SikaProof A-08 – 0.8mm FPO Fully Bonded Waterproof Membrane for Below Ground Concrete

This embossed FPO (Flexible Polyolefin) sheet membrane is designed for pre-applied, fully bonded waterproofing of reinforced concrete structures. At 0.8 mm thickness, SikaProof A-08 creates a continuous barrier that bonds directly to cast concrete, preventing water migration and ensuring long-term protection.

Ideal for professional below-ground waterproofing, this membrane is cold-applied without heat or flames and features self-adhesive overlap joints for fast, secure installation. It provides high resistance to groundwater, gases, and structural movement, making it suitable for basements and critical structural waterproofing.

Key Benefits:

• Fully bonded system prevents lateral water migration
• 0.8 mm FPO membrane for durable waterproofing
• Cold-applied – no heat or open flame required
• Self-adhesive overlap strips for easy installation
• High watertightness and crack-bridging capability
• Resistant to groundwater, soil contaminants, and ageing
• Gas resistant (methane, CO₂, radon barrier capability)
• Suitable for pre-applied waterproofing systems

FAQs

What is SikaProof A-08 used for?
It is used for below-ground waterproofing of reinforced concrete structures such as basements and slabs.

How is it installed?
It is pre-applied to formwork or substrate before reinforcement and concrete placement, then bonds to the poured concrete.

Does it require heat or welding?
No, it is cold-applied and uses self-adhesive strips for jointing.

Can it resist ground gases?
Yes, when installed correctly it can act as a gas barrier against methane, CO₂, and radon.

What substrates is it suitable for?
It is designed for reinforced concrete slabs, walls, prefabricated elements, and shotcrete structures.
