Underground utility mapping/utility detection, which is also known as utility locating, requires the application of advanced and high-tech equipment to create an extremely detailed map of what is going on beneath the surface. Instead of risking damage to the numerous pipes and cables present underground, a service of utility locating in San Francisco or any other location is able to verify existing infrastructure and practice safe excavation methods.
Here are some of the most common misconceptions that people have with regards to underground utility locating.
One Call (811) will mark out all the underground utilities: One Call generally marks only the public parts of the underground utilities. There can be times when electrical power, natural gas lines, and telecommunication can be marked from the street to your own property, but in an usual scenario, that does not take place for water, storm drain, and sanitary sewer utilities.
Private utility locating services will mark out all the underground utilities: Even though private utility locating services will try to fulfill your requirements to mark all the important or relevant utilities, the locating technologies which also include the Ground Penetrating Radar (GPR) can have limitations. There are usually no grantees present who can confirm if all the utilities are located. You may still be required to go ahead with full caution for any ground-intrusive work left.
GPRs can see all underground utilities: This is not true as even the most advanced machinery comes with its own limitations. So, it is advisable not to believe in such fake promises.
