KingProof PVPL®
A flexible PVC waterproofing membrane for water retaining structures.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingProof PVPL is a reinforced flexible polyvinyl chloride (PVC) waterproofing sheet with high UV resistance in the top layer and enhanced flexibility and tensile strength from the bottom layer, for lining of water retaining structures.
Where to use
KingProof PVPL can be used for submerged conditions and in contact with potable water for lining of:
- Water tanks.
- Reservoirs.
- Artificial lakes.
- Canals.
Why use it
- Excellent UV resistance.
- Resistant to roots and microorganisms.
- Stable even at a wide temperature cycles.
- Excellent mechanical properties.
- Long life expectancy.
- Easily welded using hot air.
How to use
Method of use
KingProof PVPL must be installed by experienced and qualified personnel.
Surface preparation
Surface must be clean, sound and dry. Remove any poorly attached materials or contaminations. Cover or remove any sharp elements which could damage the PVC membrane. A compatible clean and dry separation layer should be placed between the substrate and the PVC membrane.
Application
KingProof PVPL can be applied by two methods
Fixing method
The membrane is mechanically anchored in the overlapping seams, and loosely laid under ballast.
Welding method
Use a manual or an automatic hot air welding machine with a pressure roller to join the overlapping membrane sheets together. The width of the joint must be at least 30 mm.

Adjust the temperature and machine speed of the air welding machine according to the ambient conditions. To ensure all the welding is done correctly, all seams must be tested with screw driver or steel needle after the joint has cooled. Unwelded points must be repaired with a welding tool.
Limitations and notes
KingProof PVPL should not be in direct contact with bitumen, oil, solvent and tar as well as plastics other than PVC. On these surfaces it requires a separation layer of non- woven fabric (> 300 g/m²).
Coverage, packaging and storage
Packaging
Each roll is packed in clear LDPE film
KingProof PVPL120: 1.2 mm x 2.00 m x 20 m. KingProof PVPL150: 1.5 mm x 2.00 m x 20 m. KingProof PVPL180: 1.8 mm x 2.00 m x 15 m.
Storage
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature.
Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult KingKrete's Technical Services Department.
Health and safety
As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs. Treat splashes to eyes
and skin immediately. If accidentally ingested, seek
medical attention. Reseal containers after use. Use in well ventilated areas and avoid inhalation.
