ELECTROMAGNETIC

Electromagnetic locators allow us to find conductive utilities such as phone, electric, & water. Our receivers pick up the metallic body below the ground, then its position and orientation is marked on the surface per CGA and APWA standards.
Utilities with a conductive "tracer" such as fiber optic and gas can also be located using this method.
For sewer main lines and laterals we utilize a CCTV push camera equipped with a Sonde (radio transmitter) for locating. The sonde is inserted into the sewer lines or adjacent lateral lines and the signal produced can be picked up from above ground.
These methods allow for the the majority of utilities to be located quickly and with out hassle. For those tricky environments and / or  where more detailed data is needed we have a solution using our GPR and CCTV services, see below...
Even in the most complex environments, Ground Penetrating Radar is perfect for sorting out what you're working with down there.
 We use the Quantum Imager GPR, a tri-band antenna transceiver that can find underground objects from 1’ to 30’deep simultaneously.
Tri-band tech provides the highest resolution imaging available on the market.
Non-conductive utilities like fiber optics & pvc lines or utilities without a tracer can be allusive. However GPR can easily locate and map these utilities.
 
​GPR is a safe and fast method used for concrete scanning to locating re-bar, conduit, pipes and other objects within a concrete slab prior to cutting, coring or drilling.
Spearhead Locating Services operates state of the art CCTV IBAK sewer inspection equipment with lateral launch capabilities.
We are your certified source for all PACP, LACP, and MACP inspections.
Our IBAK crawler tech is also perfect for pre and post inspection of sewer laterals and storm drains.
Our mainline crawler can inspect and document 1000ft  of 6" to 48" pipe.  With the crawlers lateral launch capability we can inspect up to 100ft of 4"(min) lateral lines.  The on board sonde transmitter allows for precise survey locating.
During inspection, a high-res full color video can be viewed and recorded. Details of the inspection such as root intrusion, structural damage, pipe offsets, and flow can be documented using NASSCO certified Pipelogic software.
