SikaProof® P-12
FPO self adhesive sheet membrane for post-applied fully bonded below ground waterproofing
SikaProof® P-12 is a flexible polyolefin (FPO) self-adhesive sheet membrane for post-applied fully bonded below ground waterproofing of existing reinforced concrete structures. Membrane thickness 1,2 mm. SikaProof® P-12 is pre-coated with an adhesive sealant layer and is cold applied onto primed concrete structure by a simple peel and stick process by using SikaProof® Primer-01 as a system primer.
- Post-self-adhered, fully bonded on existing concrete structures
- No lateral water underflow between the concrete structure and the membrane system
- High flexibility and crack-bridging
- Validated high watertightness
- Easy to install with fully adhered joints (no welding required)
- Cold applied (no heat or open flames)
- Temporarily resistant to weathering and UV-light during construction
- Highly durable and resistant to aging
- Resistant to aggressive elements in natural ground water and soil
- Can be combined with other approved Sika Waterproofing / Joint Sealing Systems

SUBSTRATE QUALITY
Concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm2) with a minimum tensile adhesion strength of 1,5 N/mm2.
Substrate must be even, level, clean, dry and free of all contaminants such as dirt, oil, grease and surface treatments.
Weak cementitious substrates must be removed and surface defects such as blow holes and voids must be fully exposed and repaired accordingly.
APPLICATION
Substrate preparation
If the substrate does not fulfil the requirements the surface must be pre-treated prior to the application, in order to prevent any subsequent damage to the waterproofing membrane sheets. The use of SikaProof® Primer-01 is required to ensure an optimal, durable bond to the substrate (this primer is a defined system component).
Installation procedure
Strictly follow installation procedures as defined in method statementsand, insatllation or working instructions which must always be adjusted to the actual site conditions.
Installation method - General
After substrate conditions and priming have been fulfilled, the waterproofing membrane is installed by peel & stick method onto horizontal / inclined / vertical hardened concrete substrates. The membrane sheets are overlapped with the following sheet. No heat or open flames are required for installing any part of the membrane system.
T-joints, transitions and corners
All T-joints and transitions must be sealed additionally with a strip or patch of SikaProof® ExTape-150.
Detailing
Form all details and connections using the appropriate SikaProof® ancillary products outlined in the ‘Method Statement - SikaProof® P
Construction and expansion joints
For sealing these types of joints, use additional Sika® Joint Solutions.
Inspection and quality control of installation
A final inspection before protecting and backfilling must be carried out to ensure the complete membrane system has been correctly installed, and any damage repaired.
Backfilling protection
After installation is completed SikaProof® P-12 system must be protected with an appropriate protection sheet as soon as possible or at the latest within 90 days or before backfilling.
