Fastfill – Structural Repair Mortar

Rapid setting, high strength, fibre reinforced, shrinkage compensated waterproof mortar for structural repair and reinstatement of concrete. CE marked in accordance with BS EN 1504-3 Class R4. Uses Durable repair of concrete subject to heavy wear such as roads, runways, bridges, decks, floors and footpaths. Suitable for repair methods 3.1, 3.2, 4.4, 7.1, 7.2 as defined by BS EN 1504-3. When bulked out produces a pour-able mortar or micro concrete especially for potable water applications.

Advantages
• Incorporates the latest proven cement chemistry, microsilica, fibre and styrene acrylic copolymer technology.
• Pre-packaged material only requiring mixing with water on-site. Can be bulked out with sand or aggregate.
• Rapid strength development, even at sub-zero temperatures. Allows early return to service.
• Sets in 10 minutes at 20°C yielding a durable, high strength mortar.
• Repairs can be walked on in 1 hour, and subject to vehicular traffic in 2 hours. • Ideal for use in tidal applications due to rapid setting properties.
• High bond strength exceeds tensile strength of concrete, ensuring monolithic performance of the repair.

Sika 4 and Sika 4A

Sika®-4a is a rapid setting waterproofing admixture. When mixed with ordinary Portland cement and water, it sets rapidly to seal areas of severe water infiltration through concrete, rock or masonry. USES Sika®-4a is used as preliminary waterproofing work on wet surfaces or where there is general infiltration of water, prior to the application of subsequent cementitious render or gunite. Typical applications are tunnels and culverts, mine galleries, water reservoirs, concrete pipes and manholes. It can also be used in quick setting mortar for assembly work, e.g. for fixing anchors, bolts and other fitting subject to early loading in rock or concrete.

Benefits
• Ready to use
• Quick setting
• Prevents cement wash out
• Does not contain chlorides
• Excellent resistance to backwater pressure

Advantages
• Rapid setting for rapid leak plugging and/or fixing
• Ready to use, just add clean water and ordinary Portland cement
• Does not contain chloride
