SikaProof® P-1201 System

FULLY BONDED, POST‐APPLIED FPO SHEET MEMBRANE WATERPROOFING SYSTEM FOR BASEMENT AND BELOW GROUND STRUCTURES

SikaProof® P-1201 System is a fully bonded composite sheet membrane waterproofing system for reinforced concrete structures. It consists of an embossed flexible polyolefin (FPO) based membrane SikaProof® P-1200 and a 2 component PU adhesive SikaProof® Adhesive-01. SikaProof® P-1201 System is cold-applied and post-applied onto the hardened reinforced concrete structure, without use of heat or open-flames. Suitable for use in hot and tropical climatic conditions.

  • Fully bonded onto the hardened concrete structure
  • No lateral water underflow between the reinforced concrete structure and the membrane system
  • Highly flexible with crack‐bridging abilities
  • High watertightness tested according various standards
  • Easy to install with fully adhered joints (no welding required)
  • Cold applied (no heat or open flames required)
  • Temporary resistant to weathering and UV‐light during construction
  • Resistant to aging
  • Resistant to aggressive mediums and gases in natural ground water and soil
  • Can be combined with other approved Sika Waterproofing / Joint Sealing Systems

Application steps

SUBSTRATE QUALITY

Reinforced concrete structure must be:
  • Hardened and of sufficient compressive strength, minimum 25 N/mm2
  • With a minimum pull-off strength of 1.5 N/mm2
  • Dry, sound, clean and free of any contaminations (example: dust, oil, grease, cement laitance, release agent, etc.)
  • Free from surface defects (example: blowholes, voids, honeycombing, cracks, protrusions, etc.)

SUBSTRATE PREPARATION

The concrete or other suitable cementitious substrate must meet the defined substrate quality. 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 membrane sheets.
