Avanti International
About
Avanti International, based in Webster, Texas, has specialized in injection grouts for infrastructure repair since 1978. The company develops and manufactures a portfolio of acrylic, urethane, cementitious, and epoxy grouts engineered for leak sealing, soil stabilization, and groundwater control. Its flagship product, AV-100 Chemical Grout, an acrylamide-based formulation, has been in continuous production since the company's founding and is widely used to stop infiltration in sanitary sewer systems. AV-275 Soilgrout provides urethane-based soil stabilization for geotechnical applications, while Ultrafine SD cementitious grout addresses fine-crack sealing where particulate grouts are required. Avanti serves four primary markets: municipal sewer systems seeking to eliminate infiltration, industrial facilities sealing concrete structure leaks, geotechnical projects requiring soil stabilization and groundwater control, and seawall and bulkhead rehabilitation involving void fill and erosion protection. Beyond product supply, Avanti offers classroom and field training programs, on-site technical assistance through regional field managers, and a Safe Operating Practices Program. The company coordinates with engineering firms, municipal agencies, and specialty contractors as both a materials supplier and technical resource for grouting applications.
