How long does a granite retaining wall last?

Granite retaining walls last 75–100+ years. Granite is one of the hardest natural stones available — it resists weathering, frost, and moisture far better than manufactured alternatives.

Is granite more expensive than concrete block?

Granite walls typically cost more upfront than concrete block, but require far less maintenance and last significantly longer, making them more cost-effective over the wall's lifetime.

Can granite walls be built on sloped ground?

Yes. Our crews are experienced at stepped and battered granite wall construction on sloped terrain. We assess soil conditions and plan the foundation to suit your site.

What does a retaining wall design service include?

Our design service covers structural engineering consultation, load-bearing assessment, soil pressure analysis, 2D drafting, 3D rendering, site plan integration, and permit application coordination.

How long does retaining wall design take?

Design timelines depend on project complexity. Simple residential wall designs can be completed in 1–2 weeks. Projects requiring geotechnical reports or council applications may take 4–8 weeks.

Can you design retaining walls for sloped sites?

Yes — we specialise in retaining wall design for sloped and challenging sites across the Twin Cities. We assess soil pressure, hydrostatic pressure, and foundation depth requirements for each site.
