Municipalities are discovering rapid degradation of infrastructures in wastewater collection and treatment facilities due to the infiltration of water from the surrounding environments. Wastewater facilities are not only wet, but also experience hydrostatic pressure conditions under normal service. Rehabilitation of these facilities by in situ methods, including use of grouting, is used to return structures to their original working conditions. Grouting is the most widely used leak-control method in small to large wastewater treatment plants and other collection systems. Application of grouts to leaking joints is considered a challenge, and performance must be evaluated using model tests representing close to actual field conditions. The grouted soil must also be durable enough to withstand the effect of severe physical and chemical environmental conditions to which it will be subjected to during the service life. This verification evaluated Avanti Internationals AV-118 Duriflex Acrylic Chemical Grout under laboratory conditions at the Center for Innovative Grouting Materials and Technology (CIGMAT) Laboratories at the University of Houston. Testing was conducted on grout and grouted sand over a period of 6 months to evaluate the grouts performance under various simulated physical and chemical environments.
