Client Reviews

Geohazard Services for Roads in Maryland

Thank you for your work efforts on Madonna Road (& Ridge Road). As always, your crews were professional, worked hard and kept us informed of what they were doing…. We hope that we never have to bring you back to Harford County (I trust you understand that statement ☺), but are very comfortable in the knowledge that if we do ever need your expertise again in the future, that you will be ready and willing to help and your staff will continue to perform the work exceedingly well.

Transformative Project for Homeowner in Minnesota

Just wanted to say that somehow your workers/artists took an ugly and scarred piece of this earth and turned it into a very pleasing and contoured piece of this earth. It looks incredible!! The fellows were all so nice and just wonderful to us. They worked so hard and were always hear early…….no goofing off…. just working. My husband suffered a traumatic brain injury in early 2012 and it has been a rough couple of years. He is almost completely healed. There were many tears and a lot of frustration. Seeing this project and the amazing workmanship put into it has really put a smile on our face. We thank your fathers for getting this company up and running. We thank you and Tim for keeping it running. Your company made a difference in our life and one we will not soon forget. It is easy to say thanks…it is hard to put into words.... but know that our thank you comes from the heart!!!

Emergency Rockfall Mitigation for Mining Operations

I recently interacted with some of your rockfall division guys. I have never seen an outfit as competent on safety measures nor any contractors who worked as hard as your guys do. During the work, I was in a room with your guys and some other contractors, and your guys were head and shoulders above the rest in all aspects.
