The Applications of Shotcreteing

Condor Projects is a team of highly experienced engineers who provide ground stabilisation and a variety of other specialist geotechnical services. A prime example is shotcreteing, which is the process of spraying concrete directly onto existing bridges, retaining walls and other structures to repair damage and significantly extend their lifecycle. 


What is shotcreteing?

As the name suggests, shotcreteing involves the liquid concrete being shot straight onto a surface. This is done at high velocity and achieved using powerful specialist equipment, allowing shotcreteing to be applied to horizontal and vertical surfaces alike.

The combination of the sheer force, speedy placement and instant compaction of the material means that shotcreteing can be applied to curved and overhead surfaces too, such as tunnels and domes.


Is shotcreteing a new system?

Far from it, as shotcreteing has actually been around for over one hundred years. However, the last century and recent years in particular have seen the process adapt and improve, which has resulted in the highly effective and versatile version that we use today.

The modern process of shotcreteing is highly precise and efficient, which means fast application, fewer workers and vehicles involved, and also minimised costs for the customer. As a result, shotcreteing is more economical than the traditional application of concrete and perfect for all kinds of construction projects, both domestic and commercial.


Shotcreteing is strong and reliable

If you require any kind of concrete structure repairing, shotcreteing by Condor Projects is the solution. As well as being designed to return the surface to its previous level of structural stability or even better, shotcrete is also resistant to fire, mould and worms. This means that it remains strong, impenetrable and sturdy for many, many years to come, plus its low levels of permeability ensure that it doesn’t deteriorate even in the dampest and coldest climates.


Dry and wet concrete systems

Condor Projects makes sure to give customers options, which is why you can choose from either the dry or wet form of shotcrete. The dry system follows the process of placing the dry ingredients into a hopper and then propelling them through a hose to the nozzle, where the water is added manually. The dry ingredients and water fully mix as they hit the surface. Meanwhile, the wet system uses pre-prepared concrete, with compressed air introduced at the nozzle to thrust the mixture onto the receiving surface.


Which system should I choose?

It tends to be down to the size of the project. If it’s a small or medium job, the dry system will work well because it can be set up and shut down very easily. If you require more extensive work, the wet system is more suitable because the required volume of concrete is prepared beforehand, speeding up what could otherwise be a relatively lengthy preparation stage.
