The Combined Power of

Two Leading Excavating Contractors

Two of Central Illinois' top-rated excavating contractors join forces

After successfully building two excavating businesses Issac McCorkle and Sam Nellinger were fortunate to collaborate on several large excavating projects, each leveraging their unique experience and expertise.

Following the successful outcome of these projects, and given the mutual respect they earned for one another while working together, Sam and Isaac decided to join forces, resulting in the establishment of Coal Creek Excavating - now one of the top-rated and most respected excavating companies throughout the area.

Coal Creek Client Reviews

Ben Kovalick

Isaac was great to work with and very professional. He took the time to prep my driveway and remove all the potholes before adding new rock, and graded and compacted it as well. My new driveway looks great and will surely last for years to come.

Dale Morris

Driveway front and back grated, graveled and rolled out. Isaac did a great job and delivered exactly what I asked for. I couldn’t be happier with the result. I will gladly recommend him to anyone who is looking to have work done. Isaac also had previously excavated for foundation work on basement wall and did… Read more “Dale Morris”

Paul Toman

MC Excavating and Drainage did an amazing job refreshing and resurrecting our gravel driveway. Isaac was extremely helpful throughout the process, providing relevant information for any questions we asked. This review was written 3 months after the work was done, and the driveway has held up without issue. Looking forward to working with MC Excavating… Read more “Paul Toman”

Jeff Smith

Sam did great work clearing our future dream home site. It was heavily overgrown but within a day it was walkable, and we could see our vision coming to life much more clearly. I plan to have him back to do more in the future!

Fawn B

Highly recommend Isaac for your excavating needs! I had a smaller space in town that needed drainage, a fence torn out, and gravel. There was not a lot of room for them to work and they nailed it. They got the job done quickly, easy to work with, and very professional.

Ronnie Haiek

I love this company. We have used them multiple times. We’ve had brush removal, dig for a in ground pool and our driveway leveled.

Terry Ruhland

Great work. Fast and fair. You can count on Isaac to get the job done.

Bob Thomas

Sam did a great job! He is professional and personable. He shows up when he says he will and goes over and above to exceed expectations. I highly recommend this company.

Tina Glaspie

Even though I asked for a more inexpensive solution after the first quote, Sam treated me professionally and promptly. The second solution fit perfectly and I will always keep Coal Creek at the top of the list for work I need to have done. TinaG

Jacob Freeman

We needed help with the excavation, backfill and leveling of one of our projects and Isaac and Liberty Excavating helped us out a ton. Even with rain and weather conditions not cooperating in the least bit Isaac kept at it and made it work for us. I greatly appreciate their help and would definitely recommend… Read more “Jacob Freeman”
