Retaining Wall
Mark off the area with a string line and allow for extra room on the sides of the retaining wall blocks for a good gravel base.
Estimate the materials needed, chose desired retaining wall blocks, the size you choose will determine the amount needed, for example: if 12 inch blocks are used the number times the linear foot needed is obvious. If 8 or 16 inch blocks are used, convert total linear distance needed to inches and divide by 8 for an eight inch block. Estimate base material -gravel(3/4 ” quarry process) for under retaining wall, use 4-6 inch gravel base, more if retaining wall is higher in size.
Preparing for a good retaining wall base is important and will be the most time consuming process. Grade the retaining wall base with a rake and 2X4 to get an even base where the wall will be placed. When installing string line, keep in mind that the first coarse of blocks should be 3/4 buried for good support of the entire wall.
measure block in place and cut on your marked line. (depends on type of block used) secure with a landscape block adhesive for added strength.
Finish the retaining wall by adding or back fill any more base material or black dirt in front or behind the wall, seed grass if needed. Tip: Use Landscape Block Adhesive between each coarse of blocks, run a bead of caulk across the blocks, this will make the wall stronger and moisture will not leak through the blocks, they will be sealed.
