Your Local Retaining Wall Experts 

A retaining wall is a structural masonry or block wall built to hold back soil, prevent erosion, and create level, usable space on sloped properties. D. Thomas Masonry, Inc. designs and builds retaining walls across Erie County (PA), Crawford County (PA), and Chautauqua County (NY), using segmental block, natural stone, and structural block systems for driveway edges, hillside stabilization, tiered gardens, and terraced yards. Founded in Erie, PA in 2006, the team brings more than 80 years of combined masonry experience to each build, with careful attention to drainage, base preparation, and long-term structural performance.

Our Retaining Wall Solutions 

  • New Retaining Wall Installation

    Whether you want to create level planting beds in your garden, support a driveway on a slope, or define the edge of a patio, we’ll recommend the best materials and construction methods for your project.

    Our team handles everything from site preparation and excavation to the final finishing touches, so you can trust that your new wall is both structurally sound and visually appealing.

  • Retaining Wall Repairs

    If your existing retaining wall is showing signs of distress (such as leaning, cracking, bulging, or separating), we can help! Our experienced masons (jump to history on homepage) will thoroughly assess the underlying cause of the problem, whether it’s poor drainage, shifting soil, or aging materials.

    We then implement targeted repairs, which may include rebuilding sections, reinforcing the structure, or replacing damaged blocks or stones.

  • Integrated Drainage Systems

    Without proper water management, even the best-built retaining wall can fail over time. That’s why we incorporate effective drainage solutions into every project, such as gravel backfill, perforated drain pipes (French drains), and weep holes.

    These features help direct water away from the wall while preventing soil erosion, ensuring your wall remains secure and maintenance-free for years to come.

  • Landscape Coordination

    A retaining wall should do more than provide support; it should elevate the look and feel of your entire outdoor space. At D. Thomas Masonry, we collaborate with you to choose materials, colors, and finishes that harmonize with your home and existing landscape features.

    Looking to add something special? We can smoothly blend your new wall with garden beds, walkways, steps, or patios to create an inviting setting. Custom features like built-in planters and seating may also be added!
