An Introduction to Grit Blasting
There are so many different types of concrete work and varieties of ways to restore buildings with concrete that it can be hard to know which technique is best for your project. However, here at Concrete Renovations, we are industry experts with a wealth of experience. This means that after careful research and consideration, we will always ensure the right approach is taken to each individual concrete repair project based entirely on its own merits.
However, at the same time, we think that it is important for our clients to understand the work we do. That way, you will be able to rest assured in the knowledge that we are taking the very best approach to your project. With Concrete Renovations, your concrete repairs are guaranteed to be in safe hands.
Grit Blasting & Concrete Repairs
So, to start at the beginning, before you commence the concrete repairs themselves, you must make sure everything is ready and prepare the applicable area for the work that is about to take place. One of the ways that we can do this is by a process called grit blasting.
We offer grit blasting to prepare stone, concrete and masonry for the next stage of the restoration process. If necessary, we also provide grit blasting services to clean reinforced steel prior to repair.
So what exactly is grit blasting?
Grit blasting - also known as abrasive blasting - is basically where you propel a concentrated stream of abrasive media onto a surface to smooth, shape, roughen, or remove surface contaminants. There are a number of variants to the process, each with their own individual set of benefits, making them suited to different projects respectively.
Wet abrasive blasting
Originally developed as an alternative to sandblasting, wet abrasive blasting is a multi-purpose, fairly adaptable method of grit blasting. It allows you the freedom to use media ranging from coarse to super fine materials, including a variety of different densities. It can also be used to eliminate dust, so hazardous waste materials such as asbestos can be easily removed without any danger.
This variation of grit blasting removes build-ups on the surface by driving small glass beads against the surface. It is very useful as it removes unwanted build-ups but avoids damaging the actual surface underneath. This makes it ideal for cleaning pool tiles, grout, vehicle bodywork, and removing embedded fungus.
In this technique, a wheel pushes the abrasive media against the object that requires cleaning by using centrifugal force. It is a high efficiency and high power operation, but the abrasive is recyclable.
This is one of the more common
This process directs a small stream of abrasive material to a specifically targeted area. It is normally used for smaller, delicate operations but can also be used to write on surfaces such as glass.
Dry ice blasting
This technique dislodges surface contaminants by frozen particles of carbon dioxide drumming against the surface at a high velocity. It is useful as the dry ice leaves no residue, vastly speeding up the clean-up process.
Different to other methods, bristle blasting doesn’t use separate media. Repeatedly using the brush against the surface both cleans and coarsens the surface at the same time.
