If you have to work with asphalt or concrete, you need to have the right equipment to get the job done right. Concrete grinders, shot blasters, floor scrapers, and scarifiers are all used in surface preparation to get different results. So, what is a scarifier, and when should you choose it over other surface preparation equipment?

What Is a Scarifier?

A scarifier is a machine that is equipped with a large drum around which powerful cutting tools are attached in order to create deep cuts and scarring in concrete or asphalt. When the machine is turned on, the drum rotates, turning the cutters at a high speed so they can rapidly chip into the concrete. You may also know it as a surface planer or a milling machine.

Cutters used on a scarifier are typically made from tungsten carbide or hardened steel, and they’re available in a wide variety of widths and diameters as well as number and style of the cutting teeth. Teeth can be flat, sharp, or angled, and each style produces different result and profile.

When Should You Use a Concrete Scarifier?

Before choosing your equipment for a project, you need to think about what the goal of the project is, what kind of surface profile you need, or what the next step following surface preparation is.

When you need a deep, heavily profiled concrete, such as a CSP of 5 or higher, or you need to remove more than one-quarter of an inch layer of concrete or asphalt, a scarifier is generally a good bet. While the profile you achieve will depend on the cutting tool the machine is equipped with, you’ll still get the same general cutting action no matter what.

A scarifier is often used for:

  • Creating a non-slip surface on walkways and sidewalks by adding deep grooves;
  • Leveling misaligned concrete joints and uneven surfaces by removing the top layer;
  • Removing thick floor coverings, such as tile mastics, rubber adhesives, or the thickest epoxy coatings;
  • Removing damaged asphalt or traffic lines from parking lots;

Find the Concrete Scarifier That’s Right for You

If you need to take up old concrete or asphalt to resurface a parking area, sidewalk, or concrete floor, or get a heavy profile in concrete to lay down a thick coating or create a non-slip area, a scarifier is often the best equipment for the job Buy Manufacturers Direct has a wide selection of inventory from small machines to large industrial milling and shaving machines, and we’re happy to help you find the best one for your needs.
