Installation of Retainig Walls-Planning and Preparation

Installation of Retainig Walls - Excavation

Step 1: Planning and Preparation Mark out the location of the wall. Before digging, call local utilities and cable to mark locations (this is usually a free service). Draw plan view showing measurements and grade elevations. The elevations are required to calculate how many retaining wall blocks are required. Go to a Unilock® Authorized Dealer who will calculate the amount of materials and estimate the cost.


Step 2: Excavation   a minimum of 6" - 12" deep is excavated depending on the size of wall unit you are using.   all loose soil removed. Remember that you need a minimum of 3" of gravel base and at least 3" of wall unit buried below grade level to help "toe in" the wall. You can save on materials if you step the wall up or down to accommodate the grade.

Step 3: Base  3" - 6" of gravel placed  in the trench and compacted using a hand tamper until very hard. In areas with more than 6" of gravel, we'll compact in 3" layers and leave enough room for the first row of wall units to be buried below grade level. The final height of the installation will determine the exact level that must be set.


Step 4: The levelling  Some wall styles come as "doubles" they are split first then the blocks individually  levelled using a mallet and a small level. We'll ensure that all blocks are levelled from side-to-side and front-to-back. After the first row is in, the rest of the units can be stacked, we off-set all vertical joints by starting with a block cut in half..

Step 5: Finishing  When placing our final row of blocks, (in some cases this might be a special cap called "coping"), we must glue them on with Unilock®'s Concrete Adhesive.  After gluing, we place in soil, put in sod, or install plants to complete your installation.
