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 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 reinforced 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)
  • Good tear and impact resistant properties
  • 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

Application

Application Information

Ambient Air Temperature

+ 5 °C min. / + 35 °C max.

Substrate Temperature

Substrate bonding surface: minimal +5 °C ( Refer to important considerations for more information)

Substrate Moisture Content

≤ 6 % parts by weight. No rising moisture

Dew Point

The substrate temperature must be at least 3°C above the dew point to reduce the risk of condensation and reduced adhesion.
Application steps

EQUIPMENT

  • Tape measure
  • Marking pen
  • Razor knife
  • Scissors
  • Pressure roller
  • Clean lint-free cloth
  • Metal straight edge for cutting
  • Protective sheet for cutting

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, surface treatments and loose friable material.

Weak cementitious substrates must be removed and surface defects such as blow holes and voids must be fully exposed.
