Installing the Keystone Verazzo Stone System is easy. Below are four photos depicting specific installation steps which are typical of all Keystone Retaining Wall products. The photos are followed by the three primary installation steps

Step 1:

Determine wall location. Dig a shallow trench for wall base. Place granular leveling pad material. Compact and level the base pad. Place and level the first course units. If grade changes along base of wall, create stepped leveling pad as required. Always start wall at lowest elevations, working to highest. Complete base course before proceeding with additional courses.

Step 2:

Place a 4” perforated drainage pipe behind 1st course then backfill first course units with clean granular fill material. Compact with hand tamper or appropriate vibratory plate tamper. Backfill and compact behind each course before installing

Step 3:

Starting at straight wall area, place units centered over joint of units below to form a running bond pattern. Build through curves in similar manner. Note: Depending on the radius being built, at curves, course bonding may adjust sideways. If stack bond occurs, (seams begin to line up) a unit may need to be cut accordingly to get back to running bond. Keystone recommends a minimum 7-8 radius to minimize any cutting required. Additionally the center pin position on the top of the unit should be used for most applications, especially walls with curves.

Step 4:

Finish the wall with installation of Universal cap units making cuts to accommodate curves where required and adhere them using Titebond adhesive
