    Certificate type

Flexible polyolefin (FPO) sheet membrane for pre-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 concrete structures. Suitable for use on:

  • Precast reinforced concrete structures.
  • Cast-in-situ reinforced concrete structures.

Description

SikaProof® A+ 08 is a flexible polyolefin (FPO) based sheet membrane for below ground waterproofing of reinforced concrete structures. A special hybrid bonding layer on the membrane forms a full and permanent dual bond with the concrete structure. Joints are sealed with cold-applied tapes. The total thickness is 1.35 mm with a membrane thickness of 0.80 mm.


Features and benefits:

  • Dual bond: full and permanent mechanical and chemical bond with the concrete structure.
  • Can be used as a pre-applied system.
  • No lateral water migration between concrete and membrane.
  • Fast and easy installation.
  • High flexibility and crack-bridging capabilities.
  • High watertightness tested according to various standards.
  • Good resistance to aggressive conditions in natural ground water and soil.
  • Temporarily resistant to weathering and UV exposure.
  • Can be combined with other approved Sika® waterproofing and joint sealing systems.
  • Environmental Product Declaration (EPD) in accordance with EN 15804. EPD independently verified by BRE Global.


Approvals/ standards:

  • CE marking and declaration of performance based on EN 13967:2012 Flexible sheets for waterproofing — Plastic and rubber damp proof sheets including plastic and rubber basement tanking sheet — Definitions and characteristics.
  • Watertightness functional test PG FBB Part 1, WISSBAU, Test report No. 2019-231-5-1.
  • Watertightness functional test PG FBB Part 1, WISSBAU, Test report No. 2019-231-4-1.
