Serving Industrial, Commercial, and Municipal Clients

We provide a full range of excavating and construction services for industrial, commercial, and municipal clients throughout the northern Illinois region. With our skilled workforce, top of the line equipment, emphasis on safety, and attention to detail, we can make your project a success.

General Contracting

With safety being our number one priority, Conley Excavating & Construction can encompass everything related to your project from excavation, sewer and water, to industrial and commercial concrete work. We can set deadlines and budgets, coordinate with specialty subcontractors, manage employees, and obtain appropriate building materials. We can also manage stakeholder expectations, acquire needed permits, and ensure every part of the project is up to code and meets your expectations.

Concrete Construction

Our highly skilled labor force provides industrial concrete services including but not limited to foundations and supports, flatwork, and concrete restoration. We ensure our work is of the highest quality with an emphasis on safety combined with a timely completion while working diligently to find solutions and overcome any challenges that may arise in an industrial setting.

Vactor Services

Our Vactor 2100 combination truck provides various services not only for our own forces which ensures the safe location of underground utilities but also for other contractors and industrial and municipal clients needing similar services or maintenance such as cleaning basins and manholes. Our truck has the ability to rod up to 600 feet of sewer line and also performs hydro-excavation for a safer excavation alternative.


Utility Services

With miles of pipe successfully installed throughout northern Illinois, we have built a strong reputation with the municipalities and communities in which we work. We have been continually commended for our well-coordinated logistics and clean construction sites. We fully understand the patience required of the community impacted by these projects which is why we make it our goal to maintain a high level of communication with homeowners and respect their property as we do our own.

General Site Excavating

We provide site preparation for commercial and industrial sites including earth excavation, placement, grading, and compacting as well as aggregate installation. Our skilled operators have been trained to pay close attention to detail and use the latest GPS technology to ensure our site work is within the tolerances needed for any project.  We deliver a choice finished product that exceeds your expectations.

Service Repairs

Utility breaks and leaks pop up when least expected. Our various sizes of excavators, trailers, and trucks fully equipped with all necessary tools and safety accessories allow us to quickly mobilize to any repair in short notice to solve the problem as quickly as possible.


We provide demolition services for industrial, commercial, and municipal projects. We work closely with consultants to perform hazardous testing if needed to ensure the construction site is property remediated prior to the commencement of demo operations. Our priority is to make sure all debris is removed appropriately and the site is cleaned thoroughly so there is no remaining evidence of the previously existing structure.

Manhole Restoration

We are well equipped to perform this specialty task. We provide external restoration services, corbel repairs, ring replacements, frame replacements, and seal installation. Additionally, we have the ability to spray internal cementitious coatings.

Directional Boring

Directional Boring or Horizontal Directional Drilling (HDD) is a technology for installing conduit, pipeline, telecom, and fiber without the need of digging an open trench. Conley Excavating and Construction has access to the latest in directional boring technology and can install pipeline and conduit up to 6-inch diameter to support water, gas, sewer, electrical, and telecommunications applications.
