Do you need precise ground removal for utility installation, trenching, or potholing? Complete excavation in highly congested underground scopes.
If trench work, boring, or remote excavation needs to be completed in a high-density utility area, then a utility locate must occur. We recommend leveraging Trinity Subsurface for your locating needs as many Call Before You Dig projects leave a 2 ft leniency in their mark outs. Reduce exploratory digging with highly accurate mapping.
We solve the problem of outdated mapping by finding all unknown utilities before exposure. Eliminate guesswork before digging with electromagnetic equipment and ground penetrating radar. Our locating process requires many geophysical tools because we leave no stone unturned!
To excavate, an air lance is used to loosen the ground while the soil is sucked up by a vacuum. For harder materials such as compact clay, the vac truck will leverage high-pressure water. The paradigm system of the truck allows field employees to use both methods on the same job site!
The area is cleared to appropriate depth or a utility pipe is uncovered, requiring manual operation. Using trenching and boring techniques, place with precision:
Field employees document found utilities, subsurface data, or anomalies while trenching. Our reporting platform makes it simple for data to be recorded the same day.
With air excavation, remove large amounts of soil, soft clay, or shale that can later be redeposited. Soil can be left on-site to be refilled at a later time after line installment.
Within a test hole report, underground features found during trenching or remote excavation are observed and documented with precision.
Preliminary step: locate utilities, foreign objects before digging.
Trinity Subsurface, LLC will protect your work zone with temporary traffic control while conducting excavation services for commercial sites, municipalities, and residential areas.
Air excavation is the process of using compressed air to disturb the earth’s soil. The soil is vacuumed through a wide, flexible hose to a truck-mounted debris tank. The tank can be parked remotely, up to a hundred feet from the dig site, to minimize congestion and additional surface damage. Air excavation is used to safely expose underground utilities and allows backfill with the dry material.
Hydro excavation is a non-mechanical, non-destructive process that combines pressurized water and a high flow of moving air to simultaneously excavate and evacuate soil and natural debris at a controlled rate. The soil and water slurry travels through a hose to a debris tank. Hydro excavation allows for the breakdown of clay and rocky soils.
Trenches are cut to various dimensions with great accuracy and precision using high-pressure water or air. It’s an effective method when searching for utility lines especially when the location is unknown.
Slot trenching is a method used for installing pipes, sprinkler systems, cables, signs, posts, and other utilities underground. The method is also used for narrow trenching around the perimeter of a foundation, for the installation of grounding wires, or electrical lines.
Easier access to areas where backhoes or larger excavation may not fit. Less destructive to surrounding landscape. Also to cut out specific dimensions such as "L" shaped trenches or cylindrical pits for piers, pylons, or sono-tubes. Spoils can be either transported immediately, left on site at specific locations or put back into the excavation area. Plus the big one, no damage to unmarked utilities. Capable of doing large dimensions or small test holes.
Yes, we sure do! For any work sites where we break asphalt such as state highways, our field employees will conduct patch repair with the Core Bore Process.
Some benefits of the Core Bore Process include:
- A permanent repair
- Overall process (repair and restoration) time reduced
- Less time to excavate roadway surface and base
- Less inconvenience to vehicular traffic during work
