Texas agencies appear repeatedly in the recent record—the City of San Antonio, Collin County, the Texas Department of Transportation, and Harris County Department of Education all posted opportunities within the past four months. The work being solicited ranges from polyurethane and silicone crack sealants for municipal streets to hot-poured joint sealers for state bridge and pavement applications, with quantities typically measured in drums, kits, or gallons suitable for field application.
