FAQs

All customer feedback is important to use, especially questions. We’ve been getting a few of the same questions lately, so we decided to answer them here. If your question still hasn’t been addressed, feel free to contact us and ask.


Why would I want to use concrete scanning?

The purpose of concrete scanning is to determine whether your concrete slab contains conduits, post-tension cables, rebar, or any other hidden dangers.


Concrete slabs can make up your floor, roof deck, ceiling, or any other concrete flat horizontal surface. Conduits, which are tubes or pipes used to conceal wires, may be embedded into a concrete slab to provide electricity to a building or buildings. Post tension cables are steel wires in a plastic sheath used in concrete construction to allow for thinner slabs to be used and for greater lengths between support columns. They stay in and are “tensioned” after the concrete is poured. Rebar is also a steel structure used to reinforce concrete, which stays in the concrete slab after it is poured.


Digging into any of these structures when completing demolition work is dangerous. Damaged electrical wires can take power from surrounding buildings, damage machinery and injure workers around it. Ripping out post-tension cables and rebar can be damaging to the machinery and take down parts of the structure that you didn’t mean to take down. Unexpected crumbling of buildings can not only ruin your plans for the rest of the area but also injure others onsite.


We at GeoRadar use GPR concrete scanning technologies to inform you about where dangerous elements lie in your concrete so that you can complete your demolition work safely.

    What is a jet rodder?

    A jet rodder is a machine used to hose down a pipe or pipes to remove blockage and waste. Otherwise known as a high-pressure jetter or sewer jetter, it has a high-pressure flexible hose attached to a precision nozzle. We use a drain camera to guide the jet rodder down the pipe, then pump water into it for it to force out of the nozzle in powerful jets. The jet of water washes away the source of the pipe blockage.


    The difference between a jet rodder and a high-pressure water cleaner – which is a device you can attach to a hose – is the jet rodder has even higher pressure to unlock bigger drains faster and more effectively. At 5000psi, a jet rodder can cut through oils, fats, old waste, blockages and even tree roots.


    The reason why a jet rodder is the preferable method to clean pipes is because it causes no damage to them. Whereas traditional pipe cleaning methods might require destructive excavation, the high-pressure water from the jet rodder doesn’t affect the pipes around it, only the build-up of material inside the pipe. 


    We have a jet rodder for hire to clean your stormwater drains, pipes and more. Hire a jet rodder from GeoRadar for your project anywhere within the Wide Bay and Burnett regions.

      What is microtrenching for?

      Microtrenching is the process of creating a slot in the groundwork of roads, concrete fixtures and other hardscaping features for the installation of fibre-optic cable lines.

      “Hardscaping features” are any human-made features used in landscape architecture, like paths or walls.

      Fibre-optic cable lines are similar to electrical cables but contain optical fibres, which are used to carry light. The inclusion of these elements determines the use of the fibre-optic cable. Some are used for long-distance telecommunication, whereas others are for providing a high-speed data connection between different parts of a building.

      Fibre-optic cable installation only requires around one-inch wide trenches, called microtrenches, for installation. The depth of these is calculated by an engineer depending on their location. A saw blade cuts through the hardscaping feature, then the micro-trench is appropriately protected and backfilled, and the fibre-optic cables are laid down.

      Microtrenching eliminates the need to rip up roads and footpaths for fibre-optic cable installation and allows for the easy restoration of the hardscaping features it lies under. There is no need for heavy machinery, extensive road closures and labour hours and weather delays with microtrenching. It is more convenient, environmentally friendly, aesthetically pleasing and cost-efficient than traditional methods, and gets buildings on the network faster.
