Protecting Infrastructure After the Flames

Understanding the Geohazard Risks After a Wildfire

Wildfires cause widespread destruction, leaving landscapes vulnerable to secondary hazards that threaten infrastructure, transportation networks, and communities. The loss of vegetation destabilizes slopes, increasing the likelihood of rockfalls, landslides, and debris flows. Additionally, soil erosion and hydrophobic soil conditions heighten the risk of flash floods during subsequent storms. Without proper mitigation, these hazards can lead to road closures, structural failures, and long-term damage to critical assets.

Geohazard Mitigation Strategies After a Wildfire

To minimize risks and restore stability after a wildfire, effective geohazard mitigation strategies must be implemented quickly. Our company specializes in post-wildfire response and employs proven techniques to protect infrastructure and communities. Our services include:

Rockfall Mitigation & Slope Stabilization

  • Installation of rockfall barriers, draped mesh, and attenuators to prevent falling debris from reaching roadways and structures.
  • Slope stabilization using soil nails, shotcrete, and micropiles to secure weakened slopes.
  • Scaling operations to remove loose material before it becomes hazardous.

Erosion Control & Drainage Solutions

  • Hydroseeding and erosion control blankets to promote vegetation regrowth and reduce soil loss.
  • Check dams, debris flow barriers, and culvert reinforcement to control water runoff and sediment movement.
  • Riprap and gabion installations to prevent embankment washouts.

Landslide & Debris Flow Prevention

  • Installation of debris flow barriers and retention systems to intercept material before it impacts infrastructure.
  • Compaction grouting and soil stabilization techniques to reinforce compromised ground.
  • Retaining wall construction and embankment reinforcement to support unstable slopes.

Bridge & Foundation Protection

  • Micropile and underpinning solutions to stabilize bridge foundations weakened by fire-induced soil erosion.
  • Sheet pile and tieback systems to reinforce embankments and prevent washouts near bridges and highways.
  • Structural repairs to ensure the longevity and safety of existing infrastructure.

Client Reviews

Geohazard Services for Transportation Infrastructure in Oregon

Just wanted to send a thank you to your crew as they were outstanding on our project up on Hwy 47 mp 6.3. I really appreciated the great communication and the hard work they did for us.

Geohazard Repair in Kentucky

GSI, thanks for another successful project. It is always nice to work with you and your field crews. We are currently experiencing flooding here in [this area], so I am sure we will be utilizing your services once again in the near future. The repair was “headache free” and that is very nice, to have a company and crew, come in do their job. You would be surprised how many contractors come in and are not as safety oriented and headache free as yours and for that reason, I am writing this email to let you know as a manager I appreciate the professionalism.

Organized and Dependable Crew Support in Vermont

You and Chris are awesome to work with! … Your crews that have been here are all very well organized, dependable and get their work done! GSI should be very proud of the crews they have working for them. Thanks again Perry for all your help and assistance!
