Aliva products

Aliva is Normet's product range of shotcrete equipment, developed for construction, mining and tunnelling. The range includes rotor machines for dry-mix and wet-mix spraying, spraying arms (manipulators), dosing units for liquid admixtures and mortar machines. The equipment is supplied by Normet International Ltd, Aliva Equipment, in Widen, Switzerland. According to the manufacturer, it is designed to meet needs in concrete repair, pool construction, construction, rock and slope stabilisation, and tunnelling and mining, where precise control of the shotcrete is essential.

The manufacturer describes the rotor machines as robust and easy to set up, operate and clean after use. The series ranges from the compact Aliva 237 to the Aliva 267:

• Aliva 237: for dry-mix spraying, 0.2–4 m³/h
• Aliva 252: 5–11 m³/h
• Aliva 257: for dry-mix and wet-mix spraying, 0.7–9.6 m³/h
• Aliva 201: for mounting on a pressure silo, 2–5 m³/h
• Aliva 267: for dry-mix and wet-mix spraying, 4–21 m³/h

Normet Piccola (0.8–3.5 m³/h) and Normet GM (3.5–8 m³/h) are also part of the range. The machines are used for repairing concrete structures, rock support, sealing wet areas, slope stabilisation and lining in mines.

For mechanised spraying, the range offers the Aliva 101 spraying head for excavators, the Aliva 302.1 spraying arm for mines and small tunnels and the telescopic Aliva 503.3 spraying arm, both with a reach of 2 to 9 m. The Aliva 403.3 and Aliva 403.6 dosing units provide precise dosing of liquid admixtures and can be synchronised with the machine's concrete output; the Aliva 403.6 doses 30–700 l/h. The mortar machines cover concrete repair, grouting and jointing work. The Aliva 101, the rotor machines and the dosing units can be combined into complete, self-contained spraying systems.
