Polyolefin (FPO) waterproofing membrane designed for insulation of reinforced concrete structures below the ground level. It is used for free laying on the prepared substrate or in formwork before mounting the reinforcement and concreting. A special hybrid bonding layer on the membrane creates a permanent bond with the fresh concrete. Special tapes are used to seal the plant.

Features

• pre-installed before assembly of reinforcement and concreting
• creates a double bond with fresh concrete: mechanical and adhesive
• high flexibility and crack-bridging capacity
• no water penetration between the concrete structure and the membrane system
• high water resistance
• adheres fully and permanently to the reinforced concrete structure
• resistance to aggressive ingredients naturally occurring in soil and groundwater
• easy to install
• temporary resistance to weather conditions and UV radiation
• can be combined with other Sika approved waterproofing / sealing systems

Application

For use as damp, water-repellent and concrete protection for foundations and other underground concrete structures, it protects against the ingress of groundwater. Ideal for: reinforced concrete slabs below ground level, reinforced concrete walls below ground level with formwork on one or both sides, extension or reconstruction, and for prefabricated structures.
