Timber Pile Rehabilitation with Carbon Fiber Reinforcement – Portland OR

Crew applying carbon fiber reinforcement and epoxy materials to deteriorated timber piles during structural rehabilitation at a hillside residential complex.

A multi-building residential complex on a steep hillside in Portland, Oregon experienced significant timber pile deterioration, including rot and cross-sectional loss that reduced load-bearing capacity and threatened long-term stability. Access constraints made conventional pile replacement difficult, so a minimally invasive carbon fiber reinforced polymer (CFRP) rehabilitation approach was selected.

Repair scope and materials:

  1. Surface preparation removed deteriorated/rotted wood to create a stable repair substrate. Usrfiles

  2. Exposed timber received a wood preservative treatment to help resist future decay and improve durability. 

  3. Epoxy grouting and section rebuild restored original pile geometry using SRS-2000 Structural Epoxy Paste, creating a solid base for reinforcement.

  4. CFRP wrapping strengthened the piles using SRS-660 BI-Directional Carbon Fiber wraps, improving structural capacity and extending service life. Usrfiles

Result: The CFRP + epoxy repair method effectively restored structural integrity and load capacity while minimizing disruption—an efficient solution for challenging topography and environmental exposure.
