Bonded FPO Waterproofing Membrane SikaProof® A+

SikaProof® A+ is a polyolefin (FPO) based sheet membrane for below ground waterproofing of reinforced concrete structures. A special hybrid bonding layer on the membrane forms a full and permanent dual bond with the concrete structure. The membrane can be pre or post-applied. Joints are sealed with cold-applied tapes or by thermal jointing using appropriate heating equipment.

Uses

SikaProof® A+ may only be used by experienced professionals.

The Product is used for:

• Damp-proofing, gas-proofing waterproofing and concrete protection for basements and other below ground concrete structures.

Suitable for use on:

• Precast reinforced concrete structures
• Cast-in-situ reinforced concrete structures
• Existing reinforced concrete structures

Characteristics / Advantages
