7/26/2021 0 Comments Vacuum Excavation and Pavement Investigation Services for all Soil Types and Terrains to Keep Your Underground Utilities IntactVacuum excavation allows workers to accurately identify utility depths by removing material from around the piping network, plumbing pipelines, and sewers, as well as for dry potholing. The method enables rapid excavation and storage of material within the system's storage unit. Vacuum excavation is also a clean, cost-effective and environment-friendly method as it does not require the use of harsh chemicals.
Hydro vacuum excavation combines high-pressure water to safely uncover underground utilities without damaging underground utility components or puncturing pipes. A jet of high pressure is more aggressive than air and can therefore cut through almost any soil type. This vacuum excavation process uses water to loosen and reduce the strength of soil, making it easier for the operator to vacuum cut the excavation area and move it into the tank. The key to efficient hydro excavation is to use enough water to cut the soil efficiently. The residual slurry spoils are easily extracted into the debris tank via a positive displacement blower, or a centrifugal compressor. Hydro excavation is typically more productive than air excavation Hydro vacuum excavation is recommended for vacuuming not only around water mains, but also around sensitive utilities such as electrical boxes, gas lines, and fibre optics, as well as in areas where you are unsure where the utility is and do not want to use traditional mechanical digging methods. When dealing with frozen areas, the hydrovac vacuum excavation technique can be used to thaw the area for digging. Hydro excavation is typically more productive than air excavation in most soils as the process cuts and erodes the soil more rapidly. Air vacuum excavation is typically used to safely uncover sensitive underground utilities that can’t withstand water pressure. Air vacuum digging is desired in applications where the soil tends to be loose, and water is not readily available. Where immediate backfill of the hole is required, transportation companies, power plants, and other utility companies prefer air vacuum excavation. Due to its lower operating pressure requirement, air vacuum excavation is also preferred around buried electrical lines or brittle utilities. Use cases for non-destructive digging Other application uses of vacuum digging and vacuum excavation include fibre optic repair, repairing water main breaks, installing light poles, pressure testing, and hauling fresh water to a job site. As a hydro excavator consists of a powerful vacuum system, water tank and an onboard water blaster, the technique of vacuum digging and vacuum excavation can be used for anything that requires spraying, washing, or vacuuming. Lowering the cost of returning the site to its original condition Since vacuum excavation and vacuum digging eliminates the need for abrasive methods used in hand digging, the process allows on-site workers to remain safe on the surface while preventing the possibility of trench cave-ins and accidental line damage. Vacuum digging and vacuum excavation methods offer unmatched safety proposition to the contractors, lowering insurance costs and reducing job-site downtime. As the overall size of the work area can be minimised, vacuum excavation and vacuum digging methods allow the service provider to lower the cost to return the site to its original condition, without the piles of debris to be dealt with later.

7/22/2021 0 Comments Accurately Assessing the Serviceability and Performance of Structures Using Advanced Geotechnical Investigation and Geotechnical Testing ServicesGeotechnical investigation and geotechnical testing services provide project engineers with the knowledge of ground conditions so that they can make well-informed decisions regarding the feasibility of a project. The investigations have acquired substantial importance in preventing loss of lives and material damage due to foundation cracks, earthquakes, and other catastrophes. The purpose of the geotechnical investigation is to investigate the soil and geologic conditions of a property, and to provide recommendations and design criteria for construction purposes. Geotechnical testing services can be as simple as conducting a visual assessment of the site only, or it could be as detailed as a computer-aided study of soil involving laboratory analysis and testing of the soil and rock conditions and other parameters.
