New Sawtec scarifiers featuring heavier frames and drums are ideal for repairing common slab problems: curled joints, high spots, uneven slabs, burned slabs due to overtroweling, trowel marks and damage due to weather. A variety of cutter teeth and quickchanging drums allow for easy reconfiguration to meet a range of applications — from light cleaning to heavy coating or laitance removal. For greater control and easier handling, Sawtec scarifiers include a quick lift-off feature and micro-depth control for fine-tuning the cutting depth. Gas or electric scarifiers are available in sizes from 8" to 13" widths. Sawtec scarifiers remove oil, contaminants, traffic lines, epoxy coatings or paint from asphalt and concrete surfaces. They are also suitable for smoothing uneven surfaces and trip hazards, or for cutting safety grooves in ramps, walkways and loading docks.
