PVC Liners
APRO Industrie’s PVC liner system is an innovative and durable solution for a wide range of liquid storage applications. Unlike other systems, the steel shell of the tank serves only as the structural support, while the internal liner ensures reliable watertight sealing. This process can be used for both new projects and existing tanks, including deteriorated structures. It makes it possible to extend the life of a tank or extend operational life while reducing the cost of full tank replacement.
- Suitable for new and existing tanks (welded steel and concrete tanks)
- Fast and cost-effective installation
- Long-lasting protection against leaks and corrosion
- Designed to meet sector-specific regulatory requirements
- Replacement and refurbishment services available
What is a PVC liner?
A PVC liner is a flexible waterproof membrane that ensures the watertightness of storage tanks. It is suitable for a variety of applications and provides optimal protection against leaks while compatible with the characteristics of the stored liquid.
Liner composition and characteristics
PVC tank liners are designed using materials selected according to the intended application. They are prefabricated as a single piece in the factory to the exact dimensions of the tank, thus ensuring reliable watertight performance. APRO Industrie performs systematic compatibility analyses to ensure that the materials comply with regulatory requirements, particularly for storing drinking water and for use in the food industry.

FAQs - PVC Liners
What types of liquids can be stored with a PVC liner system?
PVC membranes are suitable for storing a variety of liquids, including drinking water, industrial effluents, compatible chemicals and certain oils, subject to a prior compatibility study.
Are PVC liners resistant to all products?
Although PVC membranes are highly resistant, they must be suitable for the liquids being stored. A preliminary analysis ensures they are fit for purpose.
What is the lifespan of a PVC liner?
The lifespan of a PVC liner depends on how it is used and maintained. With proper maintenance, it can typically provide a service life of several decades.
