Retaining Wall Installation FAQ for Hilo (Big Island) Homeowners

How often should Hilo (Big Island) homeowners get retaining wall installation?
Given Hilo (Big Island)'s hilo averages 130 inches of rain per year — one of the wettest us cities, most homeowners benefit from retaining wall installation at least once a year. Year-round mold and mildew management in Hilo's 130-inch rainfall zone often makes spring or fall the optimal time to schedule service.
What home types in Hilo (Big Island) most need retaining wall installation?
Plantation-style homes in Hilo and Puna districts and Off-grid homes in lower Puna — many built without permits historically are the most common home types in Hilo (Big Island) and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
Do retaining walls need drainage?
Yes — drainage behind retaining walls is critical. Without it, hydrostatic pressure from saturated soil and freeze-thaw cycles are the primary cause of wall failure. A gravel backfill zone and perforated drain pipe should be included.
What material makes the best retaining wall?
Segmental retaining wall block (like Allan Block) is the most popular — durable, easy to maintain, and comes in many styles. Natural stone is beautiful but more expensive. Timber is lowest cost but has a 15–20 year lifespan.
How tall can a retaining wall be without a permit?
Most jurisdictions allow walls up to 3–4 feet without a permit. Taller walls require engineering and permits to ensure structural safety.
Can I build a retaining wall myself?
Small walls under 3 feet using segmental block are manageable DIY projects. Taller walls — especially those retaining significant soil loads — require professional engineering and installation to prevent failure.
