Retaining Wall Blocks

Retaining wall blocks make it easy to build strong, attractive garden walls that control erosion, create raised beds, and carve out level patios and pathways. These interlocking landscaping blocks are engineered for stability, so DIYers and pros can stack consistent courses, lock in setbacks, and finish with clean capstones. The result is long-lasting curb appeal and usable yard space with less maintenance than timber or loose rock.

Choose from concrete retaining wall blocks, split-face textures, natural stone looks, and large-format segmental retaining wall (SRW) units for taller structures. Many systems use integral lips or pins for alignment, with hollow cores that backfill and drain well. Corner units, radius blocks, and matching caps let you turn corners, build steps, and complete seating walls. UV-stable pigments and durable aggregates resist fading, chipping, freeze–thaw, and de-icing salts.

For a lasting DIY retaining wall, plan for proper base prep and drainage. Excavate to undisturbed soil, add compacted crushed stone, and set the first course level. Use drain tile, perforated pipe, and clean aggregate with landscape fabric to move water away. For taller walls, follow manufacturer specs for geogrid reinforcement and local codes. Helpful tools include a plate compactor or hand tamper, string line, torpedo level, masonry saw or chisel, rubber mallet, shovel, and safety glasses. Masonry adhesive bonds capstones and step treads.
