L & N Zimmerman Excavating Inc. is a Southeastern Pennsylvania contractor based in Myerstown, PA. Our primary focus is on the underground trenchless industry, including horizontal directional drilling, auger boring, and hydro excavation.
We use trenchless technology to install utility lines such as sewer, water, gas, electric and communication, minimizing impacts to travel, infrastructure and the environment.
We serve utility contractors, municipalities, commercial and residential clients as well as agriculture projects. Our regional focus is primarily the eastern third of Pennsylvania, Northern Maryland, and Northern Delaware.
Directional Drilling, or Horizontal Directional Drilling (HDD), is a technology that has been evolving since the 1970's. Directional Drilling can be used effectively in many situations where conventional trenchless methods will not work.
Auger boring is a technique used extensively for trenchless installation. The technique consists of jacking the casing through the ground while a cutting head and flighted auger assembly remove the spoils from the face.
Hydro excavation is the process of removing or moving soil with pressurized water. This method reduces risks for any damages or punctures to existing underground pipes that convey electric, water and gas to our surrounding communities.
