AristoScan offers a non-invasive inspection of concrete structures. This includes, but not limited to, walls and floors, measurement of slab thickness, reinforcing mapping, post tension cables, conduits, detection of voids and any anomalies in the concrete structure using ground penetrating radar. Our latest concrete scanner has an inbuilt live power sensor, which assists in tracking live power in concrete.

Concrete scanning can be completed in 2D or 3D with the option of a detailed report for your records. It can be used in every construction site and operations for detailed analysis of the concrete structure and comparison with the as-built drawings. GPR scanning of concrete can also provide moisture content and the possibility of corrosion.

We have a range of concrete scanning equipment to suit almost any situation. We also have the ability to carry out large scale post tension cable mapping with geo referencing to cm accuracy using our multi-array GPR system.

We service the domestic, commercial and industrial sectors, and are happy to provide an obligation-free quote on request.

Utility Locating

This is a service we provide for basic utility locating. This is a cost-effective, non-destructive method and is generally completed prior to any excavation work.

This service utilises an EM (Electromagnetic) locator and accessories required to locate any services you are looking for. This could include, but not limited to, electrical, communications or water. There are occasions where a single or dual antenna GPR (Ground Penetrating Radar) unit may be used to verify or assist in this work, due to non-conductive utilities such as pvc pipes.

Any services located are marked on site using spray paint for your referencing.

Utility locating plays an important role. Any ground excavation has the potential to damage a utility service if not located prior, which could cause timely delays and costly repairs. The worst thing that could happen is injury or someone not returning home to their loved ones.

This method utilises GPS assisted software that can map your utilities on a cartographic background with cm accuracy.

Utility mapping eliminates the loss of the utility locates due to the loss of paint markings. It is also on your records for the life of the utility, so you only have to locate that service once.

For example, if you have a utility location completed for a job and that job is delayed for some reason, you may lose your markings from the locating which was marked out using spray paint. With the utility mapping service Aristoscan provides, you have no issues. You simply refer back to your site map which was completed on that given day.

For those larger projects, Aristoscan has a multi-array GPR unit, which utilises GPS with a cartographic background to provide cm accuracy of scanned utilities. This system scans approximately 900mm wide and produces 3D scans in a single pass.

An array GPR system is simply the term applied to a GPR system containing multiple transmitting and receiving antennas deployed over a spatial volume with fixed spatial locations defined for each element. Array GPR systems can be used to map large areas quickly and enable true 3D visualisation of the subsurface.



GPR arrays also enable faster data collection of a much richer dataset compared with traditional 2D systems. For example, a 32-antenna array with 4 cm antenna spacing can collect data 32 profile lines at 4 cm spacing in one swath, whereas a 2D system would need to collect 32 individual lines at 4cm spacing to replicate the result of an array. This is simply not economical. In saying that, there are circumstances where a single antenna unit is still required, so we still have this available for that very reason.
