What is sprayed concrete?

Sprayed concrete is a way of applying the material that ensures it can be supported without the need of form work. It is also called Gunite or Shotcrete. The process of Gunite was made in 1895, and then fully available in the early 1900s. The material is made into a dry state using compressed air to a nozzle. Water is then added to mix to hydrate the concrete before applying with velocity.

Shotcrete was developed during the 1940s, but wasn’t used generally until the 1970s. This mix is applied in wet form, and pumped through a nozzle where air is added to spray onto the desired area. The accelerators used in this process aid the application in overhead situations, making it particularly useful for helping with gain requirements in tunnelling.

Churchill Concrete Technology has extensive experience with these methods of applying concrete. It is found that a lot of the time, these ways are far superior to general application.

So why choose sprayed concrete?
There are a number of reasons why you should opt for this method over others. Not only does it have high strength, high durability and low permeability, but it also has good bond strengths and adhesion. The method works out to be far cheaper too; the reduction in formwork saves you time as well as money.

On top of this the technique makes it easier to create different features. It is far more flexible than pouring concrete and being limited by the framework that can be created.

Methods for spraying concrete have been used for over 100 years, which is why Churchill swears by them. There is a great demand for these solutions in the building and construction industry. We are one of the few companies that can provide them to a consistent standard. Sprayed concrete is strong, durable, and is just as reliable as laid.
