Mason's 5-Step Process to Locate your utilities
Public, Private, & the Unknown
Many underground facilities and structures are not marked by the 811 system. Our technicians a 5 step process to ensure your job site is marked with complete accuracy.
Step 1: Site Walk
Visual Site Scan
An MPL Project Manager takes the time to visually inspect the project site while looking at any maps or prior documentation to identify the known utilities.
Step 2: Find & Verify
the Known Utilities
EM Receiver / Transmitter
We locate the known private utilities with surface level indicators (valves, meters, etc.) such as electric, gas and water lines that continue beyond the meter. During this step, we can verify known public utilities.
- Communication Lines
- Electric Lines
- Abandoned Utilities
Step 3: Find & Identify
Unknown Utilities
EM Passive & Induction Scans
Next we locate any unknown utilities that do not have surface indicators, such as communication lines (including fiber) running between multiple buildings. In many cases, abandoned utilities are also found during this step.
- Underground Storage Tanks (UST)
- Non-Metallic Utilities
- Unknown Utilities
STEP 4: Find Anomalies Underground
Ground Penetrating Radar (GPR)
In this important step, MPL utilizes GPR on every job to find any additional unknown objects in the area such as non-metallic pipes, large storage tanks, plastic water mains. GPR is also used to verify our own marks during the EM process (Step 2) of our locate.
- Plastic Pipes
- Storage Tanks
- Fuel Tanks
- Unmarked Steam Lines
Step 5: A Peace of Mind
A SECURE JOB SITE
MPL's Project Manager documents all findings from each step and creates industry leading deliverables so you have full visibility and understanding of everything that was located on your job site.

LOCATE, INSPECT, SURVEY
& MITIGATE RISK
No Second Guessing
Due to size, depth and access, sewer mains and laterals are rarely located during the 811 process. In addition, many contractors and engineers often need Sewer Inspection and Cross-bore mitigation services to confirm any hidden dangers or liabilities in these lines. Common finds are cross-bores, sewer line cracks, infractions, blockages, etc.
- Locate Sewers & Possible Blockages
- Identify Cross-bores
- Identify Cracks and Future Issues
