Simple, cost-effective Surface preparation
Floor scarifiers (also known as concrete milling machines and concrete planers) use cutters attached to a rotating drum to chip away at the top layer of a concrete, asphalt or steel surface.
Floor scarifiers dig deeper into the surface than some other machines (e.g., floor grinders) and leave distinct grooves behind. Their aggressiveness makes them useful for a range of surface-preparation projects. These include removing lines and overlays, eliminating trip hazards and creating a concrete surface profile (CSP) ranging from 6 to 10 (medium-rough to extremely rough).
Husqvarna floor scarifiers are cost-effective, easy to use and simple to maintain. They come in a variety of working widths and power sources (petrol, corded electric and battery). You’ll find them wherever surfaces need to be repaired, textured or levelled: bridges, roads, warehouses, parking-garages, sidewalks and driveways.
How do husqvarna floor Scarifiers work?
Watch this animated video to see how our floor scarifying machines efficiently prepare concrete, asphalt and steel surfaces.
The machines are equipped with cutters that are loosely fitted on lateral shafts inside a drum. When the machines are switched on, the drum rotates and the cutters hammer away at the surface, removing the top layer and leaving the surface textured with grooves.
All Husqvarna scarifiers are equipped with a precise height adjustment system for adjusting the working depth. Dust and contaminants created by the scarifier are removed by a matching Husqvarna dust extractor.
The benefits of floor scarifying
Cost-effective
Floor scarifying is a cost-effective way to prepare surfaces thanks to the low cost and long life of carbide cutters. The method makes it easy for operators of all skill levels to cover surfaces quickly and achieve professional results.
Versatile
Floor scarifying may be the best choice for surface-preparation jobs requiring deep cuts, thick coating removal or levelling uneven surfaces.
Efficient dust pickup
When a floor scarifier is connected to the appropriate dust extractor, dust is captured as it is created.
Choose the right cutting tools
Cutting tools are not all the same. The carbide cutters you choose can impact your scarifier’s performance, the results you get and your bottom line.
For effective scarifying, Husqvarna carbide cutters are designed with six points rather than the market standard of five. Our Elite-Cutter™ tools also have extra long and thick carbide tips, which significantly extend the tools’ life – making them an excellent investment when tools need to last from one job to the next.
The placement of the tools on the drum shaft also matters. Many drums have a middle flange that creates a gap between cutters, leading to an inconsistent scarifying pattern. Because Husqvarna CP scarifiers have no middle flange, operators of all skill levels can easily get consistent, professional results.
Concrete surface profiles (CSP)
The profile left behind on the surface when scarifying depends on the working depth of the drum and the speed of the machine. Scarifying allows you to achieve a concrete surface profile between 6 and 10 (set by ICRI – International concrete restoration institute). See the chart for more guidance.
| Surface Profile | CSP-3 | CSP-4 | CSP-5 | CSP-6 | CSP-7 |
|---|---|---|---|---|---|
| Method | Heavy grinding or very light shot blasting |
Light shot blasting | Medium shot blasting | Medium / heavy shot blasting or light scarifying |
Heavy shot blasting or medium scarifying |
| Hardware | To achieve CSP-3, use a Husqvarna grinder with PCD tools or use a Blastrac shot blaster with small sized steel shot at maximum speed. |
To achieve CSP-4, use a Blastrac shot blaster with small / medium sized steel shot at high speed. |
To achieve CSP-5, use a Blastrac shot blaster with medium sized steel shot at medium speed |
To achieve CSP-6, use a Blastrac shot blaster with medium / larged sized steel shot at medium speed or a Blastrac scarifier at low depth |
To achieve CSP-7, use a Blastrac shot blaster with large sized steel shot at low speed or a Blastrac scarifier at medium depth. |
