How to Install Redi-Rock Wall Systems

When it comes to installing Redi-Rock retaining walls and gravity retaining wall systems, there are a number of variables, as well as, engineering characteristics that need to be addressed and considered with regards to your site and wall location. We have found Redi-Rock installs easier, faster, and just plain better than any other retaining wall system on the market.

Build Higher Gravity Walls with Less Land Disruption

  • Because Redi-Rock is bigger and heavier than small block systems, it is more stable and can be built higher before requiring geo-grid or tie-back systems.
  • Because Redi-Rock gravity walls can be built higher, less land disruption is required.
  • The blocks are bigger than normal but with a piece of equipment, the blocks actually build faster than most smaller systems occupying more space faster and easier. Each Redi-Rock block occupies 5.75 sq. ft of space per facing block.
  • Because a machine does most of the work, usually only a small crew of 1-2 is needed depending on the job site saving you labor and time.

Typical Installation Overview

A high-level overview of the basic installation process for Redi-Rock retaining wall systems

  1. Site preparation and location
  2. Ground Preparation to Create a Leveling Pad Placement
  3. Backfill Leveling Pad
  4. Excavate to the lines and grades on the construction drawing
  5. Install block units. Position blocks to be offset from seams of blocks below. Blocks shall be placed fully forward so the knob and groove are engaged.
  6. Check each block for proper alignment and level. Backfill to 12-inch width behind the block with free-draining backfill.

Different site preparations and conditions can make installation more or less complicated. For more in-depth installation instructions, you will want to review the PDF Instruction Manuals available for download here.
