Line markings on asphalt surfaces can be similarly removed using the captive blasting technique, preserving the integrity of the underlying asphalt surface structure.

Cleaning & Removal of Surface Contaminants

Cleaning & removal of surface contaminants is a common task on concrete and asphalt surfaces and is primarily achieved using dust free, environmentally friendly captive shot blasting techniques. A keyed surface also results for the application of thick coatings if required.

Surface Levelling / Removal of High Spots

Surface levelling / removal of high spots on concrete surfaces can be achieved using surface planing techniques. This can often be quicker and more cost effective than using more complex levelling compounds. In cases where significant depths of concrete need to be removed, cold planing (or milling) becomes the surface preparation technique of choice, leaving a keyed surface with anti-skid properties that can be used as a temporary highway. In certain circumstances where a greater degree of control is needed for the desired finish, surface grinding may be employed. This is more common on walkways and in pedestrianised areas.

Surface Re-Texturing

Surface re-texturing using captive shot blasting techniques is a process where small steel shot is propelled at speed onto the asphalt surface,removing deeply embedded surface contaminants, dirt and grit. This dust free,environmentally friendly process restores the asphalt surface texture without damaging the surface structure with speed and efficiency.

Deep Asphalt & Concrete Removal

Asphalt & concrete removal to much greater depths is often required when a complete, new flexible / asphalt surface is to be reapplied on roads and highways. Cold Planing (or Milling) is the primary method of choice in such tasks, eliminating the need for complex levelling courses whilst leaving a highly skid resistant surface that can be used by traffic until the new surface can be applied.
