Most repairs complete in 1 to 3 weeks depending on the extent of damage and whether underpinning, grouting, or facing work is required.
Substructure and culvert repair addresses the below-deck components of a bridge or drainage structure, footings, abutments, wingwalls, bearing seats, and the culvert barrel itself, once they've begun to deteriorate. Depending on the specific problem, repair might involve micropile underpinning at the footing, grouting to fill voids around the structure, soil nails and shotcrete to stabilize headwalls, or slip-lining to restore a culvert's hydraulic capacity.
Across Dallas County, the most common driver is the same clay movement and drainage stress affecting retaining walls elsewhere in the county, compounded by scour where an older county-maintained culvert sits in an active drainage path. GSI's Dallas County substructure and culvert work typically includes:
Most repairs complete in 1 to 3 weeks depending on the extent of damage and whether underpinning, grouting, or facing work is required.
Cost depends on the specific damage, structure size, and repair method, which our engineers confirm after inspection before providing a fixed-cost proposal.
Yes. Every repair is designed by a licensed Professional Engineer and meets applicable Texas Building Code and bridge design requirements.
GSI offers 24/7 emergency response and can mobilize a crew within hours if scour or void loss threatens a structure's stability.
We inspect the substructure directly and, where needed, use subsurface investigation to confirm whether scour, void formation, or another cause is responsible.
In many cases, yes. Slip-lining and invert paving can restore a culvert's structural strength and hydraulic capacity without the cost and disruption of full replacement.
It depends on the extent of damage and repair method; we sequence work to minimize closures where possible.
Yes. Bearing seat repair typically involves removing the existing bearing, cleaning and repairing the seat, and reinstalling or replacing the bearing device.
A bridge substructure or culvert losing support underground often shows no warning sign until it's serious. Call (855) 599-5217 to get a Dallas County inspection from a licensed engineer.
