HYDRO JETTING / FLUSHING

Hydro jetting is a method used by professional plumbing contractors to clean clogged or slow sewage lines. A blast of water at high pressure is sent through special self-propelled nozzles into the lines that will usually remove blockages and build up. LoJac’s nozzles will differ depending on the application, drain size or type of clogged material Hydro jetting systems normally use about 35,000 psi, which works very effectively.

What We Do

HYDRO EXCAVATION SERVICES HYDRO EXCAVATION SERVICES

Hydro-Excavation, or hydrovac, is the process of using pressurized water to excavate material. The resulting slurry is then removed using a powerful vacuum system. Hydro-excavation is minimally invasive, fast, and effective. It is the ideal option for any of your digging needs, including: Utility Pole Installation Trenching Interior Excavation Landscaping As well as many more. LoJac’s trucks are specially equipped to conduct hydro-excavation operations at any temperature, making them perfect for work in freezing conditions. LoJac has been in business for over 30 years, and has become one of the premier hydro-excavation service providers in the greater Nashville area. We are proud to provide hydro-excavation options to various projects, both new construction and restoration.   How Does Hydro Excavation Work? Hydro excavation, or hydro vac, is the process of using pressurized water to dig and move dirt. Together, the high-pressure water breaks up the ground soil and the air vacuum transfers the slurry into the debris tank. Hydro excavation only uses pressurized water and an air vacuum system to complete the hydro excavation system. To utilize a hydro excavation unit, you will need a vacuum source, in which there are two options to achieve this. One is a fan framework and the other is a blower with a positive displacement capacity. The fan framework option is able to move an enormous amount of air. This allows for quicker excavation work and is easier to operate. This option is usually the less expensive route, compared to the positive displacement blower option. Displacement blowers are able to move air at a longer distance than the fan framework is able to. On top of that, a displacement blower allows excavation to be performed at greater depths, but it is at a slower rate. The fan system allows for hydro excavation work to be completed more effectively, but the displacement blower is good for deeper jobs.   Sign, Pole, and Line Installation: Hydro excavation is utilized for line, sign, and pole areas for its installation. It is similarly used for potholing or daylighting. It takes into consideration less congestion and traffic in the excavating region because hardware can be placed a good distance.   Funnel and Sewer Recovery: Funnel and sewer recovery is another application for hydro excavation. This strategy reduces dangers for any harm or punctures in the funnels. This eliminates the extra time and cost that fixes require.    Landscaping: By utilizing hydro excavation for landscaping, exact excavation is done so the surrounding soil isn't upset. The soil remains compact and solid while the important evacuation and is finished.   Soil Trenching Hydro excavation is utilized for soil trenching as well. Soil trenching is the process of digging narrow trenches in order to install cables, pipelines, and other types of in-ground utilities. Hydro excavation makes sure that the area that needs to be excavated is going to be altered because the unit has that capability with its exact precision. Also, a hydro excavation (or hydro-vac) is able to perform soil trenching work on frozen surfaces. They allow operators to use either cold or warm water to break down the frozen ground. Then they can vacuum everything into the attached debris tank. If you are looking for an efficient and non-destructive method of soil trenching, hydro excavation is the best option.   Debris Removal Hydro excavation trucks are able to remove debris and clean out structures without affecting any surrounding structures.  Traditionally, excavation equipment will need a larger area to work in to be able to be used properly. However, hydro excavation trucks have a boom component that is flexible and maneuverable more than traditional excavation equipment. The controls are at the operator’s fingertips, allowing them to control the boom’s exact height and depth. Hydro excavation equipment is able to remove both wet and dry forms of debris, which includes sand and rocks.   Advantages and Benefits Hydro excavation carries various advantages to the mechanical field.  It is currently the most used strategy for digging because of its productive and precise outcomes. The essential advantage of hydro excavation is that it offers better harm and security control when compared with other industrial techniques. Since it is exact, it limits accidents and wounds for workers and others in the surrounding area. It also provides super digging. Utilizing hydro excavation maintains a strategic distance from harming underground funnels, lines, and links. This kills the high costs required for repair and restorations.  The need for fewer repairs implies an ideal opportunity for business running. Interrupted with utilities bring burdens and high expenses. This procedure of excavation can limit damages.   Safety Benefits of Hydro Excavation Hydro excavation gives a method of digging and moving soil in a more secure way. It is a non-technician and non-damaging method. The workers will be protected from machinery accidents and the residents close by will be safe from construction accidents. Hydro excavation units include a high-pressure water hose and an air vacuum. In order to reduce clogs and traffic at the excavation site, the hydro excavation unit is able to be located further away from the excavation area.   Cost Benefits of Hydro Excavation The procedure of hydro excavation lessens many undesired impacts from traditional excavation strategies. It gives exact and precise work so harms to the encompassing pipe, utilities, and condition are significantly decreased.  For potholing, hydro excavation is able to move soil in a more accurate manner than other forms of excavation to install pipes and cables. The pipes and underground utilities will not be affected or harmed by the process because the water avoids the pipes, which prevents cracks or leaks.

