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.
