Hanson Pipe Provides Box Culverts to Replace Deteriorating Pipes
Irving-based Hanson Pipe & Precast is providing precast concrete box culverts to the Central Texas Garden Ridge community to replace five deteriorating corrugated metal pipes that caused a 5-ft sinkhole to form on a roadway.
The cycle of corrosion/erosion of the metal culverts lead to portions to be eaten away. As this occurred, openings were created in the metal pipe allowing its surrounding bedding material to be washed away and ultimately became large enough to cause a structural failure of the roadway base and roadway on top of it.
