High-speed scarification is an economical option when job specifications call for removal of less than one-quarter (¼) inch of concrete. Unlike regular hydro-scarification, which is very similar to hydrodemolition, high-speed scarification uses the same Blaster and BlasterVac equipment that we use for rubber removal on runways and paint removal. This machine can also be used for roadways where there is a need to flush the ashpalt.
While our surface cleaning methods (with the same equipment) do not harm concrete, high-speed scarification roughens the concrete to a bondable surface, which exposes the underlying aggregate in the concrete slab. This is achieved by slowing the dwell time(slow the rotation of the water jet and the forward speed of the machine).
Whether we employ a single BlasterVac or a tandem of Blaster truck and vacuum truck depends upon the scale of the project and related factors. The slideshow below shows a variety of images and projects where high-speed scarification was successfully employed.
