SikaProof®-808

Fully bonded FPO sheet membrane for below ground waterproofing

SikaProof®-808 is a fully-bonded FPO sheet membrane for external below-ground waterproofing of reinforced concrete structures. The membrane can be pre-applied for example below a base slab or on a wall with lost formwork, or post-applied with the SikaProof® Adhesive-02 onto existing reinforced concrete structures. A special hybrid bonding layer on the membrane forms a permanent dual bond with the concrete structure to prevent lateral water migration between membrane and concrete. Overlap joints are sealed using cold-applied tapes or by thermal jointing.

  • Can be used as a pre-applied and post-applied system
  • A+ Technology: Dual bond (mechanical and chemical) with concrete structure
  • High flexibility and crack-bridging capabilities
  • No lateral water underflow between concrete structure and waterproofing system  
  • Easy to install with fully adhered joints
  • Overlap joints are sealed using thermal jointing or cold-applied tapes

Application steps

SUBSTRATE PREPARATION

Preconditions

The substrate is sufficiently stable to avoid movement during the construction works.

The substrate surface must be smooth, uniform and clean.

  1. IMPORTANT The substrate may be damp or slightly wet but avoid ponding water. Apply a Geotextile ≥ 300 g/m2 to protect the Product from sharp aggregates on the blinding concrete surface.

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

Reduced Product performance due to application in unsuitable weather conditions

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

IMPORTANT

Risk of leaks due to insufficient sealing of penetrations and construction joints

  1. Use additional Sika joint sealing solutions for connections around penetrations and for construction joints.

IMPORTANT

Reduced system performance due to permanent UV exposure

  1. The membrane must not be exposed to direct sunlight for more than 60 days.
  2. Proper concrete installation – mix design and workmanship – is required to achieve optimum bond of the membrane system to the concrete.
