Residential Retaining Wall

This residential retaining wall project on Mayo Road showcases the strength, precision, and craftsmanship that Despard Contracting brings to every site. The homeowners needed a long-term solution to stabilize the steep slope behind their house and improve the property’s drainage. Our team rebuilt and reinforced the existing wall system from the ground up, integrating modern materials and proper water management to ensure structural integrity and a clean, finished look that enhances both safety and appearance.

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.
