Retaining wall blocks can be a smart investment. They can add aesthetic value to your property and protect your landscaping from soil erosion that can pollute water sources, disturb gardens and cause basement leaks.

lightweight retaining wall blocks are a great alternative to heavier masonry materials. They are less expensive to purchase and install, making them a good choice for homeowners on a budget.

Blocks are available in a variety of sizes and styles. Some come in tumbled, weathered appearances that resemble natural stone and other types feature beveled sides that allow you to create graceful curves.

Begin by preparing the area for the retaining wall. Lay down a base layer of gravel in the trench to ensure a solid foundation. Use a shovel to backfill in small portions, tamping the gravel down as you go.

Next, lay out your first course of retaining wall blocks. Position each block so it is centered over a joint in the bottom base course, and make sure that its rear lip touches the blocks beneath. This pattern is called “running bond.”

Once you’ve laid out your first course of blocks, continue laying more courses until the wall reaches its desired height. Once it reaches the top, add capping blocks to finish the wall.

Concrete blocks can be a good choice for a budget-friendly retaining wall, but they don’t have the same wide range of colors and design options as stone or brick. They are lightweight and easy to handle, but they aren’t strong enough to support tall retaining walls without reinforcements.
