Tank Sealings
APRO Industrie's PVC membrane sealing is an innovative and sustainable solution for a variety of liquid storage needs. Unlike other systems, the tank's metal sheets only provide structural support, while the internal liner ensures an airtight seal. This process can be used for both new projects and existing tanks, including damaged ones. It makes it possible to extend the life of a tank or give it a new lease of life while reducing the costs associated with complete reconstruction.
- Suitable for new and existing tanks (welded steel, concrete, etc.)
- Cost-effective and quick solution
- Long-lasting protection against leaks and corrosion
- Compliant with specific regulatory requirements for each sector
- Replacement possible with APRO
What is a PVC liner ?
A PVC waterproof liner is a flexible membrane that ensures the watertightness of storage tanks. It is suitable for a variety of applications and provides optimal protection against leaks while adapting to the specific properties of the stored liquids.
Liner composition and characteristics
PVC tank liners are designed using materials selected according to the intended storage application. They are manufactured as one piece in the factory to the exact dimensions of the tank, thus ensuring a perfect seal. APRO Industrie systematically carries out compatibility analyses to ensure that the materials comply with regulatory requirements, particularly for storing drinking water and for use in the food industry.
