Contractors
Landscaping contractors like Versa-Lok retaining wall blocks because they make installing great-looking walls easy and cost-efficient. Versa-Lok blocks are a match for just about any retaining wall or hardscaping feature, and walls are made of high-strength concrete blocks, dry-stacked, interlocked with pins and set on granular leveling pads. These mortarless walls do not need frost footings. Versa-Lok walls easily accommodate soil reinforcement with geogrid, a cost-effective method for stabilizing soil behind tall walls.

The following information will provide you with a general understanding of retaining wall construction. For in-depth installation information, visit the Versa-Lok website.
Step 1 – Leveling Pad Preparation
Excavate and compact a 24-inch wide trench deep enough to accommodate a 6-inch crushed-rock leveling pad, 1/2-inch layer of sand and the embedded below-grade courses. The first course of Versa-Lok units should be embedded below grade at a minimum of 1/10 of the exposed wall height.
Step 2 – Install Base Course
Place Versa-Lok units on the compacted leveling pad. As you proceed, level each unit front to back, side to side and with adjacent units. Leveling is crucial at this stage, so take your time! Use a stringline stretched behind the wall to ensure straight alignment. If your wall has a corner, begin at the corner and work out from there.
Step 3 – Backfill Base Course
Replace and compact native soil behind and in front of the base course, level with the grade in front of the wall.
Step 4 – Install Successive Courses
Stack one course at a time, setting units 3/4″ back from the front of the wall. Overlap adjacent lower-course units by at least 4 inches to enhance structural stability, and keep all vertical face joints tight. Insert two pins in the front holes of the units so they fall into the rear slots of the units beneath, and tap them down with a pin and maller.
Step 5 – Install Drainage Aggregate & Backfill
Place and compact drainage aggregrate 12″ behind each course as it is completed, to a level of 12 inches below the top of the wall. Backfill and compact soil in any remaining open area behind the drain aggregrate. If required, install perforated drain pipe at base of drainage aggregate.
Step 6 – Install Caps & Finish Wall
Complete your wall by placing Versa-Lok cap units on the top course. Install caps with a slight overhang (recommended), set back and flush with the wall face. Secure cap units to the wall with concrete adhesive. Backfill the caps with topsoil after they are secured, complete your final grading and landscaping, and your Versa-Lok wall is now complete.

Functionality
How Versa-Lok Retaining Walls Work
In numerous situations, Versa-Lok segmental retaining walls function as unreinforced gravity structures, relying solely on the weight of the blocks to counteract earth pressures. The maximum permissible height for these gravity walls can fluctuate based on various factors, including soil characteristics and loading conditions. Typically, when backfill is level and there is no excessive loading present, unreinforced gravity walls made with Versa-Lok can be constructed up to a height of approximately four feet.
However, if the sheer weight of the units is inadequate to withstand soil loads, horizontal layers of Versa-Grid or alternative types of geogrid can be incorporated to provide additional reinforcement for the soil located behind the walls.
With appropriate soil reinforcement and expert design support from a licensed professional engineer, Versa-Lok retaining walls can reach impressive heights of 50 feet or even greater. This flexibility allows for a wide range of applications while ensuring structural integrity and safety.
