Retaining walls in the mountains of Western North Carolina face unique structural challenges. Steep slopes, clay-heavy soils, freeze–thaw cycles, and heavy rainfall all increase the risk of wall movement and failure. IONCON provides professional retaining wall assessment, remediation design, and new retaining wall engineering for residential and commercial properties throughout Western North Carolina. Whether your wall is showing signs of distress or you’re planning new construction on a sloped site, we deliver engineer-led solutions focused on safety, longevity, code compliance, and affordability.

​

Retaining Wall Assessment & Inspection

A failing retaining wall is more than a cosmetic issue — it can pose serious risks to people, structures, and property value. IONCON can perform comprehensive retaining wall inspections to evaluate structural stability, drainage performance, soil conditions, and failure risk.

 

Common signs your retaining wall may need an assessment:

• Leaning or bulging walls

• Cracks in concrete, masonry, or stone

• Separation between wall sections

• Rotting timber walls

• Soil erosion or sinkholes near the wall

• Standing water or poor drainage behind the wall

 

Retaining wall assessments are especially valuable for:

• Mountain homes on steep lots

• Older timber, stone, or dry-stack retaining walls

• HOA and shared retaining wall systems

• Real estate transactions and due diligence

 

Deliverables include:

• On-site structural evaluation

• Identification of failure mechanisms

• Risk assessment and urgency recommendations

• Engineering opinions and next steps

• Written reports with engineer's stamp

 

 

Retaining Wall Repair & Remediation Design

When a retaining wall is compromised, proper remediation starts with engineering — not guesswork. IONCON designs repair and stabilization solutions tailored to Western North Carolina terrain and soil conditions. Our role is to determine why the wall is failing and provide a repair strategy that addresses the root cause.

 

Remediation design services may include:

• Structural repair recommendations

• Drainage improvements and water management

• Tiebacks, anchors, or reinforcement systems

• Partial or full wall replacement strategies

• Coordination with contractors and builders

 

IONCON's stamped engineering designs help ensure repairs are:

• Structurally sound

• Cost-effective

• Built to perform long-term in mountain conditions

• North Carolina Building Code compliant

​

 

New Retaining Wall Engineering & Design

If your property is located on a slope, chances are your retaining wall requires specialized engineering attention. Building a new retaining wall in mountainous terrain requires careful consideration of slope stability, soil pressure, drainage, and loading conditions.

 

IONCON provides custom retaining wall design for:

• Residential hillside & mountainside properties

• Driveways and access roads

• Parking areas

• Terraced landscapes

• Commercial and multi-family developments

​

Types of retaining walls we commonly design:

• Reinforced concrete retaining walls

• Segmental block retaining walls

• Boulder retaining walls

​

Each retaining wall design is site-specific and considers:

• Local soil conditions

• Drainage and groundwater

• Surcharge loads

• Applicable building codes

 

 

Why Hire a Structural Engineer for Retaining Walls?

Retaining walls are structural systems, not landscaping features. Improper design or repair can lead to premature failure, increased costs, and liability exposure. In the State of North Carolina, if a retaining wall is more than 4 feet tall, it must be designed and/or approved by a licensed engineer.

​

Working with a licensed structural engineer ensures:

• Accurate evaluation of wall performance

• Solutions based on engineering analysis

• Compliance with local codes and regulations

• Reduced risk of repeat failures

​

This is especially important in Western North Carolina’s mountainous environment, where environmental forces place additional demands on retaining wall systems.
