Asphalt surfaces like parking lots and roads require vigilant maintenance to maximize lifespan and reduce costs.

While asphalt repairs are sometimes unavoidable, regular upkeep helps delay major projects and repairs. One crucial and often overlooked aspect?

Timely and effective crack cleaning and sealing.

This is where crack cleaning machines can make a real difference for the health of your asphalt infrastructure.

In this guide, we'll cover the ins and outs of crack cleaning machines. You'll learn their key benefits, important features, proper usage, and whether renting or owning is best for your needs. We'll also debunk common myths and answer frequently asked questions from asphalt maintenance professionals like you. Let's pave the way to a smoother, safer, and more cost-effective asphalt maintenance program.

What are Crack Cleaning Machines and Why Do You Need One?

Crack cleaning machines are powerful tools designed specifically for cleaning out cracks and joints in asphalt surfaces. They utilize water, heat, air pressure, or a combination to remove debris, weeds, old filler material and prepare the crack for new filler or sealant.

Proactive crack cleaning and sealing is crucial for extending the lifespan of any asphalt surface. When cracks are left unfilled, they allow water to seep in and cause further deterioration of the pavement through freeze-thaw cycles. More damage leads to larger repairs and eventually full asphalt replacement. Not ideal for your budget or sanity!

Crack cleaning machines allow you to clean cracks thoroughly prior to using the right sealant or filler. This ensures maximum adherence and prevention of water infiltration. Consistent crack maintenance also stops small cracks from expanding into major headaches. Ultimately, investing in the right cleaning equipment saves you money over time.

The Power of Proper Crack Cleaning

Crack cleaning machines are powerful partners for effective asphalt maintenance programs. Here's how they contribute:

Crack Repair Quality

Thorough crack cleaning allows sealants, fillers and other treatments to adhere optimally. When cracks are cleared of old material, weeds and debris, there is greater bonding between the repair products and crack edges. No contaminants means no weak points for water intrusion or issues down the road.

Preventing Further Deterioration

Keeping cracks sealed means water can't enter the asphalt substrate, especially during winter. This prevents formation of potholes, sinking, raveling and other deterioration caused by water damage. Consistent sealing maintains your asphalt's structural integrity.

Extending Asphalt Lifespan

With routine cleaning and sealing, you can get decades more life from your asphalt investment. Your parking lots, driveways and roads will look better and perform better longer, saving you money. It's a win-win for aesthetics and your wallet.

Choosing the Right Crack Cleaning Machine

With the right asphalt crack cleaner machine, you can optimize asphalt maintenance and surface preparation based on your specific needs. Here are key considerations when selecting equipment:

Crack Width Capabilities

Crack sizes dictate the best cleaning method. For high pressure water power, look for machines that can handle cracks from 1⁄4 inch to 2 inches wide. For heat lancing, needed for larger cracks, choose equipment with heating wands up to 3 inches wide.

Power Source

Gas-powered crack cleaners like the Billy Goat Grazor or RynoWorx Hedgehog allow for mobile use not dependent on electrical outlets. Electric crack cleaners offer quieter operation and less emissions. Look for ample power and pressure levels for your cleaning needs.

Brush Types

Steel wire brushes thoroughly loosen debris in cracks while nylon brushes provide gentler cleaning. Machines with adjustable brushes or multiple brush options add customization ability.

Adjustable Settings

Variable water pressure, heat and vacuum power gives you more control over the cleaning process. Look for units with settings that match your typical crack sizes and debris levels.


For cleaning large areas, opt for wheel-mounted machines with large water tanks and attached hoses and wands. Handheld units provide versatility for small jobs.
