Utilising a segmented wall system is a cost-effective and relatively easy way to build a decorative concrete wall. The blocks used with these systems are crafted from concrete in a variety of designs, colours and textures. No mortar is required to bond the blocks together, as they rely on internal latching devices to secure them to one another. Segmental decorative concrete blocks can be used to create boundary walls around your property or for other landscaping projects.

- Vibrating place compactor
- Segmental concrete blocks
Verify the wall layout on your property. Dig a trench 6 inches deep along the line of the wall. The width of the trench should be the width of the wall, plus 6 inches on each side.
Add 6 inches of 3/4-inch granular stone to the bottom of the trench. Use a vibrating plate compactor, available from equipment rental facilities, to compact the rock, being careful to follow the manufacturer's directions. Continue adding and compacting the rock until the compacted rock measures 6 inches in depth.
Lay the first course of decorative concrete blocks along the centre of the trench, keeping them in a straight line. Make sure that the blocks are level across the top and up the back of the block.
Place the second layer of decorative concrete blocks on top of the first in a staggered pattern, aligning the centre of each upper block with the connecting joints of the lower blocks. Pull each block forward until the connecting device is secure and attached to the lower blocks.
Continue stacking the decorative concrete blocks in this manner until the wall is the desired height. Different manufacturers may have different maximum heights for their decorative concrete blocks, ranging from 2 to 6 vertical feet, so check this specification before beginning your project.
