Blastrac scarifiers are versatile, dust-free surface preparation tools used for concrete, asphalt and even steel surfaces. Scarifiers use steel or carbide tipped cutters, in various shapes, depending on application, that are loaded on shafts placed around the perimeter of a cylindrical drum. As the drum rotates, the cutters impact the surface at a high speed, fracturing the coating and/or contaminants and abrading the concrete surface.
Use scarifiers for repairing common slab problems, such as:
- curled joints or high spots
- trowel marks or uneven slabs,
- burned slabs due to over-troweling
- damage due to weather
Blastrac scarifiers remove oil, contaminants, traffic lines, epoxy coatings or paint. They are suitable for smoothing uneven surfaces and trip hazards, or for cutting safety grooves in ramps, walkways and loading docks.
