GeoStabilization International provides industry-leading expertise in bridge substructure and culvert repair, offering design-build solutions that restore aging infrastructure without major traffic disruptions or extensive demolition.
Our teams have successfully repaired and rehabilitated bridge abutments, piers, back walls, wing walls, and culverts across North America. We engineer and install solutions for failures caused by:
Common mitigation methods include micropiles, soil nails, shotcrete, grouting, lightweight fill, and GRS technology, each selected to address specific site conditions and project goals.
Culverts play a critical role in drainage and hydraulic performance beneath roads, railways, and embankments. Over time, they may experience invert deterioration, joint separation, or loss of backfill support. GSI’s culvert repair services extend structural life without costly replacement. Our techniques include:
Micropile underpinning to re-establish load-bearing support at culvert ends or beneath undermined barrels.
Permeation grouting and compaction grouting to fill voids and stabilize soils around deteriorated culverts.
Slip-lining and invert paving to restore hydraulic capacity and internal structural strength.
Soil nails and shotcrete facings to stabilize headwalls, embankments, and approaches.
Each repair is designed for long-term performance while maintaining flow and minimizing stream disturbance.
Bridge abutments often weaken over time due to scour or excessive earth pressure. GSI’s engineers evaluate each site and deploy customized stabilization systems, such as micropiles, soil nails, and shotcrete facings, to restore integrity and support. Most abutment undermining repairs can be completed while keeping the bridge open to traffic.
Wing walls can fail from poor drainage, foundation movement, or corrosion of structural elements, resulting in cracking, bowing, or separation. GSI stabilizes wing walls using soil nails, shotcrete, and grouting to reinforce subsoils and realign structural geometry. These solutions improve safety, minimize excavation, and extend service life.
As abutments age and show signs of concrete deterioration or settlement, refurbishment offers a cost-effective alternative to full replacement. GSI’s bridge abutment refurbishment services restore bearing capacity, reduce permitting requirements, and allow work to occur outside of the stream channel with little to no demolition.
GeoStabilization International has revolutionized bridge rehabilitation by enabling aging structures to be strengthened in place, eliminating the need for costly replacement. Our repair systems apply to bridges and culverts constructed of wood, concrete, steel, gabions, or stone.
Using advanced technologies such as micropiles, soil nails, and grouting, GSI provides durable, rapid solutions that reduce downtime, preserve existing assets, and restore structural reliability.
GeoStabilization International utilizes the most advanced technologies for bridge substructure repair and culvert rehabilitation, extending the service life of critical infrastructure by up to 75 years.
GSI’s in-house geotechnical engineers, construction specialists, and field crews deliver turnkey, design-build solutions that meet structural, environmental, and schedule demands.
If you require bridge substructure repair or culvert rehabilitation, GeoStabilization International can provide a no obligation site assessment and fixed-cost proposal.
