Residential Retaining Wall
Project Overview
When Despard Contracting was contacted for this residential retaining wall rebuild on Mayo Road, the existing structure had begun to fail—leaning outward and showing visible signs of erosion. The wall’s original drainage system was insufficient, allowing groundwater pressure to build up behind it over time. This combination of poor drainage and weather exposure made a full reconstruction the best long-term solution.
Excavation and Foundation
Our crew began by carefully dismantling the existing wall and excavating to reach a solid, stable base. A robust footing was then established to provide the proper foundation for the new residential retaining wall system. This step is critical, as the strength of any retaining wall depends on a properly compacted and leveled base that can handle both static and dynamic soil loads.
Drainage and Structural Design
Next came the installation of a new perimeter drainage system. We incorporated perforated drainpipe wrapped in filter fabric, layered with clean drain rock to ensure effective water flow away from the structure. This modern drainage design helps reduce hydrostatic pressure, preventing water buildup and minimizing long-term maintenance. With the foundation and drainage secured, our team constructed the new residential retaining wall using engineered block units selected for their strength, durability, and cohesive aesthetic.
Finishing and Integration
Every block was placed with precision to achieve tight alignment, proper backfill, and consistent reinforcement throughout the wall’s full length. During the process, we integrated the wall seamlessly into the property’s surrounding landscape—ensuring it complemented the home’s design and existing grade lines. The finished result is not only a structurally sound retaining wall but also a visually appealing landscape feature that enhances the overall property value.
Long-Term Performance
In addition to wall reconstruction, our crew managed site grading and soil stabilization, helping redirect runoff and protect the newly built structure. These details ensure the wall performs effectively through every season. The completed residential retaining wall now provides lasting support to the upper slope, protecting the foundation of the home and creating a secure, low-maintenance outdoor space.
