Retaining Wall Blocks: Types, Costs, and Best Uses

Retaining wall blocks offer versatile, engineered solutions for walls of all sizes. Available in interlocking, standard, and split-face options.

Interlocking Blocks

Lip-and-groove systems that lock together without mortar — fast to install and naturally resistant to movement.

Cost

$250–$550/m² in Perth. Our block wall cost guide has detailed pricing. Use the cost calculator to estimate your project.

Block vs Sleeper

Blocks are better for curves; sleepers are faster for straight runs. Both are excellent choices for Perth conditions.
