Frequently asked
Retaining Walls in Nanaimo — FAQ
- How much does a retaining wall cost per square foot?
- Prices depend on material choice: concrete block runs $15–$40 per sq. ft. of wall face, timber runs $20–$25, poured concrete runs $20–$45, natural rock runs $45–$65, and engineered walls run $80–$88. You can review all material pricing options in our complete cost guide.
- How do I choose the right retaining wall material for my lot?
- We evaluate your slope height, property access, and aesthetic preferences during our site visit. Timber works well for low garden terraces, while concrete blocks handle medium heights efficiently. For heavy structural retention, poured concrete or stacked natural rock provides long-term strength.
- Why is drainage behind a retaining wall so important?
- Trapped water creates hydrostatic pressure that pushes against the back of the wall face. We place clear crushed rock and perforated drain pipe behind every wall to channel groundwater away safely. Proper drainage prevents soil saturation and protects your wall from leaning or cracking over time.
- Which communities do you serve on Vancouver Island?
- We build retaining walls across eight local communities from Duncan up to Qualicum Beach. Our work covers Nanaimo, Lantzville, Nanoose Bay, Gabriola Island, Parksville, Qualicum Beach, Ladysmith, and Duncan. You can view full details on our service areas page.
- How fast will I receive a reply after contacting you?
- We respond to every inquiry within 24 hours to answer your questions and arrange a site visit. You get a prompt response so you can plan your project timeline. Once we complete the site visit, we send your written quote right after.
- What site preparation is required before wall construction begins?
- We manage the excavation work, base digging, and soil removal needed for your new footing. You only need to ensure clear access for equipment to reach the work zone in your yard. We clear the footprint, level the trench, and install compacted gravel before setting materials.