SUBSURFACE UTILITY ENGINEERING SERVICES SUBSURFACE UTILITY ENGINEERING SERVICES

Subsurface Utility Engineering is a process of mapping utilities, including relocation, design, condition assessment, and communication of utility issues and cost estimates. LoJac uses vacuum excavation techniques to gather information needed for effective subsurface utility engineering. We can provide mapping for all quality levels defined by the American Society of Civil Engineers, depending on what exactly is needed for the particular project. Subsurface Utility Engineering work is primarily done at the early design stage of a project or for asset management. Early design work involves fully designing and implementing the utility system, while with asset management the client may not have a full map of the system and will need the subsurface utility engineering team to create a full map. LoJac is experienced in both forms of SUE. Subsurface utility engineering (S.U.E.) refers to a branch of engineering that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, communication of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design. The S.U.E. process begins with a work plan that outlines the scope of work, project schedule, levels of service vs. risk allocation, and desired delivery method. Non-destructive surface geophysical methods are then leveraged to determine the presence of subsurface utilities and to mark their horizontal position on the ground surface.  Vacuum excavation techniques are employed to expose and record the precise horizontal and vertical position of the assets. This information is then typically presented in CAD format or a GIS-compatible map.  A conflict matrix is also created to evaluate and compare collected utility information with project plans, identify conflicts, and propose solutions. The concept of S.U.E. is gaining popularity worldwide as a framework to mitigate costs associated with project redesign and construction delays and to avoid risk and liability that can result from damaged underground utilities. In 2003, the American Society of Civil Engineers (ASCE) published Standard 38-02 titled Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data. The standard defined S.U.E. and set guidance for the collection and depiction of subsurface utility information. The ASCE standard presents a system to classify the quality of existing subsurface utility data, in accordance with four quality levels: Quality Level D. QL-D is the most basic level of information for utility locations. It comes from existing utility records or verbal recollections. QL-D is useful primarily for project planning and route selection activities. Quality Level C. QL-C involves surveying visible above-ground utility facilities (e.g., manholes, valve boxes, etc.) and correlating this information with existing utility records (QL-D information). Quality Level B. QL-B involves the application of appropriate surface geophysical methods to determine the existence and horizontal position of virtually all subsurface utilities within a project's limits. Quality Level A. QL-A, also known as "daylighting", is the highest level of accuracy presently available. It provides information for the precise plan and profiles mapping of underground utilities through the actual exposure of underground utilities (usually at a specific point). It also provides the type, size, condition, material, and other characteristics of underground features. Exposure is typically achieved through hand digging or Hydro-Vacuuming. Subsurface Utility Engineering is mainly used at the design stage of a capital works project and when information is being collected for asset management purposes. In both situations, a similar process is followed but the scope of the work and presentation of the information may vary. When a S.U.E. investigation is carried out for a capital works project prior to construction, the objective is generally to collect accurate utility information within the project area to avoid conflict at the later stages of the project. For initiatives involving asset management, project owners may be missing information about their underground utilities or have inaccurate data. In this situation, a Subsurface Utility Engineering provider would collect the required information and add it to the asset management database, according to the four quality levels prescribed by ASCE Standard 38-02.

