Aluminum Edging Systems

Installation Instructions for Stable Edge

Excavate by removing surplus soils and all unstable sub base materials.  Compact sub grade to 95% proctor density test.  Next, backfill excavated area with appropriate aggregate material.  (Please refer to ICPI standards or architects specifications to achieve an accurate base mix.)  The base should be no less than 4"-6" for pedestrian applications, 6"-8" for driveways and light vehicular traffic, and 8"-12" for heavy vehicular traffic.  Compact base in 2"-3" lifts to achieve proper density.  Ensure there are no elevation variances greater than 3/8".  It is equally important to extend the compacted base at least 6"-12" past the edge of the pavers.

Next, screed concrete sand over the base to a uniform thickness of not less than 1" and not more than 1 1/4".  Do not fill depressions with sand.  At this point you can install Stable Edge on one side to work as a guide during installation.  (Please note that the edging should be installed on the aggregate base not the screeded sand.)  Then wait till pavers are installed to put the final side of Stable Edge into place.  Some contractors choose to install the edging first and to use the restraint as a guide to work from, others install the edging after all the pavers have been set.

Install paves using the "click and drop" method while making sure that the pavers are 1/4" higher than the desired final grade.  Sweep fine sand into joints.  Make several passes with a plate compactor with no less than 3,000-5,000 lbs. centrifugal compaction force and operates at a frequency of 80 to 90 hertz.  All the time sweeping fine sand into the joints.  Make at least two passes, alternating the path of the compactor each time.  Sweep up all remaining sand and your installation is now ready for use.  Please refer to the standards set by the ICPI for more detailed specifications.
