This is a perfect time of year to build a retaining wall for your home landscaping. The temperatures a bit lower and the soil for the most part are dry and stable unlike the normal spring. Retaining walls are built in the landscaping for a number of reasons but the most common reason is to have more flat usable land. The first part of the project will be to figure out the height of the wall and the length of the wall. Homeowners should build walls no higher than three feet in height unless it is engineered. We now know how many wall blocks we need for the project, so it is time to pick out the wall block material. There are different colors and textured surfaces of the block to enhance the look you want. First dig a trench about 12” deep and pour in 4 to 6” of washed gravel into the trench. The gravel will provide a stable base for the wall.
Once the gravel has filled the space use a tamper to compress the gravel. Set the blocks along this gravel shelve and make sure it is level. About 6” of the block will be underground, using a level make sure the side to side and the front to back be level. Now place the block next to the one that was just set and make sure it is level to the existing block. Fill the inside of the block with gravel to add stability and strength and use the tamper again. The second course of block should rest comfortably on top of the first course. Each block should be place half way over the seam of the bottom block and again filled with gravel. When the wall is high enough a cap will set on top of the wall. Proper drainage from behind the wall will occur through the many seams between the blocks. This project is not difficult to do but is labor intensive.