Geotechnical investigation and geotechnical testing services are used to ensure that the substructure, which is eventually going to hold up a structure, is safe and enduring. The below-ground investigation is an integral part of any construction project wherein the soil strata is sampled and tested to establish its characteristics, which may have an influence on a construction project outcome. The serviceability and performance of the structure depends largely upon the accuracy of the geotechnical investigation carried out by the geotechnical testing services provider. Conducting testing and investigations adhering to international standards A geotechnical investigation must take place prior to foundations being laid for any building work. Aussie Hydro-Vac Services provides geotechnical investigation and geotechnical testing services using advanced technologies to determine the suitability of the ground for creating structures. Geotechnical testing services and geotechnical investigations are carried out by Aussie Hydro-Vac Services in strict adherence to international standards and guidance in order to provide you with the highest level of field investigation and sampling, laboratory testing and geotechnical investigation report data. Expert investigators and testers at Aussie Hydro-Vac Services have extensive knowledge of topography maps, geology maps, and climate and weather data, and regional geology conditions of South East Queensland, Brisbane, Gold Coast, Northern NSW, Western and Central Queensland, and other parts of Australia. The following investigations and testing may be done by technicians and surveyors of Aussie Hydro-Vac Services: Soil sampling and investigation: The undisturbed samples are taken at certain intervals to the borehole depth termination and at the change of strata in the borehole. Disturbed samples can be derived from selected recovered cores of standard penetration test (SPT). Undisturbed samples using the open tube sample as thin-walled or thick-walled tube samplers can be applied depending upon the soil conditions encountered, while undisturbed sampling that uses the piston sampler can be applied for low-strength fine soils, such as silt and clay. Standard Penetration Test (SPT): The test is performed in boreholes in order to estimate relative density and strength-deformation parameters of soils. SPT is carried out in weak-weathered rocks at certain numbers and intervals to the borehole depth termination for all boreholes. In addition to soil samples, SPT can also be used for soil classification purposes. Rotary core drilling and rock sampling: A sample of core/cuttings is collected within a tube with the help of a flushing medium. The quality of rock recovery achieved is determined by the geotechnical investigation services team using rock quality designation (RQS), total core recovery (TQR) and solid core recovery (SCR) ratios that are recorded and reported for each core run of the geotechnical investigation. Cone Penetration Test (CPT): CPT is performed by the geotechnical investigation team to evaluate effectively the site characterization, and assessing potentially liquefiable materials such as sand and granule gravel, organic soil and discontinuous lenses. Geotechnical laboratory testing: This geotechnical investigation is conducted to determine the specific gravity of the soil solids, determination of the plasticity index of soils and moisture content of the soil. Engineering properties tested during a geotechnical investigation by Aussie Hydro-Vac Services may include a consolidation test to determine the magnitude and rate of consolidation of soil, and strength and strain-stress relationships of cohesive soil. Additionally, a rock strength properties test can also be conducted to classify rock strength and determine the unconfined compressive strength of intact rock core specimens.

That’s why it is important to use professional cable location services, pipe location services and draining CCTV inspection services to understand the exact location of any buried underground utilities before undertaking any excavation project.
To detect underground utilities, cable location services and pipe location services providers may use either passive or active location detection methods. Some signals may already be present on the existing underground utilities, such as an electromagnetic field, that can be detected by a surveyor with the help of the passive detection method. However, when no current is flowing, the buried electrical cables cannot be detected by cable location services using the passive detection method. In fact, up to 60% of buried utilities can be missed by cable location services or pipe location services when they use a passive mode alone for detecting these underground utilities. So, the surveyor may choose to employ an active mode by applying an electrical current or signal to the buried metallic utility, which enables it to be traced and identified easily. Auto mode may be used to confirm the presence of utilities on the first site visit. Connection mode is the most efficient way of applying the signal to an underground utility. This method allows the operator to apply signal directly to the utility, and thus identify and trace its path. Non-metallic, plastic, and concrete pipes can be detected by using a tracer wire laid along the detection line used by the surveyor. Drainage CCTV inspection services Drainage CCTV inspection services help surveyors in carrying out all types of drain and sewer inspection surveys. Aussie Hydro-Vac Services uses state-of-the-art HD cameras and sewer inspection systems to view the interior of buried drain and sewer utilities. The skilled surveyors carrying out drainage CCTV inspections can check for depth, evaluate the condition of the sewer or drain line, and identify safe access points without causing any damage. Drainage CCTV inspection technique used by Aussie Hydro-Vac Services utilise CCTV video cameras to inspect pipes, blockages, infractions, stormwater lines, and other defects in the drainage pipelines. The surveyor will insert a camera into an opening in the utility line that provides a video feed of the pipe’s inside to an on-location screen for review by the surveyor. Your sewer lines may get damaged and require replacement. Drainage CCTV inspection by Aussie Hydro-Vac Services will give you all data about existing and potential cracks and locate faulty joints along the line that need to be fixed. It may be possible to fix the faulty joints instead of installing a whole new pipeline. For this, specific equipment is used by Aussie Hydro-Vac Services to explore the lines and ensure that the dividers of the pipes are appropriately fit to get a clear picture. This process can result in significant cost savings when compared to a replacement. Before carrying out any excavation work, it is important to know what lies beneath the surface. Aussie Hydro-Vac Services provides cable location services, pipe location services and drainage CCTV inspection services in Brisbane, Gold Coast, and other areas in South East Queensland.

