Concrete block systems like Allan Block or Versa-Lok are ideal for taller walls and offer excellent structural integrity. Timber walls are budget-friendly for shorter applications. We assess your specific site conditions during our free consultation and recommend the best solution.

Most residential retaining wall projects take 2-5 days to complete, depending on wall length, height, and site conditions.

Retaining wall failures are typically caused by poor drainage, inadequate foundation preparation, or improper construction techniques. Water pressure behind the wall is the most common culprit. Proper installation includes a compacted aggregate base, drainage stone behind the wall, filter fabric, and often a French drain at the base. We follow industry best practices to ensure your wall lasts for decades.
