Key Features

• Capacity - walls upto 2 ft. (60 cm) in height and hardscape features up to 4 ft. (1.2 m)
• Recommended base stabilization - one layer of DriveGrid™ stabilization grid between subgrade and base material
• Standard base - minimum 6 in. - 8 in. of 3/4 in. crusher run gravel (any road base standard in accordance with ASTM-D2940) compacted to 98% standard proctor density (SPD)
• Alternative permeable base - minimum 6 to 8 in. of 3/4 in. clear open-graded stone compacted to achieve full particle lock-up and consolidation
• Levelling - levelling retaining wall blocks directly on top of gravel is tedious and generally does not yield the best results
• Connection - lineo has small spacer strips that are placed between the blocks during construction to create a 3/16 in. (4 mm) gap between units
• Handling - handle carefully so you don't chip the nice crisp edges
• Coping - this wall does not require coping, but coping is generally used to complete the installation visually
• Packaging: 3/Layer, 21 Unit/Layer, 63 Unit/Bundle
