Description USES SikaProof® A 08 is ideal for: Damp-proofing, waterproofing, and protecting concrete in basements and other underground structures. Precast reinforced concrete structures. Cast-in-place reinforced concrete structures. Existing reinforced concrete structures. FEATURES Dual Bond: Provides a full, permanent mechanical and chemical bond to concrete. Pre/Post Application: Can be applied either before or after concrete placement. No Lateral Water Migration: Prevents lateral water movement between the concrete and the membrane. Easy Installation: Quick and simple to install. High Flexibility: Excellent crack-bridging properties. Superior Watertightness: Tested to meet high watertightness standards. Durability: Resistant to aggressive conditions in natural groundwater and soil. Weather and UV Resistance: Temporarily resistant to weathering and UV exposure. Compatibility: Can be combined with other Sika® waterproofing and joint sealing systems. SUSTAINABILITY Specific Environmental Product Declaration (EPD) in accordance with EN 15804, independently verified by BRE Global. Contributes to LEED® v4 credits for Materials and Resources (MR) in Building Product Disclosure and Optimization and Material Ingredients.
