Installation Steps for VERSA-LOK Standard, Cobble and Accent

The following materials are essential to ensure proper performance of your VERSA-LOK Standard, Cobble or Accent wall:

• For your leveling pad, you will need a crushed-rock base material. Typically, this is the same material used for road base aggregate. You will top the leveling pad with a layer of sand.
• For drainage behind your wall, you will need three-quarter-inch clear, free-draining angular gravel aggregate.
• You will also need a supply of clean soil for backfill. This might be available from your excavation.
• Depending on the height of your wall, you may need a perforated, minimum 4-inch-diameter drain pipe to collect water along the base of the drainage aggregate and quickly move it away from the wall.
• You will need VERSA-LOK Concrete Adhesive and a caulking gun to bond your cap units to the top of the wall and to bond partial units that can't be pinned.
• Depending on how much your wall needs to support, you may need some Versa-Grid geogrid soil reinforcement, a utility knife and stakes.

Ground preparation is a critical step to ensure the performance of your wall.

To prepare the site for installation, you will need to excavate a 24-inch-wide trench deep enough to accommodate a 6-inch crushed-rock leveling pad, plus the embedded below-grade courses.   

If the grade in front of the wall is level, one-tenth of the exposed wall height should be embedded below grade. When special conditions exist, such as slopes in front of walls, shorelines or soft foundation soils, additional embedded courses may be required.
