Aliva-257 concrete spraying machine

Aliva-257 is the universal machine for dry and wet shotcrete application by thin-stream process. The new and very compact design of the machine impresses through its dimensions, weight and performance. With just 750 kg. and dimensions as little as a small dry shotcrete machine, the Aliva-257 fits on every job site and easy to install and operate

With its unbelievable output capacity range from 0.7 to 9.6 m3/h (with 3 rotor sizes) the machine work on small concrete renovation work as efficient as on big slope protection or in mines. Is it for thin layer concrete renovation with the 2.5l rotor up to slope protection of an excavation with the 12l rotor, With the AL-257 one has always the right equipment at hand. Less maintenance and wear cost makes it the ideal shotcrete machine for all applications


- Dry and wet shotcrete

- concrete repair

- Swimming ponds, pools

- Slope stabilization and excavation support

- Mining, tunneling

- Refractory applications


The Aliva-257 is equipped with a fully automatic lubrication system for the rotor-discs. The rotor-speed is adjusted with a frequency converter and therefore, can be adjusted to every specific need on the job. The machine has an emergency button which stops the turning of the rotor and closes the main valve of the air supply, conform the EU standards.

New sealing system

The machine also has the high quality steel on steel sealing system. Experience has shown up to 10 times less wear on the steel plates, depending on material, output capacity, hose diameter and compressed air supply. This again leads to less standstill time and wear cost and therefore to more economical spraying operation.
