Do I need a retaining wall on my property?
You might need a retaining wall if your yard has steep slopes, erosion problems, standing water, or uneven ground. Retaining walls protect your property from soil movement and help create level, usable outdoor spaces. We will evaluate your site, drainage, and soil conditions to recommend the right solution for your home.
What materials do you use to build retaining walls?
At GNG Underground, we use proven, durable materials including interlocking concrete block systems, natural stone, and reinforced poured in place walls. We will help you choose the right material based on the wall’s purpose, your budget, and the look you want for your property.
How long does a retaining wall last?
When properly designed and installed, a retaining wall can last decades. Most of our walls are built with engineered drainage systems and reinforced materials, which significantly extend their lifespan. Regular inspections and good maintenance can help your wall last 50 years or more.
What is included in your concrete driveway services?
We offer full service residential paving including driveway installation, resurfacing, grading, sealcoating, and repairs. From new construction driveways to replacement projects, we handle everything from excavation and base prep to drainage and final finish. You will get a smooth, durable surface that looks great and stands up to Arkansas weather.
How long does it take to complete a driveway paving project?
Do I need a permit for a retaining wall or driveway project in Northwest Arkansas?
In many cases, yes. Retaining walls over a certain height or those supporting structures may require engineered plans and a permit. Some municipalities also require permits to ensure proper drainage. GNG Underground assists with permit coordination and compliance for your city or county.
How do I keep my retaining wall and driveway in good condition?
Maintenance is simple but important. Keep drainage areas clear, inspect for settling or cracks, and avoid planting large trees near your wall. Our team can guide you on the right care plan for your property.
