Certificate type
Flexible polyolefin (FPO) sheet membrane for pre-applied fully bonded below ground waterproofing.
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.
