Terminology

Asbestos

was a popular building material widely used in construction industry between 1945 - 1980 because of its ability to be used in a wide range of applications, durability and affordability. In Australia the use of asbestos material has been banned since 2003 due to the serious illness caused from inhalation of the asbestos fibres.

Cable locating

is the process of identifying public utility mains which are underground. These mains may include lines for telephone, electrical, gas, cable, fibre optics, storm drains, water mains, and wastewater pipes. Many different types of materials go into the manufacturing of underground lines therefore different detection and location methods should be used. Metal pipes and cables are often located with electromagnetic equipment. For other types of pipe, such as plastic or concrete, ground-penetrating radar may be used.

Cathodic Protection

is a technique used to control the corrosion of a metallic surface by making it the sacrificial cathode of an electrochemical cell.

CCTV

Closed Circuit Television 

CCTV survey inspections

is a system used to visually inspect the structural condition of drains, pipes and conduits.  CCTV is a cost effective way to identify blockages, root intrusion and damaged pipes.

Chemical root treatment

The intent of chemical root treatment is to kill tree roots in sanitary sewer lines and to inhibit root re-growth without damaging the trees, the environment, or the treatment plant. The active ingredient for killing roots shall be a non-systemic herbicide which will kill roots at low concentrations but which will not permanently affects parts of the plant distant from the treated roots. The active ingredient must be spontaneously detoxified by natural chemical/biochemical processes following its use.

Dial Before You Dig (DBYD)

is a free national referral service designed to prevent damage and disruption to the vast pipe and cable networks which provides Australia with essential services.

Drill slurry

Is an slurry consisting of water and either a mineral such as bentonite or a polymer and is used when soils are sandy and prone to caving. The ingredients are mixed in the hole or mixed externally and pumped into the hole and later displaced with concrete.

Earthing Fault Locating

This process of locating faults in an earthing grid or an earthing system is circuitry which connects parts of the electric circuit with the ground. Significant plant installations like factory sub-substations are required to have an earthing grid which is network of cooper cable buried under the ground which forms part of the electrical system and is also a safety protection system to prevent electrocution of personnel. The cables corrode or break due to movement with in the ground.

Fiber optic cable

An optical fiber (or optical fibre) is a flexible, transparent fiber made of high quality extruded glass (silica) or plastic, slightly thicker than a human hair. It can function as a waveguide, or “light pipe” to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics.

Gernie

A water pressure washer, usually a basic configuration of a water inlet, water pump, hose and a hand piece with a trigger and nozzle.

GPR

Ground penetrating radar.

Hydro-excavation

is the process of using pressurized water and the high powered vacuum to simultaneously and service safe break up of soil. The soil and water slurry is conveyed by vacuum to a debris tank which results in the fast production of precise excavations that require less backfill and time to restore. This process also has less of an environmental impact than traditional excavation techniques.

Hydrovac Truck

this is a truck that is equipped for and used to for Hydro-excavation, Non-destructive excavation or Non-destructive digging which ever term you want to use.

Mitigate

is the act to reduce the probity (likeliness) of the occurrence of an event or the extent of an unwanted event.

Mud

can be wet dirt or soil or Is an slurry consisting of water and either a mineral such as bentonite or a polymer and is used when soils are sandy and prone to caving. The ingredients are mixed in the hole or mixed externally and pumped into the hole and later displaced with concrete.

Non-destructive excavation

is the process of using pressurized water and the high powered vacuum to simultaneously and service safe break up of soil. The soil and water slurry is conveyed by vacuum to a debris tank which results in the fast production of precise excavations that require less backfill and time to restore. This process also has less of an environmental impact than traditional excavation techniques.

The soil and water slurry is conveyed by vacuum to a debris tank which results in the fast production of precise excavations that require less backfill and time to restore. This process also has less of an environmental impact than traditional excavation techniques.

Potable water

(which grade) water that has been treated and safe for humans to drink.

PVC pipes

PVC pipe which is made from polymerized vinyl chloride, a synthetic resin, which when plasticized or softened with other chemicals has some rubber-like properties. The resin is derived from acetylene and anhydrous hydrochloric acid.

PPE

Personnel Protective Equipment refers to protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury.

Pot-holeing

It is the process of excavating a hole in order to locate a utility that's location is shown on a “Dial before you Dig” drawing or suspected to be in the area. This method allows for as little material as possible to be removed in order to verify the location and what utility is there.

Recycled/ Reclaimed water

is former wastewater (sewage) that is treated to remove solids and certain impurities.

Root barrier

is a physical underground wall, placed so that structures and plants may cohabit happily together

Root intrusion

Root intrusion is one of the most destructive and costly problems a property owner faces when maintaining a residential or commercial sewer drainage system.  Most property owners are surprised to find that roots not only cause problems in landscaped areas, but also will frequently “travel” great distances to penetrate a small hole in a drainage pipe.

Service locating

is the process of identifying public utility mains which are underground. These mains may include lines for telephone, electrical, gas, cable, fibre optics, storm drains, water mains, and wastewater pipes. Many different types of materials go into manufacturing each of these underground lines therefore different detection and location methods should be used. Metal pipes and cables are often located with electromagnetic equipment. For other types of pipe, such as plastic or concrete an ground penetrating radar may be used.

Strip Trenching

is the digging of narrow trenches, for installing and locating underground utilities pipes, cables. Unlike traditional slot trenching methods, which can cause serious and costly damage, hydro excavation provides a non-destructive and efficient method. Hydro excavation makes it easy and safe to install sprinkler systems, locate, and perform similar installations without the risk of damaging previously installed systems or lines.

Slot trenching

is the digging of narrow trenches, for installing and locating underground utilities pipes, cables. Unlike traditional slot trenching methods, which can cause serious and costly damage, hydro excavation provides a non-destructive and efficient method. Hydro excavation makes it easy and safe to install sprinkler systems, locate, and perform similar installations without the risk of damaging previously installed systems or lines.

Smoke testing

is the process of generating smoke and then introducing it into a system under pressure and then watching for the smoke to coming out.

Sustainable practices

The practice of recycle, reuse, reduce.   

Topographical Survey

is to gather survey data about the natural and man-made features of the land, as well as it elevations.  From this information a 3D map may be prepared.

Trial Pit / Holes

an excavation of the ground in order to study or sample the composition and structure of the sub-surface, usually dug during a site investigation, a soil survey or a geological survey. Trial pits are dug before the construction. They are dug to determine the geology and the water table of that site.

Triple interceptor

is a drainage device used to retain trade waste such as grease, fat, oil, silt, sand, sludge and other substances to prevent their entry into the sewerage system. Triple interceptors vary in design according to their application.

Utility

refers to infrastructure or a set of services provided for public consumption.  Some utilities may include: electricity, natural gas, water, sewage and network/ telephone.
