Concrete Block Retaining Walls
Allan Block, Versa-Lok, and Belgard concrete retaining wall systems. Engineered for Wilmington's sandy, shifting coastal soil. Ideal for grade changes up to 6 feet.
Natural Stone Retaining Walls
Dry-stacked and mortared natural stone walls using granite, fieldstone, and boulders. Beautiful, permanent, and designed to complement your landscape for decades.
Timber Retaining Walls
Pressure-treated timber walls for low-to-moderate grade changes. Cost-effective solution for landscape beds, property borders, and gentle hillsides.
Drainage & French Drain Integration
Proper drainage behind a retaining wall is critical in Wilmington's high-rainfall, sandy-soil environment. We engineer drainage into every wall to prevent hydrostatic pressure and failure.
Culvert Pipe Installation
Corrugated metal and concrete culvert pipe installation for drainage control, driveway crossings, and water management. Sized correctly for your site's drainage load.
Erosion Control & Regrading
Yard grading, erosion control fabric, rip-rap placement, and site stabilization. We address the root cause of erosion before building any retaining structure.
What Wilmington Homeowners Say
“Had a serious drainage problem with water pooling against the house. Forest graded the yard, installed a retaining wall, and ran culvert pipe to redirect the flow. Problem completely solved. Excellent work.”
Ken W.

“Needed a retaining wall along my driveway that was eroding badly. Forest assessed the drainage first, built a solid block wall, and added French drain behind it. Two years later — no issues.”
Nancy P.

“Large natural stone retaining wall to create a flat area in our sloped backyard. The result is beautiful. Forest designed and built it in five days. Exactly what we envisioned.”

Retaining Wall FAQ — Wilmington, NC
How much does a retaining wall cost in Wilmington, NC?
Retaining wall costs in Wilmington run $15–$65 per square foot of wall face depending on material, height, and drainage requirements. A 50 linear ft concrete block wall at 3 ft height averages $6,000–$12,000. Taller walls with engineered drainage cost more. Free on-site estimates provided.
Do you install culvert pipes in Wilmington?
Yes. We install corrugated metal, concrete, and HDPE culvert pipes for driveway crossings, drainage control, and water management. We assess the required diameter and slope based on your site's drainage load.
What type of retaining wall is best for Wilmington's soil?
Concrete block systems (Allan Block, Versa-Lok) perform best in Wilmington's sandy coastal soil because they are engineered for drainage and can flex slightly without cracking. Natural stone is also excellent. Timber walls work well for low walls under 3 feet.
Do retaining walls need drainage in Wilmington?
Yes — always. Wilmington receives 50+ inches of rain per year, and hydrostatic pressure buildup behind a poorly-drained wall is the most common cause of retaining wall failure. We engineer drainage into every wall we build.
Do I need a permit for a retaining wall in Wilmington?
Retaining walls over 4 feet in height typically require a building permit in Wilmington and New Hanover County. We handle all permit applications for your project.
Can you fix a leaning or failing retaining wall?
Yes. We assess existing retaining walls for structural issues, drainage failures, and foundation problems. Depending on the condition, we can repair, rebuild, or replace the wall with a properly engineered system.
