What to expect with retaining walls in Ko Olina
Retaining walls in Ko Olina need engineered drainage behind them and the right geogrid reinforcement above 3-4 feet of height. Without proper backfill drainage, hydrostatic pressure from Oahu rain events will push a wall out within a few wet seasons regardless of how solid the face looks. The crews we refer build in perforated pipe and gravel backfill as standard practice, not an upsell. On steeper Ko Olina hillside lots, structural engineer drawings may be required and our pros will tell you upfront whether your job falls in that category. Block, natural stone, and poured concrete walls each suit different site conditions and aesthetic goals, and the right choice usually comes down to what the soil and slope actually call for.
