Local structural engineering firm for mountain construction. 

IONCON is a structural engineering firm built on decades of hands-on experience designing in the mountain environments of Western North Carolina. We understand the realities others miss—steep slopes, complex soils, snow loads, wind exposure, water management, and local permitting nuances that can make or break a construction project. From custom homes to commercial structures, IONCON brings practical, site-specific solutions that keep projects moving and budgets intact. If your project is in the mountains, call an engineer who’s been solving these challenges for years—not learning them on your dime. IONCON’s long-standing presence in the region means we understand what works—and what doesn’t—when it comes to mountain construction.

Structural
Analysis

IONCON can provide a structural assessment of cracked foundations, structural beams, differential settlement, retaining walls and un-level floors or decks to determine if the damage is significant to warrant repair. This type of engineering assessment can be done when buying or selling a property, during construction or renovation, or whenever structural concerns arise. Clients can choose a verbal report provided at an hourly rate, or a written report provided for a flat fee.

Retaining Walls

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 retaining 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
  • RETAINING WALL REMEDIATION
  • RETAINING WALL DESIGN

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. 

Decks

IONCON’s long-standing presence in the region means we understand what works—and what doesn’t—when it comes to mountain deck construction. If you’re planning a new deck, dealing with an inspection issue, or concerned about the safety of an existing structure, working with a local structural engineering firm makes all the difference. 

  • DECK STRUCTURAL INSPECTIONS
  • DECK REPAIR, REBUILD, RENOVATION​
  • MULTI-LEVEL NEW DECK DESIGN

Decks in the mountains of Western North Carolina face challenges that don’t exist in flatter regions. Steep slopes, changing soil conditions, high moisture, and freeze–thaw cycles all place unique stresses on deck structures. At IONCON, we provide structural engineering services for decks specifically designed for the terrain, climate, and building requirements of the Blue Ridge Mountains. With decades of experience working in Western North Carolina, our team helps homeowners, builders, and real estate professionals ensure decks are safe, code-compliant, and built to last.

From Our Clients

“If there’s one thing that I can say about IONCON, it’s that they put their customer’s best interests first. I worked for a foundation repair company that advised customers to have Patrick come out and advise them on their foundation issues. He always approached the job with their best interests at heart, and with their wallet in mind. I wouldn’t call anyone else in the high country with my engineering needs but IONCON. No doubt.”
