Aggregate Technologies Uses Hydrodemolition to Repair San Jacinto River Bridge
Aggregate Technologies recounts bridge damage and column repair.
Torrential rain over Texas from Tropical Storm Imelda flooded the San Jacinto River. Between 11 and 14 barges came unmoored, and some collided with the Interstate 10 bridge. The highway was closed while inspectors surveyed the damage, finding at least one column destroyed and another column severely damaged.
On the damaged 66-inch diameter column, five feet of the column above the water and 10 feet below needed to have the damaged concrete removed while preserving the rebar.
