Kiefer Landscaping has made it name by installing these retaining wall system to the exact engineered specification designed for each product for each specific project. In building a retaining wall the first step is deciding on the correct elevation for the wall to end up at, than you will know at what exact point the top of your base needs to be at. The next and most important step is getting a solid base. Varying on the height of the wall you have different depths for your compacted CA6 gravel base. When properly installing a base you should compact the CA6 in 2” to 3” increments to ensure proper compaction and to eliminate any settling. After you get your base block leveled in all directions on the CA6 base you simply need to stack the additional courses making sure to stagger the seams while backfilling the wall with CA7 gravel to a varying depth from the front of the wall that is based on the height of the particular wall. In most cases you will also need to provide some drainage near the base of the wall in the CA7 backfill. You do this by installing a 4” corrugated pipe that is slotted to allow water to access the pipe and run it out away from the wall. As you get to your desired elevation you will need to install block caps on some retaining wall systems, making sure to cut the caps to where there are no visible seams showing. For any retaining wall systems over 4’ tall you must install geogrid reinforcement material, on how many layers and how much length of the geogrid is also determined by the height of the wall, (it is often installed every 2-3 courses and approximately 4’-5’ back from the front of the wall).
