BrickBlock Restraint Goal

• To act as an effective subsurface restraint for paver installations.
• To provide a metal restraint that can withstand powerful maintenance edgers directly adjacent to the installation.
• To allow irrigation head installation and resulting healthy grass directly adjacent to the paver installation.

*Application Overview

• BrickBlock paver restraint is set and anchored into compacted base using 3/8” x 10” spiral steel spikes.
• A setting course (3/4” to 1” of fines or sand) is laid over the compacted base. The setting course acts as a leveling course filling in the un-level portions of the compacted base.
• Pavers are laid on setting course with a thin layer of fines spread over the paver surface.
• The entire paver installation is vibra-pacted into place.
• Semi-compact backfill material adjacent to the completed paver installation providing additional support.

*Intended as an overview only, please refer to specifier/ manufacturer technical specifications.

NOTE: The typical installation is for the horizontal base of the paver restraint to face away from the paver (CAD drawing BB 1).
In the event the specifier / installer desires to face the base of the restraint under the paver, refer to (CAD BB 2). Although an “under paver” installation is perfectly acceptable, it can be slightly more difficult to achieve. If the compacted base does not fully support the restraint, the restraint can act as a “spring board” during the paver compaction process causing the outside row of pavers to “cup” (be raised) trapping water on the installation.

Anchoring

• 3/8” x 10” spiral steel spikes anchored 4” to 24” on center depending application.
• Anchor at ends of each section in addition to guidelines indicated below.
  Patios and Walkways 12” – 24” on center recommended
