Blasted
A grit (or sand) blasted finish is typically a rougher and deeper-textured finish than an etched finish. With this finish, the surface layer of concrete is removed to expose the aggregate (stone) in the concrete mix.
The depth of the blasting can be varied to allow a smooth to coarse texture. The aggregate selection, as well as the matrix colour, has a significant effect on the final appearance.
The finish is achieved using a technique using compressed air to propel various particles (e.g. granulated furnace slag, aluminium oxide, glass beads) onto the concrete surface. The process is also referred to bead blasting where larger beads are used.
Note
Concrete is made from natural raw material, so while we take care to ensure you achieve the desired outcome, expect aggregate and colour variations and imperfections in precast.
Photos and samples are an indication only and can vary in colour, shape and texture, there is no guarantee that your precast project will look exactly like the sample that you have viewed.
Architects and builders, please be aware that minor patching/repairs may be required due to handling, transportation and installation- these are likely to be noticeable.
