Alsip Locating Service is dedicated to providing professional, reliable subsurface locating services throughout the Mid-South. With more than 40 years of combined real-world experience, our team specializes in private utility locating, Ground Penetrating Radar (GPR), concrete scanning, utility mapping, and water leak detection.
Using advanced locating equipment and proven field techniques, we help identify underground utilities and subsurface features before excavation, drilling, construction, and other site work. Our focus is simple: provide accurate information, dependable service, and quality workmanship our customers can trust.
Customer service is at the heart of everything we do. Our experienced team works closely with each client to understand the project, site conditions, and specific locating needs before beginning work.
From private utility locating and Ground Penetrating Radar (GPR) to concrete scanning and pipe locating, we use professional equipment and proven field methods to provide accurate, dependable results. Our knowledge of underground utility systems throughout the Mid-South allows us to help contractors, engineers, property owners, and facility managers make informed decisions before excavation, drilling, cutting, or construction begins.
At Alsip Locating Service, LLC, we use advanced Ground Penetrating Radar (GPR), electromagnetic (EM) locating equipment, and proven field techniques to locate underground utilities and subsurface features.
Our experienced technicians provide private utility locating, concrete scanning, and pipe locating services for commercial, industrial, and residential projects. Depending on site conditions, we can help identify electrical, gas, water, telecommunications, conduits, and other underground infrastructure

Electromagnetic (EM) utility locating is a proven method used to identify and trace buried conductive utilities, including electrical, gas, telecommunications, cable, and metallic water lines. Using specialized transmitters and receivers, our technicians apply or detect an electromagnetic signal associated with the utility, allowing us to trace its approximate location and direction and, when conditions allow, estimate its depth from the surface.
EM locating is an important part of preventing utility strikes and reducing risks associated with excavation, drilling, boring, and construction. By locating and marking underground utilities before work begins, contractors, engineers, property owners, and facility managers can make more informed decisions and reduce the risk of costly damage, project delays, and service interruptions.
Ground Penetrating Radar (GPR) is a non-destructive testing technology used for utility locating and evaluating underground utilities, structures, and other subsurface features. GPR operates by transmitting high-frequency radar signals into the ground and analyzing the reflections generated by changes in subsurface materials and buried objects.
Unlike electromagnetic (EM) locating methods, GPR does not require a utility to be conductive. When site and soil conditions are favorable, Ground Penetrating Radar can assist in identifying or investigating:
Concrete scanning is a non-destructive method used to identify embedded objects and subsurface features within concrete before drilling, coring, cutting, or demolition begins. Using Ground Penetrating Radar (GPR), our technicians can help locate reinforcing steel (rebar), post-tension cables, conduits, electrical lines, voids, and other embedded features.
Knowing what may be beneath the surface before work begins helps contractors and project owners reduce the risk of damaging critical infrastructure, improve jobsite safety, and avoid costly delays or unexpected repairs.
Concrete scanning is commonly used for renovations, structural modifications, utility installations, core drilling, saw cutting, and other projects where knowing the location of embedded objects is critical before penetrating the concrete.
Public utilities are lines and infrastructure owned and maintained by a municipality or utility company. Before excavation begins, contacting 811 allows participating utility operators to mark the approximate location of their underground facilities at no charge to the excavator.
In Tennessee, excavators are required to contact Tennessee 811 before digging and allow the necessary waiting period for affected utility operators to respond..
Private utilities are lines and infrastructure that are owned or maintained by the property owner and are not typically included in a standard 811 locate. These utilities can extend beyond the utility company's ownership or service point and may encompass electrical lines, water lines, gas lines, sewer laterals, communication lines, lighting circuits, irrigation systems, and other privately owned infrastructure.
This is where a professional private utility locating service can assist. Alsip Locating Service uses advanced techniques such as GPR concrete scanning and Ground Penetrating Radar (GPR) to accurately identify private underground utilities before excavation, drilling, boring, or construction begins.
Always make 811 your first call before you dig. When private utilities may be present, Alsip Locating Service can help locate what might fall outside the scope of the public utility locate..

General contractors use Alsip Locating Service to reduce risk and keep construction projects moving safely and efficiently. We locate private underground utilities, perform GPR investigations and concrete scanning, and help identify hidden infrastructure before excavation, drilling, coring, or cutting begins. Our services help prevent utility strikes, costly damage, project delays, and unexpected site conditions.
Engineering firms utilize Alsip Locating Service to obtain reliable subsurface information for planning, design, and construction projects. Our private utility locating, Ground Penetrating Radar (GPR), concrete scanning, and utility mapping services help identify and document existing infrastructure, reduce uncertainty, support accurate project designs, and minimize the risk of utility conflicts, damage, and costly field changes.
Survey companies utilize Alsip Locating Service to help identify and document underground utilities and other subsurface features that cannot be determined through traditional surveying alone. Our private utility locating, GPR, and utility mapping services provide valuable field information that can be incorporated into site surveys, utility maps, and existing-conditions documentation for more complete and accurate project data
Utility contractors utilize Alsip Locating Service to identify existing underground infrastructure before installation, excavation, trenching, boring, or repair work begins. Our private utility locating, GPR, and utility mapping services help prevent utility strikes, verify line locations, reduce costly conflicts and downtime, and provide contractors with greater confidence before breaking ground
Environmental firms utilize Alsip Locating Service to identify underground utilities, storage tanks, buried structures, and other subsurface features before drilling, soil sampling, monitoring-well installation, or site investigation. Our private utility locating and GPR services help improve site safety, reduce the risk of utility strikes, and provide valuable subsurface information for environmental assessments and remediation projects.
