Description

SikaProof® A-08 is an embossed polyolefin FPO sheet membrane for pre-applied fully bonded below ground waterproofing of reinforced concrete structures. Membrane thickness 0,8 mm. SikaProof® A-08 is coldapplied without heat or open flames to prepared substrates or onto formwork before fixing reinforcement and concrete placement. The membrane has self-adhesive longitudinal strips for bonding overlap joints and is laminated with a unique sealant and a nonwoven fleece backing layer which creates a bond with the cast concrete.

Uses

SikaProof® A-08 may only be used by experienced professionals. Waterproofing, concrete protection and gas resistant membrane for basements and other below ground concrete structures against ground water ingress. Suitable for use on:

• Reinforced concrete base slabs
• Reinforced concrete walls with both single and double-faced formwork
• Extension and reconstruction works
• Prefabricated structures
• Shotcrete structures

Advantages

• Can be used as a gas resistant membrane when used as part of a gas protection system according to BS8485:2007
• Cold-applied (no pre-heating or open flames) and pre-applied, before the reinforcement is fixed and the concrete is poured
• Fully and permanently bonded to the reinforced concrete of the main structure
• No lateral water underflow or migration between the concrete structure and the membrane system
• High watertightness tested according various standards
• Easy to install with fully adhered joints (no welding required)
• Temporary weathering and UV resistant
• Resistant to ageing
• High flexibility and crack-bridging ability
• Resistant to aggressive mediums in natural ground water and soil
• Can be combined with other approved Sika waterproofing / joint sealing systems
