Frequently Asked Questions
Optimal conditions for utilizing GPR are as follows:
Turn off all sprinkler systems at least 24 hours in advance. We recommend 72 hours. Ground saturation due to rain, running, or standing water will interfere with the equipment.
The job site must be clear of all debris. GPR works best on flat, smooth surfaces such as dirt, concrete, grass, etc. Please note that tire ruts, back hoeing, tall grass, and excessive presence of boulders will hinder the process.
GPR is ideal for locating water lines, sewer lines, septic tanks, as well as any large obstructions that may be buried under the job site.
The electromagnatic transmitter and reciever is ideal for all your conductive locating needs. Most residential properties opting to install a new pool or fence will require a private locate to understand where the utlities fall in their backyards to avoid costly damages and outages in service:
Private electrical lines
Private gas lines
Cable and Communications
All of our locates are valid and insured for two weeks. If your project is delayed we recommend rescheduling a revisit to ensure that the markings are accurate and visible.
Please note the the industry standard is to clear a minimum of eighteen (18) inches on each side of any given marking. The assigned technician will indicate if a larger margin for error is necessary at the time of the locate based on the nature of your project.
Property owners digging in their yards are responsible for locating underground electric service drops and natural gas house lines on private residential or commercial property before digging.
A private service drop is an electric line running from a building to the energy provider's electric distribution lines. Private service drops are the responsibility of the property owner and will not be located, identified or staked by most service providers.
A house service line is a natural gas line running from a building to the meter. This part of the gas line is the responsibility of the property owner and will not be located, identified, or staked by most service providers.
A gas service line leads from the meter to the service provider's main gas lines. Gas service lines are the responsibility of the service provider and will be located, identified, and staked accordingly.
The Universal One Call system is a fee based universal dispatch system that is set up to locate all utilities, both public and private, using the benefits of the Texas One Call System and the follow up of our own professional utility locating technicians. Locate orders are issued for the utilities managed by private companies as well as the public utility lines. Any lines not under the Texas One Call are then located by our in house staff. Verification is then made on site to insure that all utilities are properly identified and excavation crews are notified to proceed.
Additional support is available for any questions covering utility location or depth on site. Once on site they identify all utilities at one time. There is also direct contact with the excavator and follow up to insure that any questions about digging are resolved. This drasticly reduces the risk of damage, interuption of service, and risk of fire or other loss.
The Universal Dispatch Center monitors all locates and scheduled excavations. The system is set up to incorporate multiple work sites using different contractors with different dig dates.
The Texas One Call system is a no charge, centralized dispatch center that is set up to identify and locate primary utility services up to the private property meter and must be used for excavations taking place within 48 hours of excavation. Locate orders are sent to each public utility company for their technicians to initiate a locate request, however there is no follow up to insure that all orders have been executed.
There is also no program in place to make sure all utilitites are located. Many times the excavator may start to dig before all the utilities are identified, causing damage, loss of utilities, and even risk of fire or other loss. There are several types of privately owned utilities that are often missed by the Texas One Call system. These utilities include the following: high pressure gas and communication lines, private fiber optic lines, private illumination, fire mains and sprinklers, and leased out cable casements and culverts.
