Infrastructure Repair LIVE

Engineers across the U.S. are increasingly specifying epoxy fill over traditional cementitious grout for timber pile repair. In this episode of Infrastructure Repair Live, Professor Mo Ehsani is joined by field engineers Lex and Josh for a live panel and demonstration — breaking down the engineering behind the shift and showing why PileMedic's FRP confinement system paired with epoxy fill is emerging as the superior approach for restoring deteriorated timber piles.

What we'll cover:

• Why epoxy penetrates where grout can't. Low-viscosity epoxy gravity-feeds into borer channels, checks, and decay voids in deteriorated wood — consolidating the remaining timber cross-section into a structural composite.
• The confinement advantage. PileMedic's seamless FRP shell applies 360-degree uniform hoop stress with no longitudinal seams — eliminating the moisture and oxygen pathways that defeat conventional fiberglass pile jackets.
• Epoxy grout vs. neat resin — when to use which. A two-component, low-viscosity structural epoxy designed to saturate degraded wood zones, versus a three-component system with aggregate filler — engineered for larger annular cavities.
• No shrinkage, no porosity, no recontamination. Cured epoxy is non-porous and dimensionally stable.
• Whether you're specifying your first epoxy-filled pile repair or evaluating it against cementitious alternatives you've used for years, this session gives you the technical detail to make an informed decision.

Timber piles are still supporting critical infrastructure across the U.S., from waterfront structures and marinas to bridge foundations that may not be fully submerged. In many regions, deterioration is accelerating due to increased biological activity and infestation, creating higher repair urgency and tighter constraints on installation time and budget.In this episode of Infrastructure Repair Live, Mo Ehsani and Josh Ahumada will walk through a field-focused breakdown of timber pile repair using PileMedic, including:

How confinement supports structural repair for deteriorated timber piles

Why controlling the annular space matters for predictable installation and performance

How fill material selection impacts swelling risk and long-term durability

Where epoxy grout can make sense, and how economics can shift when the annulus is controlled

How timber-adjacent applications like utility poles reflect similar repair principles

In Part 2 of our culvert rehabilitation podcast series, we are breaking down one of the most innovative FRP technologies in our industry: StifPipe®, QuakeWrap’s patented CFRP honeycomb liner for deteriorated corrugated metal pipe (CMP) culverts.
Originally developed from decades of aerospace R&D, StifPipe’s honeycomb core acts like the web of an I-beam, while the inner and outer FRP skins act like the flanges, delivering exceptional stiffness and strength without stacking 10+ layers of carbon fabric. The result is a lightweight, corrosion-proof, stand-alone structural liner that restores the culvert’s load-carrying capacity under soil and traffic loads.
In this episode, Mo will walk through:
How StifPipe is designed and manufactured using aerospace-inspired honeycomb technology
Why this liner resists internal pressure, external soil loads, corrosion, and traffic loads
How StifPipe can be built to virtually any size or shape, including non-circular culverts
Field installation advantages: lightweight sections, easy assembly, and minimal equipment
Real-world case studies like the Arc Terminal project in Alabama and a custom rough-surface liner developed for Hong Kong
If you're dealing with aging CMPs or complex culvert geometries, this episode shows why StifPipe is becoming a go-to solution for DOTs and public works teams worldwide.

In this two-part series of Infrastructure Repair Live, we explore advanced, proven methods for rehabilitating deteriorating culverts without costly replacement.

Part 1 covers Wet Layup FRP and SPiRe+ for box culverts - a versatile trenchless repair method that restores strength, prevents corrosion, and minimizes traffic disruption. We’ll walk through:

• How wet layup works in the field

• Its advantages over traditional methods (lightweight, corrosion-resistant, minimal traffic disruption)

• Real-world applications where it has saved owners time and money
  

Part 2 will spotlight StifPipe®, QuakeWrap’s patented CFRP honeycomb liner for corrugated metal pipe culverts. StifPipe® was born out of decades of aerospace R&D, using a honeycomb core to deliver stiffness without stacking 10+ layers of carbon fabric. The result: a stand-alone liner that resists internal pressure, external soil loads, and traffic loads, all while reducing material cost and installation time.

Whether you’re a bridge engineer, DOT official, asset manager, public works leader, or consultant,  this series will give you proven, cost-effective strategies to rehabilitate culverts and pipelines without full replacement OR impact to the flow capacity.

In this special episode of Marine Infrastructure Live, we'll take an in-depth look at QuakeWrap's latest innovations. We'll share exclusive insights into the company's ongoing research and development, with a focus on the rigorous testing of their SPiRe+ panel system.

Listeners will get a behind-the-scenes look as our team performs tests on both the 3-inch thick SPiRe+ panel, which is the most commonly used for marine infrastructure repair, as well as a new 2-inch thick panel that shows promise for innovative applications like fire-resistant roofing for industrial and commercial buildings.

We'll walk you through the testing process and demonstrate the performance of these advanced composite materials under load. This episode will give our audience a deeper understanding of the engineering considerations and innovative approaches that go into developing QuakeWrap's cutting-edge solutions.

In this episode, we'll take an in-depth look at QuakeWrap's work on a critical slab repair project for a beloved oceanfront resort in Pine Knoll Shores, North Carolina. Nestled along the picturesque Crystal Coast, this historic lodge was damaged due to the harsh coastal environment, with corrosion compromising the integrity of its pre-stressed concrete hollow-core slabs.
Listeners will learn how QuakeWrap's innovative SPiRe+ system was leveraged to address this challenge, providing a durable, long-lasting solution that not only restored the structural integrity of the building but also safeguarded it against future deterioration. We'll explore the unique engineering considerations and construction techniques employed to overcome the obstacles posed by the seaside location, including the use of stay-in-place forms, strategic reinforcement, and protective measures against saltwater intrusion.
We'll also discuss QuakeWrap's work on a slab repair project for an industrial facility in St. Paul, Minnesota. By drawing these parallels, we'll demonstrate the widespread applicability of QuakeWrap's expertise in addressing concrete slab challenges, regardless of a building's location or industry. Listeners will come away with a deeper understanding of the innovative solutions QuakeWrap provides for repairing and protecting corroded slabs, ensuring the longevity and safety of structures in diverse environments.

In this episode of Marine Infrastructure Live, Mo Ehsani returns with an insightful discussion on one of the most underutilized yet impactful use cases of QuakeWrap’s PileMedic® system: single-layer FRP jackets used for pile protection.

Not every pile reinforcement project demands major structural upgrades. In many cases, engineers and facility managers are simply looking for a fast, reliable way to protect existing piles from future deterioration—without costly, disruptive welding or full-strengthening retrofits. That’s where the power of PileMedic® as a protective jacket shines.

In this episode, you’ll learn:

• When and why to use single-layer FRP jackets for corrosion protection

• How the installation process differs from load-bearing designs

• What to consider when designing these jackets for longevity and environmental durability

• Real-world examples of pile protection

• How a half-inch annular space filled with epoxy grout can make all the difference
  

This conversation is ideal for engineers, contractors, facility managers, and anyone working on infrastructure in corrosive marine or industrial environments.
