Retaining Wall Design & Installation

Why Retaining Walls Are More Than Decoration

Retaining walls do critical work holding back soil and preventing erosion on sloped properties. They create level areas for landscaping, patios, and outdoor living spaces. They protect your foundation from soil pressure and water runoff. A properly designed and built retaining wall can last 50 to 100 years. A poorly built wall can fail in just a few years, causing thousands of dollars in damage to your property.

We have seen too many failed retaining walls built by inexperienced contractors or ambitious homeowners. The wall looks fine when first completed, but within a few years it starts leaning, cracking, or bulging. The problem is usually inadequate drainage or improper foundation preparation. Water builds up behind the wall, creating pressure that pushes it over. Without proper footing and reinforcement, the wall cannot resist the forces acting on it.

Our retaining wall design and installation services are based on engineering principles and decades of experience. We assess your site conditions, soil type, drainage patterns, and the amount of soil the wall needs to retain. We design walls with proper drainage systems, adequate footings, and appropriate materials for your specific situation. Whether you need a small garden wall or a major structural retaining system, we build it right the first time. For homeowners seeking comprehensive exterior improvements, we also offer expert masonry services in Carlsbad for all your construction needs.

The Engineering Behind Lasting Retaining Walls

Building a retaining wall that lasts requires understanding the forces at work. Soil exerts tremendous lateral pressure, especially when saturated with water. Gravity pulls the wall forward and down. Freeze-thaw cycles create additional stress. A properly engineered wall resists all these forces through careful design and construction.

Foundation and Footing

Every retaining wall needs a solid foundation below the frost line. We excavate to stable soil and create a level base using compacted gravel. For walls over three feet tall, we typically pour a concrete footing to provide additional support and prevent settling. The footing width depends on wall height and soil conditions. Skipping this step or doing it incorrectly is the main cause of wall failure. We never take shortcuts with foundations because we know they determine how long your wall will last.

Drainage Systems

Proper drainage is absolutely critical for retaining wall longevity. We install perforated drain pipes behind the wall to collect water and direct it away from the structure. We use gravel backfill that allows water to flow freely to the drain pipe rather than building up pressure behind the wall. We ensure the drain pipe outlets are positioned to carry water far from the wall base. Many failed walls we repair had no drainage system at all or had pipes that were clogged or improperly installed.

Reinforcement and Geogrid

Tall retaining walls or walls holding steep slopes often require additional reinforcement. We use geogrid fabric layers anchored deep into the soil behind the wall. This distributes the load over a larger area and significantly increases wall stability. The geogrid essentially ties the wall to the soil mass behind it, creating a composite structure stronger than either element alone. For segmental block walls, we use mechanical connectors and pins to tie courses together.

Building Code Compliance

Carlsbad has specific building codes for retaining walls, especially those over four feet tall or supporting structures. We are familiar with local requirements and handle all necessary permits and inspections. Walls must meet engineering standards for your specific soil conditions and load requirements. We provide calculations and drawings when needed for permit approval. This protects you legally and ensures your wall is built to current safety standards. If you need expertise in other masonry areas, we also provide professional chimney repair and rebuilding services.
