Your Local Retaining Walls Experts in Sewell
Concrete retaining walls solve grading problems, prevent soil erosion, and create usable flat areas on sloped properties. Whether you need to hold back a hillside, create terraced landscaping, or protect a foundation from soil pressure, a properly engineered retaining wall is a long-term structural solution — not just a landscape feature.
Before You Start: Check your property survey before building — retaining walls near property lines may need neighbor notification or setback compliance. Underground utilities must be located before excavation. Consider how the wall will affect drainage patterns on your property and your neighbors'.
Why Choose Us
Retaining Walls Experts Serving Sewell
Erosion Control
Stop soil from washing away during heavy rains. Retaining walls with proper drainage hold slopes in place and protect landscaping, driveways, and structures below.
Usable Space Creation
Turn sloped, unusable yard areas into flat terraces for gardens, patios, or play areas. Retaining walls let you maximize your property's functional space.
Foundation Protection
Retaining walls redirect soil pressure and water flow away from home foundations, preventing moisture intrusion and structural damage from hydrostatic pressure.
Structural Longevity
Poured concrete retaining walls outlast block or timber alternatives. With proper drainage and reinforcement, they resist the constant soil pressure that degrades other materials over time.

How It Works
Our Retaining Walls Process in Sewell
Site & Soil Evaluation
We assess the slope, soil type, water drainage patterns, and the height of retention needed. Walls over 4 feet typically require engineering calculations for proper design.
Engineering & Permits
For walls over 4 feet, we coordinate structural engineering including reinforcement schedules, footing size, and drainage specifications. We handle all permit applications and inspections.
Footing & Drainage Installation
We excavate the footing trench below frost line, install drainage pipe and gravel behind the wall location, and pour the reinforced concrete footing that anchors the entire wall.
Wall Construction
We set forms, install rebar per engineering specs (vertical and horizontal), and pour the wall in sections. Proper vibration ensures the concrete fills all voids around reinforcement.
Backfill & Drainage Completion
After the wall cures, we install filter fabric and drainage gravel behind the wall, connect drain pipes to daylight outlets, and backfill in compacted lifts. Surface grading directs water to drainage points.

Common Questions
Retaining Walls FAQs for Sewell
How tall can a retaining wall be without engineering?
In most New Jersey municipalities, retaining walls up to 4 feet in exposed height can be built without engineered drawings. Walls over 4 feet require structural engineering, a building permit, and inspections. We recommend engineering for any wall over 3 feet to ensure proper design, especially on properties with clay soil or high water tables.
What causes retaining walls to fail?
The number one cause is poor drainage — water builds up behind the wall creating hydrostatic pressure that pushes it over. Other causes include inadequate footing size, insufficient reinforcement, building on unstable soil, and not accounting for surcharge loads (like a driveway or structure above the wall). Proper drainage is the single most important factor.
How much does a concrete retaining wall cost?
Poured concrete retaining walls typically cost $30 to $60 per square foot of wall face, depending on height, engineering requirements, and site conditions. A 3-foot tall, 30-foot long wall (90 sq ft face) runs $2,700 to $5,400. Walls requiring engineering add $1,000 to $2,500 for design. Taller walls cost proportionally more due to larger footings and heavier reinforcement.
Poured concrete vs block retaining walls — which is better?
Poured concrete is stronger, more watertight, and handles greater soil pressures than concrete block. Block walls are less expensive for short walls (under 3 feet) but can develop cracks at mortar joints. For walls over 3 feet or where water pressure is a concern, poured concrete is the better investment for long-term performance.
