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

<p>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.<br>Originally developed from decades of aerospace R&amp;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.<br>In this episode, Mo will walk through:<br>How StifPipe is designed and manufactured using aerospace-inspired honeycomb technology<br>Why this liner resists internal pressure, external soil loads, corrosion, and traffic loads<br>How StifPipe can be built to virtually any size or shape, including non-circular culverts<br>Field installation advantages: lightweight sections, easy assembly, and minimal equipment<br>Real-world case studies like the Arc Terminal project in Alabama and a custom rough-surface liner developed for Hong Kong<br>If you&#39;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.</p>
