FAQs
Everything you need to know.
- How high can an interlocking retaining wall be built?
- Standard interlocking walls typically reach 3–4 feet without engineering. Taller walls require geogrid reinforcement and engineering approval, which we handle as part of our service.
- Do interlocking retaining walls need drainage?
- Yes — proper drainage is essential. We install perforated drain pipe and clear gravel aggregate behind all walls to prevent hydrostatic pressure and ensure long-term stability.
- What is interlocking retaining wall block?
- Interlocking blocks are precast concrete units that stack and connect with built-in pins or lips — no mortar required. The gravity-based system creates strong, flexible walls that move slightly with frost without cracking.
- How long do interlocking retaining walls last?
- Quality interlocking retaining walls can last 50+ years with proper installation and drainage. The concrete blocks resist weathering and freeze-thaw cycles extremely well.
