Check the level of each block using a small level, front to back and side to side. Use a rubber mallet to tap each block in place. Make sure that the blocks are level with each other on all sides, front to back and side to side. The blocks should be laid with their edges touching. Lay the first row of blocks on the base material. Obviously, this will not work when building a curved wall. This will provide a guide to help ensure the wall is straight. When building a straight wall, establish a string line along the back side of where the first layer of blocks will be placed. This layer is used for bedding the first row of wall blocks.

Lay a 4- to 6-inch layer of the crushed base material in the trench. Round rocks, such as pea gravel, roll and dislodge under pressure resulting in failure of the retaining wall. The various-sized crushed gravel with the fines helps ensure the right amount of compaction. The base material should only consist of angular, sharp-edged particles such as ¾-inch minus gravel. Make sure that your trench is level and compacted. This provides strength and stability to your retaining wall. They should be buried about 1 inch deep for every 8 inches of wall height. Dig a trench for the bottom row of blocks. Preparing the base where the first layer of block will be placed is critical to building a well-placed, stable retaining wall. When installing a curved retaining wall, use a garden hose and spray paint to mark and map out the curved radius. Map out and measure your layout using stakes and string pulled tightly. The size of your wall depends on the size and shape of the space you have. You may need to consult an experienced installer, particularly if your retaining wall is over 4 feet high. Plan your project for the site where the retaining wall will go.
