JPM Construction Services builds retaining walls across Marietta, GA and surrounding Cobb County communities. Whether you’re stabilizing a slope, protecting a foundation, expanding a usable yard, or solving a drainage problem — we build walls that won’t bow, crack, or fail in five years.
Every wall we build includes a complete drainage system. We handle the engineering and permitting on walls over 4 feet. The same in-house crew is on your project from excavation through final cleanup.
Site evaluation done in person. Not over the phone, not from a satellite image. We walk the property and assess the actual conditions.
A written estimate, not a verbal quote.
Every line itemized. Footings, drainage, materials, reinforcement, labor. You see exactly what you’re paying for.
Engineering coordination for walls over 4 feet.
Required by Georgia state code. We handle the engineer, the plans, and the permit so you don’t have to.
A complete drainage system on every wall.
Gravel backfill, perforated drain pipe, weep holes, and surface grading. We don’t quote walls without it. It’s the difference between a wall that lasts 30 years and one that fails in 5.
Properly sized footings.
Sized to your specific wall load and soil conditions. Set below frost line on stable ground.
Steel reinforcement throughout.
Rebar placement that handles the lateral pressure your wall will face. Geogrid soil reinforcement on taller walls.
Backfill compacted in lifts.
Soil placed in 6 to 8 inch layers and compacted properly. Cutting corners here is why most failed walls fail.
A finished site.
Final grading directs water away from the wall. Worksite left clean.
Poured Concrete
The strongest, most permanent option. Ideal for taller walls and structural loads.
Segmental Block
Interlocking concrete block available in multiple colors and textures. Versatile for residential walls and terracing.
Concrete Block (CMU)
Cost-effective for shorter walls. Fully customizable with stucco, stone veneer, or paint.
We’ll recommend the right wall type during your estimate based on your site, height requirements, and budget.
Walls under 4 feet:
Typically complete in under a week
No permits required in most Cobb County jurisdictions
Walls over 4 feet:
2 to 3 weeks of construction once permits are issued
Engineering and permitting add 2 to 4 weeks before construction starts
Local Knowledge
Years of experience working in Marietta soil, slopes, and Cobb County code requirements.
Drainage on Every Wall
We don’t build walls without proper drainage. It’s the number one reason walls fail in this region, and we won’t quote a wall without it.
In-House Crew
Same team start to finish. Consistent quality, reliable scheduling, one point of contact.
Engineering Handled For You
For walls over 4 feet, we manage the engineer and the permit. You don’t deal with either.
Upfront Pricing
Written estimates with every line item spelled out. No hidden costs, no surprise change orders.
JPM Construction Services builds retaining walls throughout Marietta, Alpharetta, Dallas, Kennesaw, Douglasville, Smyrna, Roswell, Acworth, and Powder Springs.

Retaining walls are priced per linear foot, with cost depending on height, material, drainage requirements, and whether engineering is required. Walls under 4 feet typically cost less per foot than engineered walls over 4 feet because they don’t require formal engineering plans or permitting. Material choice matters too: concrete block walls are generally the most affordable, segmental block falls in the middle, and poured concrete is the most expensive but longest-lasting. Every project gets a detailed written estimate.
Walls under 4 feet measured from the bottom of the footing to the top of the wall typically don’t require permits in Cobb County. Walls over 4 feet require engineering plans and permits per Georgia state code. The permit process exists because taller walls handle significantly more lateral pressure and need engineered design to prevent failure. We handle all engineering coordination and permitting as part of the project.
A properly built wall with adequate drainage lasts 30 to 50 years or more. The single biggest factor in retaining wall lifespan is drainage. Walls built without proper drainage systems often fail within 5 to 10 years because hydrostatic pressure builds up behind the wall as Georgia red clay holds water. Every wall we build includes gravel backfill, perforated drain pipe at the base, weep holes through the wall face, and proper surface grading.
The right wall type depends on height, soil conditions, drainage needs, aesthetic goals, and budget. Poured concrete is the strongest and most permanent option, typically used for walls over 6 feet or walls supporting structural loads like driveways. Segmental block walls are versatile and visually softer, ideal for most residential applications under 8 feet. Concrete block (CMU) walls are cost-effective for shorter walls and can be finished with stucco, stone veneer, or paint to match home exteriors. We’ll recommend the right type during the estimate.
Walls under 4 feet typically complete in under a week from start to finish. Engineered walls over 4 feet require 2 to 3 weeks of construction once permits are issued. Engineering review and permit processing add 2 to 4 weeks before construction can start, so the full timeline for a permitted wall is typically 4 to 7 weeks from estimate signing to project completion.
In most cases no, repair isn’t the right call. When a wall is bowing, cracking, or leaning, the underlying issues are usually drainage failure, footing problems, or inadequate reinforcement, none of which can be fixed without rebuilding. Patching visible damage might buy a year or two but leaves the underlying problems in place. We’ll evaluate your situation during the estimate and recommend the most cost-effective option, which is usually rebuild with proper drainage.
Most retaining wall failures in the Marietta area come down to drainage, not the wall itself. Georgia red clay soil holds water, which creates hydrostatic pressure against the back of the wall. Without a proper drainage system to relieve that pressure, the wall eventually bows, cracks, or fails entirely. A well-built wall with proper drainage handles this pressure for decades. A wall built without drainage rarely lasts more than 10 years regardless of how solid it looks when finished.
JPM Construction Services builds retaining walls that don’t fail. Properly engineered, properly drained, properly built. Whether you’re stabilizing a slope, protecting your foundation, or making a sloped lot usable, we’ll show up on time, build it right, and stand behind the work.