CCTV PIPE INSPECTION SERVICES CCTV PIPE INSPECTION SERVICES

LoJac offers a wide variety of pipe camera services, where we can insert our camera systems to inspect pipes for cracks, leaks, blocks, or other issues. Inspections with a camera are surgically precise, making them quicker and more cost effective than alternative methods of inspection. Pipe camera inspections are complex and required specialized equipment and the professional operators to use it. LoJac can provide assistance with any pipe camera services you may need for your new construction or existing project, no matter how big or small. LoJac is your committed partner in every step of your excavation or piping project, from initial mapping or inspection to the final build and installation. Our subsurface utility engineering, pipe camera service, hydro-excavation, and hydro jetting services work in tandem to provide you with a comprehensive experience from start to finish. CCTV Pipe Inspection A technique of utilizing CCTV video cameras to visually inspect pipes, stormwater lines, and sewer lines for cracks, infractions, blockages, and other defects in the line. This method is carried out by inserting our camera system into an opening in the utility line, either manually or with the help of remote control, which gives a video feed of the pipe's inside to an on-location screen for review. How does CCTV inspection work? The initial step of carrying out a CCTV video pipe inspection is to locate or make an entryway where the camera can be brought down into the line. When the camera is brought down into the line, it will give us a clear visual of the condition of the line and what is inside the pipe. An automated crawler is controlled from outside the line by viewing the crawler camera on a screen. A push camera, utilized for lines 6" or smaller in diameter, is a smaller camera that is pushed through the line by hand. A CCTV video pipe inspection can give data on the current condition of the utility line and recognize blockages, breaks, infractions, and different defects in the line.  Specific hardware is required to explore the lines and ensure the dividers of the pipes are appropriately lit to get the clearest picture possible. It is also important to know the number of access points, as the more access points we have, the more complete the examination can be. When our video pipe inspection experts recognize a region of interest inside the pipe, they will mark the area digitally within the film footage and from the surface by using technology to find the camera which will be translated to the PACP report. In addition to the condition of the line, our technology allows us to measure diameter, elevation, and distance from a reference point of the various noted conditions within the pipe or line. For what reasons do you need CCTV pipe inspection?  When your objective is to get a close view of what's inside drain lines, CCTV cameras are the right device. They are regularly used for the construction and development of the drainage system. Utilizing CCTV to recognize exact issues can be less expensive and more precise rather than exploratory digging.  For sewer lines and drainage systems, a video pipe examination is regularly used to decide the feasibility of using the current system's sections. It will help in saving thousands of dollars for the project owner to find that they can reuse existing areas of the system rather than installing new ones. There are times when sewer lines may get damaged and should be replaced. A CCTV pipe inspection will give data about the cracks, and locate faulty joints along the line that needs to be fixed. It can be feasible to fix the faulty joints instead of installing a whole new pipeline that will be costly and unnecessary. What we can evaluate through our service: · Pipe Grade and Depth · Pipe Temperature Measuring · Pipe Pressure Monitoring · Sewer and Pipe Integrity · Sewer and Utility Access Points · Obstructions in Sewer or Pipelines Why choose us over other service providers? LoJac's specialists offer you industry-leading CCTV sewer and drain inspection services. From the initial step and recording of inside the pipeline to an exhaustive audit of the recording and proof of any issues found during the review, we give start to finish CCTV sewer and pipeline services.