It will then be vacuumed out using a powerful pumping system. The wet soil mix is stored in a truck for safe disposal to an offsite designated dump location. Hydrovac excavation can be performed in any type of soil, even in frozen grounds, and up to 70 feet deep. Water is used in hydrovac excavation because Australian ground becomes too hard for trenching during winters that makes traditional tools and methods ineffective.
Hydrovac excavation is effective at breaking up wet or rocky soil, clay as well as hard and compact dirt. During winters in Brisbane and Gold Coast, hydrovac excavation is recommended as hot water can be employed to breakup tough, frozen ground and permafrost. Water converts hard ground into sludge which is collected through a hose with the use of vacuum suction. It is then neatly connected into the storage tank connected to a trunk. It’s a cost-effective and inexpensive method which is not labour-intensive. This is also a precise method of excavation as the pressurised water is aimed directly at the exact point that needs to be excavated. Neat and clean operation Hydrovac excavation is used across industries in Australia due to its non-destructive nature, efficiency, and accuracy. As it offers a higher level of directional control and accuracy, hydrovac excavation is preferred for city locations within a small area with sensitive surroundings such as underground utilities that require special care. There is minimal or no damage to the underground fixtures and your property. As the suction is excavated by the water and vacuum, dirt and debris are simultaneously removed due to the process of hydrovac excavation. With the traditional digging methods, you are left with a huge pile of dirt and debris at the completion of the project tossed to the site to be dealt with later. This does not happen with the Hydrovac excavation. Hydrovac excavation process saves time and money in the long run as you do not need to devote time for clean-up and to repair the damage caused by the huge industrial machines. Ensuring that your landscaping is not destroyed Aussie Hydro-Vac Services utilises the latest techniques and equipment for hydrovac excavation that maintain the integrity of your utilities while ensuring public safety and environmental protection. The dirt excavated due to the process of hydrovac excavation is collected and simultaneously stored in the debris tanks, keeping the worksite clean with minimal disruption to traffic. The company uses advanced techniques of hydrovac excavation, such as daylighting and slot-trenching to dig slots and smaller areas in the ground to find or install electric lines without destroying anything in the process. Experts at Aussie Hydro-Vac Services also ensure that landscape of your worksite is not destroyed, and everything remains where they are during and after the hydrovac excavation process except the excavated soil. Liquid waste removal, disposal and treatment solutions If you require liquid waste removal and liquid waste disposal, Aussie Hydro-Vac Services can be contacted for its most efficient transport and treatment as the company uses advanced methods for its treatment to minimise impact on the environment such as ultrafiltration, and electrohydraulic cavitation. Ultrafiltration is a membrane technology which is designed to separate species based on particle size down to as small as 1 to 10 nm. The technique is used to concentrate liquids that are present in waste streams such as bilge water, black water, and grey water. Electrohydraulic cavitation is used for treating biological fluids, molten salts, and organic solvents. Various methods used for liquid waste treatment Another method used by Aussie Hydro-Vac Services for the treatment of waste collected from the process of liquid waste disposal and liquid waste removal is the biological treatment of wastewater. It is commonly used for the wastewater removal and wastewater disposal of conventional sewage treatment plants. The wastewater is mixed with microbial cultures under either aerated or air-free condition. The organic matter in the wastewater is transformed into low molecular weight species by the microbial action and then converted into mineralised products and carbon dioxide. The process results in the destruction of disease-causing organisms and viruses. However, this is not a promising method for liquid waste disposal consisting of grease, oils, plastic and paper. Root zone treatment is most commonly used as a treatment method for liquid waste disposal and liquid waste removal