SikaProof®-808

PRE-APPLIED FULLY BONDED FPO SHEET MEMBRANE FOR BASEMENT
WATERPROOFING

SikaProof®-808 is a FPO based sheet membrane for below ground waterproofing of reinforced concrete structures. It is loosely laid onto a prepared substrate below the base slab before fixing reinforcement and casting concrete. A special hybrid bonding layer on the membrane forms a permanent bond with the fresh concrete and prevents lateral water migration between the membrane and the concrete structure. Overlap joints are sealed using cold-applied tapes or by thermal jointing. The total thickness is 1,00 mm.

  • Pre-applied: Fixed before placing reinforcement and casting concrete
 
  • A+ Technology: Integral functional layer for chemical and mechanical bond with concrete structure
  • High flexibility and crack-bridging capabilities
  • No lateral water migration between concrete structure and membrane system
  • Easy to install with fully adhered joints
  • Overlap joints are sealed using thermal jointing or cold-applied tapes

APPLICATION INSTRUCTIONS

IMPORTANT

Strictly follow installation procedures

Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

SUBSTRATE QUALITY

SikaProof®-808 membrane must be applied on a sufficiently stable substrate to avoid movement during the construction works.

The substrate surface must be smooth, uniform and clean. Use Geotextile ≥300 g/m2 to protect the Product from sharp aggregates on the blinding concrete surface.

The substrate can be damp or slightly wet, avoid ponding water.

APPLICATION

IMPORTANT

Application by trained personnel

The application of this Product must only be carried out by an applicator that is trained or approved by Sika. The applicator must also be experienced in this type of application.
 

IMPORTANT

Unsuitable weather conditions for application

Do not install the membrane during continuous or prolonged rain, snowfall or sandstorm. 
 

IMPORTANT

Penetrations and construction joints

Additional Sika joint sealing solutions must be used for connections around penetrations and for construction joints.
 

 

IMPORTANT

Covering the membrane system

Permanent exposure to UV light will reduce the performance of the membrane system.

  1. Concrete must be placed within 60 days after membrane system installation.
  2. Proper concrete installation (mix design and workmanship) is required to achieve optimum bond of the membrane system to the concrete.

Reference must be made to the Sika Method Statement: SikaProof®-808
