Secondary containment liners are an essential tool for use in applications where different types of hazardous liquids and chemicals may contaminate soil or water.
Secondary containment liners are used heavily in the oil and gas industry to prevent spills from leaching into groundwater through the use of stationary confinement and mobile containment berms.
Elastomeric polyurea is used in applications where a secondary containment liner is specified. It can be spray-applied to tanks for above ground and underground service to create an impermeable, seamless membrane. One of the advantages to using polyurea as a secondary containment liner is its capacity to flex, expand and contract, especially around pipe penetrations and over woven geotextile fabric.
