We had a great time sponsoring the Baltimore Power Group's May luncheon at Jimmy's Seafood! 🦀

It was a pleasure connecting with property managers across the region and talking about what we do best — parking lot resurfacing, road paving, patching, and repairs that keep commercial properties looking and performing their best.

Thank you to the Baltimore Power Group for having us. If you manage properties and need a paving partner you can count on, we'd love to connect.

What a day on the course! ⛳☀️

Gradeline Construction was a proud sponsor of the 2nd Annual Golf Tournament, co-hosted by the Maryland Asphalt Association and Maryland Women of Asphalt. Cory Freeman and Debi Freeman repped Gradeline, and Debi brought home the Women's Closest-to-the-Pin award! 🏆 So proud of you, Debi!

130 golfers enjoyed perfect weather, great competition, and even better company. Thank you to the MAA and MD WofA for putting on a first-class event. See you next year!

🌙 When the sun goes down, Gradeline gets to work.

Some of our most important jobs happen after hours, and our Roadtec RX600 milling machine doesn't care what time it is.

Earlier this winter, we completed trench patching along a utility corridor where a new gas line had been installed. Now that nighttime temps are consistently holding above 50°F, we're back to finish the job right. Milling out 1.5 inches of existing asphalt and laying a fresh surface overlay.

That's the Gradeline process: we don't just patch and move on. We come back, we mill it clean, and we pave it properly.

✅ Nighttime operations
✅ Milling & surface overlay
✅ Utility trench restoration
✅ Baltimore-Washington Region

Got a project that needs to happen after hours or can't wait for warm-weather scheduling? Give us a call. 📞

That pothole didn't appear out of nowhere. Winter weather is one of the leading causes of pavement failure and most property managers don't catch the warning signs until the damage gets costly. Gradeline General Manager Mike Harp answers the questions we hear most this time of year. Read the full Q&A on our blog. 👇

🚛 New iron on the job. Meet the latest additions to the Gradeline fleet — a 2026 Mack Granite GR84F rolloff truck and a 2026 Landoll 440B 40-ton traveling axle trailer.

The rolloff handles the heavy stuff: trash, broken concrete, asphalt, and millings. The Landoll moves our milling machines, pavers, and skid steers where they need to be.

More muscle. More capability. Same crew you trust. Give us a call! https://gradeline.com/contact-us/

Winter was rough on our roads and parking lots this year, and not all of the damage is visible from the surface. 🚧

When snow and ice aren't cleared quickly, they compact into any weak spots in the pavement. Add extreme cold temperatures on top of that and water starts working its way into cracks, freezing, expanding, and pushing deeper into the base layer. By the time you see a major problem, it's often been building for a while underneath.

We sat down with our General Manager Mike Harp to talk about what this winter really did to pavement in our region and what property owners and managers should be doing about it now that spring is here.

🥾 It's Annual Shoe Mobile Day at Gradeline! 🥾

Every year, the Saf-Gard Safety Shoe Mobile pulls up to our yard. A full shoe store on wheels, right here on site, just for our crew.

Every Gradeline employee got fitted for brand new work boots. Saf-Gard's shoe experts came to us and made sure every person walked away with the right fit for the work they do. Choices included composite toe, steel toe, oil & slip resistant soles, high-heat soles (for standing on asphalt! 🔥), waterproofing, electrical hazard protection, and cushioned insoles for those long days on their feet.

Our people work hard and they deserve the right gear to do it safely and comfortably. This is just one of the ways we invest in the team that makes Gradeline.

Big thanks to -Gard Safety Shoe Company for making it easy and bringing the store to us! 🙌

It’s Women in Construction Week and we couldn’t let it pass without shouting out the amazing women holding things down in our office! 🙌

From keeping projects on track to making sure our crews have what they need — these women are the backbone of Gradeline Construction. Detail-oriented, driven, and always showing up.

We are so grateful for you!
