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.
