Welcome to the Infrastructure Repair LIVE podcast. On this podcast, you'll learn how to improve your marina docks, sheet piles, columns, piles, and mooring cells from QuakeWrap's CEO Prof Mo Ehsani, and Josh Ahumada. From repair projects to identifying and utilizing innovative solutions—you will understand what it takes to discover, manage, and successfully implement marine infrastructure repair and strengthening that drives long-term success. Through interviews, Q+A, and real-time projects we give you a sneak peek into the data-backed insights we are executing across the world.
Epoxy Fill vs. Cementitious Grout: Why Engineers Are Rethinking Timber Pile Repair with PileMedic
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 Pile Repair: The Benefits of PileMedic for Marine and Bridge Foundations
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

Innovations in Culvert Rehab: StifPipe for Circular Culverts (Part 2)
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.
