When looks matter, your drill bit size matters too.

If you’re in the concrete lifting business and always drilling 5/8” holes—or larger—you’re probably losing out on jobs and don’t even know it. For property owners who care about the appearance of their concrete, especially those with stamped or decorative surfaces, those big holes are a deal-breaker.

That’s where the 3/8″ polyurethane drill bit comes in. It might sound like a small difference, but it makes a big visual impact—and it’s one of the easiest ways to gain a competitive edge.

Why Drill Bit Size Can Make or Break the Job

Think about this from the buyer’s perspective. If someone lives in a high-end neighborhood or has decorative stamped concrete on their front walkway, they don’t want big scars left behind. They want it to look as close to untouched as possible. When you show up and explain that your system uses a small 3/8″ drill bit and that you’ll patch everything neatly, they feel confident in your solution. You’re adding value.

Compare that to the guy who says “we’ll just patch the big holes after”—that homeowner is left wondering if their driveway will look like it has chickenpox.

3/8” vs 5/8”:

• 3/8” Polyurethane Drill Bit: Easier to hide between grout lines on stamped concrete. Less noticeable even before patching. Gives a cleaner, more professional appearance. Ideal for high-end homes.
• 5/8” or Larger (Common): Leaves bigger, more visible scars. Harder to patch cleanly. Less ideal when aesthetics are a priority.
• Mudjacking – Those are going to be much bigger holes than poly. Make sure your customer is aware. This is about positioning you as their best option.

Sell the Invisible Fix

In marketing, it’s all about knowing your buyer persona—and when the buyer is someone focused on looks, your drill bit size becomes a selling point.

Make it part of your pitch. Tell them:

• You use small, 3/8” holes that hide in grout lines whenever possible
• You patch all holes cleanly and aim to leave the surface looking as untouched as possible – nearly invisible
• Your solution gives them both safety and beauty

Because at the end of the day, they want to solve the problem—but they don’t want their concrete to look worse after you’re done.

This Is About Trust and Professionalism

Small details like drill bit size are what separate pros from fly-by-night lifters. Homeowners and commercial buyers alike want someone who:

• Knows what matters to them
• Explains the process clearly
• Uses the right equipment for the job

When you take pride in the small things—like neat holes and clean patches—it reflects your pride in the big things too: doing great work, offering honest pricing, and being someone people trust around their home or building.

Don’t Let the Other Guys Win on Looks

Most concrete lifting companies talk about foam strength and lifting speed (which matter)—but overlook the customer’s emotional concerns. Most people care just as much about how it looks when it’s done.

So if you can confidently say, “We use smaller 3/8-inch drill bits and aim for invisible repairs,” you’ve just out-positioned the competition in a big way.

They get safety, function, and aesthetics—all in one solution.

Final Thoughts

In this business, perception is reality. Small holes don’t just mean a cleaner look—they mean more trust, more calls, and more jobs won. If you’re not talking about this yet on your website or in your bids, you’re missing a powerful angle that could be the deciding factor for your next client.

Start mentioning your 3/8” drill bits. Show photos. Explain why it matters. And make it part of your brand promise: to lift concrete without leaving a mess behind.
