Description :

SikaProof® A+ 12 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 coldapplied tapes or by thermal jointing using appropriate heating equipment. The total thickness is 1.75 mm with a membrane thickness of 1.20 mm.

Uses :

SikaProof® A+ 12 may only be used by experienced professionals.
The Product is used for:

• Damp-proofing, waterproofing and concrete protection for basements and other below ground concrete structures.
• Can be used as a ground gas resistantmembrane when installed as a waterproofing
• membrane fully bonded to concrete according to BS:8485:2015+A1 2019.
• Will restrict the ingress of radon into buildings from naturally occurring sources
• Suitable for use on:
• Precast reinforced concrete structures
• Cast-in-situ reinforced concrete structures
• Existing reinforced concrete structures
• Can be used as a ground gas resistantmembrane
  when installed as a waterproofing
• membrane fully bonded to concrete according to BS:8485:2015+A1 2019.
• Will restrict the ingress of radon into buildings from naturally occurring sources

Characteristics/Advantages :

• Dual bond: full and permanent mechanical and chemical bond with the concrete structure
• Can be used as a pre and post-applied system
• Joints can be sealed using thermal jointing
• No lateral water migration between concrete and membrane
• Excellent barrier to radon
• Fast and easy installation