for relatively clean domestic wastewaters like bathroom shower, kitchen water and sink water. The liquid waste is sent through a sedimentation tank and then through various additional filtration processes. This finally results in the water that meets the necessary standards for release into the environment. However, its complex installation means that the method may not be available in some areas. More services for you to choose from Other methods used by Aussie Hydro-Vac Services for the treatment of waste collected due to liquid waste removal and liquid waste disposal include solidification, sedimentation, dewatering, composing, incineration and more. Other industrial services offered by Aussie Hydro-Vac Services include drain cleaning, vacuum loading, emergency response and spills, cable and pipe location, drone photography services, and many more. Aussie Hydro-Vac Services has many plants and vehicles to accomplish excavation tasks of all complexities such as Cap Combi drain cleaning unit, trailer vacuum excavation unit, CCTV & Geotech vans, emergency response vehicles, and a lot more. Contact Aussie Hydro-Vac Services for all your excavation, digging, waste management and cleaning requirements for commercial, residential, and industrial projects in various parts of Australia. 7/7/2021 0 Comments Cost Efficient Vacuum Excavation and Pavement Investigation Services with Minimal Disruption to Surrounding and Underground UtilitiesDuring the vacuum excavation process, highly compressed air is used to excavate the soil and suck it out in a dry condition. When this process is performed using a jet of high-pressure water instead of air, it is then known as hydro-vac. Vacuum excavation can be performed for large depth applications like the cleaning of storage tanks and silos. This method can also be used to vacuum out pipe sewage systems constructed underground.
With vacuum excavation and vacuum digging, underground utilities such as cables, pipelines and sewer lines can be appropriately exposed without causing them any damage. It is considered the safest excavation procedure to conduct excavation and digging safely and within proximity. Vacuum digging works best when you need to dig areas close to pipelines or any underground utilities. The excavation method is also used for drainages near the rails and to suck the ingested sand from rail areas. Vacuum excavation and vacuum digging techniques are used for the removal of toxic liquid waste, solid spills, or removal of contaminated soil and gravel. The method can be used by both businesses and residences to improve the soil around trees, and to eliminate tree roots that can create a mess around underground utilities such as pipelines and cables. A vacuum excavation test slot can be conducted by expert technicians at Aussie Hydro-Vac Services before conducting any groundwork for drilling or vacuum digging operations. The uses and benefits of hydro-vac services Vacuum excavation is used to prevent damage to existing underground utilities during the excavation process. Depending on the ground condition, the earth to be excavated will be loosened by the experts at Aussie Hydro-Vac Services using compressed air or a powerful water jet. The use of water in vacuum digging helps in breaking up stiff soil, and the slurry produced is removed by air vacuum. The vacuum required for the vacuum excavation process is generated either through a fan system or using a positive displacement blower. The material is sucked into the holding tank by passing through a micromesh filter system to trap the dust particles. In cases where the vacuum digging employs hydro-vac excavation, the debris is in the form of slurry which is extracted by a powerful vacuum system into a debris tank. Why pavement investigation services are required Information and data pertaining to soil and rock properties may be required for a variety of reasons and purposes. For such operations, pavement investigation using geotechnical resources may be needed. Today, pavement investigation and maintenance is a well-established construction engineering concept. A road with irregular pavement, corrugations, patches, and excessive cracks also affects the costs involved in the operation of vehicles. Aussie Hydro-Vac Services offers pavement investigation and maintenance services to industrial establishments, businesses, and residents in Australia to evaluate their serviceability, which is a measure in a given period of time of how the structure serves a driver for the three main purposes intended:
