Flexible polyolefin (FPO) self-adhesive sheet membrane for post-applied fully bonded below ground waterproofing.

Jump to:
+44 (0)1707 394444 Website

Application

Damp-proofing, waterproofing and concrete protection for basements and other below ground structures against ground water ingress. Suitable for use on:

  • Vertical reinforced concrete walls.
  • Extensions and reconstruction works.
  • Prefabricated structures.

Description

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. It 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.


Features and benefits:

  • Membrane thickness 1.2 mm.
  • Will restrict the ingress of radon into buildings from naturally occurring sources.
  • 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.


Approvals/ standards:

  • CE Marking and Declaration of Performance to EN 13967 - Flexible sheets for waterproofing – Damp proofing and basement tanking.
  • Agrement Certificate, SikaProof® P,BBA,Certificate No.13-5075.
  • Test Report, Functionality, SikaProof P-12, WISSBAU, No. 2013-253.
  • abP Approval, SikaProof P-12, Report No. MPANRW- 2211463-1.
