Retaining Wall FAQ

Answers to your retaining wall questions

In most Pittsburgh-area municipalities, walls under 4 feet do not require permits. However, walls over 4 feet typically need engineering approval and permits. We handle all permitting requirements and can advise on the best approach for your specific project.

The best choice depends on wall height, soil conditions, aesthetics, and budget. Segmental block walls are popular for their durability and appearance. Natural stone offers a classic look. Timber walls work well for shorter heights. We assess your site and recommend the optimal solution.

A properly built retaining wall should last 50-100 years. Concrete block and natural stone walls are the most durable. Timber walls typically last 15-25 years. Proper drainage behind the wall is crucial for longevity—we install drainage systems with every wall.

Yes, drainage is critical. Water pressure behind a wall is the leading cause of failure. We install gravel backfill and perforated drain pipes behind every retaining wall to direct water away and prevent hydrostatic pressure buildup.

Costs vary based on materials, height, length, and site conditions. Basic timber walls start around $15-25 per square face foot. Segmental block walls run $25-45 per square foot. Natural stone can range from $35-60+ per square foot. We provide free detailed estimates.

Often, yes. Repair options include installing additional drainage, reinforcing with tiebacks or anchors, or partial rebuilding. In some cases, complete replacement is more cost-effective. We assess the cause of failure and recommend the best solution.
