Innovations in Culvert Rehabilitation: Wet Layup & StifPipe

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.
