KingProof PVFS®
High-performance, fully bonded PVC membrane co-extruded with a swelling non-woven for below-grade waterproofing.
Overview
KingProof PVFS is a high-performance, pre-applied waterproofing membrane composed of a PVC sealing layer co-extruded with an advanced swelling non-woven geotextile. This non-woven layer incorporates water-reactive polymers that swell on contact with moisture, providing self-sealing and self-healing capabilities. KingProof PVFS is installed before the steel reinforcement is fixed and the concrete is poured. The unique configuration of the membrane enables a full mechanical bond with freshly poured concrete, eliminating water migration between the membrane and the structure. It offers superior resistance to water, gases (e.g. radon), salts and chemical exposure.
Applications
- KingProof PVFS can be used in both pre-applied and post-applied configurations and is particularly suited to:
- Underground waterproofing – foundations, basements, retaining walls, floor slabs, car parks and garages
- Sealing of precast concrete elements to enhance joint tightness and durability
- Protection of concrete exposed to aggressive groundwater or chemically active environments
- Marine and salt-contaminated environments
Advantages
- Fully bonded system – permanent mechanical bond with freshly poured concrete
- Can be used both pre- and post-applied
- Swelling fleece offers self-healing properties, maintaining integrity after minor damage or movement
- Excellent mechanical properties; tough and durable
- Excellent chemical resistance; suitable for saline environments
- Effective barrier against radon-gas infiltration
- High flexibility and crack-bridging capacity
- Compatible with bitumen
