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-11 (H or V). SikaProof® P-1201 System is cold-applied and post-applied onto the hardened reinforced concrete structure.

  • 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
  • Validated high watertightness
  • Easy to install with fully adhered joints (no welding required)
  • Cold applied
  • 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 steps

SUBSTRATE QUALITY

Reinforced concrete structure must be:

  • Hardened and of sufficient compressive strength, minimum 25 MPa (3600 psi)
  • With a minimum pull-off strength of 1.5 MPa (215 psi)
  • Dry, sound, clean and free of any contaminations (e.g. dust, oil, grease, release agent, etc.)
  • Free from surface defects (e.g. 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.
