Modular retaining wall FAQs
Are modular walls as strong as limestone?
Yes, for typical residential walls. Strength comes from proper footing, drainage, and interlocking blocks. Taller walls are reinforced with geogrid for added stability.
How high can a modular wall go?
Modular walls can be built to various heights. Taller walls may require council approval and engineering. We check requirements before quoting.
Do the colours fade?
The colour runs through the block rather than sitting on the surface, so it holds up well in the Perth sun. Expect it to soften slightly in the first year and then stay put.
