Grit Blasting Concrete.
Concrete Shot blasting Sandblasting concrete also known as concrete shot blasting or concrete grit blasting is a common practice used for aggregate exposure, to achieve a slip rating on pavements , to create a anchor point for coatings to adhere to or to remove a coating. Concrete grit blasting can be performed with both traditional dry sandblasting and wet or dustless sandblasting technologies. When performing onsite concrete sandblasting works there are a few things that need to be done to ensure safe and smooth operations - Creating an appropriate exclusion zone prohibiting the entry of unauthorized personnel. - Protecting adjacent surfaces from over blast - Ensure all appropriate PPE is being worn - If working in enclosed areas ensure sufficient ventilation - If necessary wet blasting technologies and full contamination must be utilised - Never allow untrained personnel to operate grit blasting equipment The level of sandblasting required will always be discussed with the client before completion of the job, a test panel will be produced to ensure client satisfaction! Concrete blasting for exposed aggregate is Generally completed in 3 different levels:
- Light blast: a light blast is chosen in areas where a slip rating is required (generally p4 rating) to comply with relevant Australian slip rating standards. A light blast generally offers a small amount of aggregate exposure.
- Medium blast: a medium blast offers the same slip rating as a light blast however it exposes more aggregate.
- Heavy blast: as the name suggests a heavy blast is the type of blast offering the largest amount of aggregate exposure and consistency whilst keeping up with the relevant slip rating standards, for these reasons above the heavy blast is the most commonly chose finish when shot blasting concrete. Sandblasting concrete surface is a very common practice used in parks, warehouses, shopping centres and more. Contact us for your free quote today.
