Pollutants from our everyday life inevitably find their way into our fresh water systems. It is becoming increasingly important to prevent hazardous and harmful chemicals from contaminating our groundwater. Liners for canals, irrigation ditches, reservoirs, pipelines, culverts, dams, and other structures are now available as a spray applied coating that offer unmatched protection. SIPP (spray-in-place pipe) technology is available from SPI to retrofit older infrastructure that has degraded and may be allowing contaminants into our water systems. By relining existing pipes, vast amounts of time and money are saved while creating a liner that is structurally sound, and impervious to infiltrating water and pollutants.
