8" of 3/4" clear open-graded stone compacted to achieve full particle lock-up and consolidation. (clear open-graded does not compact but does consolidate slightly by rattling the particles together.)
• LEVELING - u-cara MUST be constructed on U-Grip base units or universal base pads. It will ensure improved accuracy and will make for a speedier installation. Additional benefits include long term structural integrity and an overall better appearance. Poured concrete leveling pads, reinforced with rebar, are also a great way to accomplish leveling, especially for larger installations. You must ensure that the concrete is poured and finished perfectly in order to achieve a good visual appearance
