If you want to build a wall, you may have to sacrifice certain elements to keep costs down to what you can afford, otherwise your wall may have to wait. Keep in mind that sometimes you can combine the following materials to create unique and strong walls, such as when you may need extra support in one area and reinforcement with concrete or steel when using stacked blocks or stones elsewhere.

Make sure you don’t build higher than 4 feet from the ground, as higher walls require extra support and the need for a civil engineer to survey the area. Be sure to consider installing the first row of blocks below ground level when measuring the desired wall height. Use cloth behind boulders on sandy/gravel soils Do not use cloth on clay/loamy soils as cloth will clog, swell and push wall forward Always place larger boulders at the bottom Set tracks (rows) back 3 inches per foot of wall height Space out rows in a checkerboard pattern so that the seams do not match. Spend time joining the walls for a tighter fit. Extinguish the face of the boulders.

The second wall requires stronger materials, such as large retaining wall blocks, and may require revision of the design plans by the structural engineer. Both walls are 100 square feet, the first wall is so low that almost any type of material can be used, even ordinary pressure treated wood. Heavier walls are more resistant to erosion, freeze/thaw cycles, etc. Walls over 8 feet (sometimes even over 4 feet) require design (i.e. they are needed in order for the structure to be built correctly.

If you are creating an earthen wall, you should use one type of infill, which typically costs $20 to $25 per square foot. As with other building materials such as flooring or roofing, square meters are a convenient way to compare the cost of different types of retaining wall materials.
