Geotechnical Services Gross Pollutant Traps and Non-Destructive Digging Methods

Geotechnical Services, Gross Pollutant Traps and Non-Destructive Digging Methods That Deliver Value and Efficiency to Your Projects

Because the ground for building and infrastructure projects may consist of various types of soils and structures such as the foundation, land reclamation, excavation pit, and so on, geotechnical testing service should be contacted to assist construction engineers with data collection, laboratory testing, field investigation and sampling, and geotechnical investigation report. Types of foundations include piles, drilled shafts, piers, caissons, and earth stabilised columns.

Knowledge of these ground foundations is crucial for the feasibility and durability of a construction project.

Geotechnical testing is performed by geotechnical engineers, geotechnical technicians, or engineering geologists to collect data about the physical properties under a worksite. Geotechnical testing services help building engineers in determining the suitability of the ground for a construction project, and for identification and marking of underground services as well as sampling and testing of different kinds of soils and rocks.

Aussie Hydro-Vac Services provides its geotechnical testing services with respect to project specifications such as type and difficulty of structure, expected ground conditions, geotechnical site investigations, groundwater sampling, and more. Undisturbed samples are taken at certain intervals to the borehead depth termination, and at the change of strata in borehole. Disturbed samples can be derived from selected recovered cores of standard penetration test (SPT). Undisturbed sampling using the open-tube sample as thin-walled or thick-walled tube samplers can be applied by the geotechnical testing service team, depending upon the soil conditions encountered.

SPT and CPT tests Standard Penetration Test (SPT) is performed in boreholes by a geotechnical testing services team in order to estimate consistency, relative density, and strength-deformation parameters of soils. SPT is performed at certain numbers and intervals to the borehole depth termination for all boreholes. Cone Penetration Test (CPT) can be performed by Aussie Hydro-Vac Services’ geotechnical testing service team to effectively evaluate the site characterisation. CPT is a valuable method to assess subsurface stratigraphy associated with organic soils, discontinuous lenses, soft materials, potentially liquefied materials, and strata containing cobbles and boulders.

Geotechnical laboratory testing Geotechnical laboratory testing done via geotechnical testing services includes index property tests for the classification of soils, and engineering properties tests to determine the strength and deformation methods. Also, rock strength properties tests and chemical analysis of groundwater is performed by Aussie Hydro-Vac Services’ geotechnical testing service team within the scope of its geotechnical investigations.

Geotechnical investigation services provided by Aussie Hydro-Vac Services include test pitting, tube sampling, augering, pavement and asphalt reinstatement, site characterisation, laboratory testing and professional interpretation of data obtained for site improvement.

Gross pollutant traps Gross pollutant traps are structures that use physical processes to trap solid waste such as litter and coarse sediments. They are commonly used as the primary treatment method as the traps mostly remove large, nonbiodegradable pollutants. These filtration systems are designed to prevent stormwater pollution from entering the waterways. These are usually designed to catch the larger trash, debris and larger sedimentation.

Gross pollutant traps are most commonly used as part of a treatment train with other stormwater treatment measures, such as wetlands or bio-retention systems. A variety of gross pollutant traps can be used by Aussie HydroVac Services based on your requirement but all of them trap litter and sediments above 5 mm in size for removal from the water system.

Advantages of gross pollutant traps The advantage of gross pollutant traps is that they have a relatively small lateral footprint and are hidden from view.

The traps also remove non-biodegradable, larger pollutants that would restrict, clog or block the flow of water in the downstream system. These are commonly installed with secondary or tertiary systems as a treatment train as gross treatment pollutants cannot remove fine sediments, dissolved and attached pollutants. Most gross pollutant traps are suited to pre-treatment of small to medium-sized systems but these are not effective in removing nutrients, and provide limited removal of fine sediment and dissolved pollutants. Aussie Hydro-Vac Services is servicing all types of gross pollutant traps in a variety of settings including tunnels, mills, restaurants, airports, shopping malls and through council contracts.

Non-destructive digging services In addition to gross pollutant traps and geotechnical investigation services, Aussie Hydro-Vac Services also offers nondestructive digging services for various construction projects in Australia. The company uses the best-in-class equipment and tools for non-destructive digging that ensures that there is minimum damage to the underground utilities and infrastructure, while the surroundings remain relatively clean. Non-destructive digging is an environment-friendly method as it creates less debris, and most of the debris can be used for refilling or reuse. Moreover, the equipment and trucks used by Aussie Hydro-Vac Services for its non-destructive digging operations can be placed away from the excavation site. This way, non-destructive digging is a preferred method of digging in congested areas as there is minimum disruption to the traffic.

Aussie Hydro-Vac Services also offers a range of non-destructive digging and non-destructive excavation services that include industrial cleaning and shutdowns, drain cleaning and culvert cleaning, and liquid & solid waste disposal. Technical services provided by Aussie Hydro-Vac Services include subsurface engineering & maintenance, surveying services, cable & pipe location, and engineering capabilities.
