Description
ALSAN CIVIL Z71 is a two-component crack sealant made of fast-curing, very low viscosity polymethyl methacrylate (PMMA) resin.
UNITS PER SKID:
4.64 gal - 36
52.93 gal - 4
Material Use:
ALSAN CIVIL Z71 is a high-performance, two-component crack sealant formulated with fast-curing, low-viscosity polymethyl methacrylate (PMMA) resin. It is specifically designed for sealing cracks in concrete surfaces found in civil engineering structures and parking decks. Its UV-resistant formulation makes it suitable for both interior and exterior applications where long-term durability and exposure resistance are required.
System Components:
ALSAN CIVIL Z71 is used in conjunction with ALSAN RS CATALYST POWDER, which is essential for initiating the curing process. The catalyst is mixed into the resin at varying percentages depending on ambient temperature. ALSAN RS CLEANER is recommended for cleaning tools and equipment after application. This product is typically used as a standalone crack sealant but may be integrated into larger PMMA-based waterproofing or repair systems when specified by SOPREMA.
Applications:
ALSAN CIVIL Z71 is ideal for sealing static cracks in concrete substrates on bridges, parking structures, decks, and other civil infrastructure. It is particularly suited for environments where rapid curing and UV resistance are critical. The product is not intended for dynamic joints or areas subject to significant movement unless otherwise specified by the manufacturer.
Application Details:
Before application, the concrete surface must be fully cured (minimum 28 days), clean, dry, and free of contaminants such as dust, oil, curing agents, or formwork residue. The resin must be mixed thoroughly using a low-speed mechanical agitator (300 RPM) for two minutes before adding the catalyst. The catalyst dosage depends on ambient temperature:
- 20 to 35 °C (68 to 95 °F): 2%
- 10 to 20 °C (50 to 68 °F): 4%
- 0 to 10 °C (32 to 50 °F): 6%
For applications below 0 °C (32 °F), consult a SOPREMA representative.
Once mixed, the resin is applied directly over the crack using a flat squeegee or roller. The product has a pot life of approximately 15 minutes at 20 °C (68 °F), becomes rainproof after 30 minutes, and reaches full cure in about 2 hours. These times may vary depending on site conditions.
Special Notes:
- Environmental Conditions: Application should be performed in dry conditions with ambient temperatures above 0 °C (32 °F). Avoid application in high humidity or wet conditions.
- UV Resistance: ALSAN CIVIL Z71 is UV resistant, making it suitable for exposed applications without the need for additional UV protection.
- Thickness & Coverage: As a crack sealant, the product is applied in thin layers directly into cracks. Specific thickness and coverage rates are not provided in mils or ft²/gal due to the nature of the application, which is dependent on crack width and depth.
- Storage: Store indoors at 0 °C to 25 °C in original containers. Shelf life is approximately 12 months. Product is flammable—keep away from ignition sources.
- Safety: Use appropriate PPE and ensure adequate ventilation during application. Refer to the Safety Data Sheet (SDS) for full handling and safety instructions.
ALSAN CIVIL Z71 is a specialized material that can be integrated into broader PMMA-based repair and waterproofing systems when coordinated with other SOPREMA ALSAN products. Always consult with a SOPREMA representative for system compatibility and project-specific recommendations.
