Radar icon.png


Ground Penetrating Radar (GPR) is a cost-effective, non-destructive method of obtaining information on items within concrete structures or below the ground. Our radar emits electromagnetic energy into the ground. When the energy encounters a buried object or boundary between materials having different electrical energy, it may be reflected, refracted or scattered back to the surface. A receiving antenna can then record the variations in the return signal. 

It allows construction professionals to make informed decisions before coring, cutting or digging.


  1. Avoid miscommunication between contractors by using one company to scan, core and cut.

  2. Reduce the risk of cutting conduits, reinforcement and PT cables located within the slab.

  3. Written report with images to identify areas in the concrete to be avoided.

  4. Ground Penetrating Radar (GPR) does not require exclusion zones on site.

  5. A non-destructive form of testing allowing the examination of the slab without damaging it.

​Coring can be carried out on floors and walls to a diameter of 450mm and a depth of 1500mm. CRLS carry saws that plug into a 10 amp electrical socket, have enough power to cut through a concrete slab and require minimal setup.

Our dust-free chase cutting saw is ideal for indoor use as it allows us to cut to depths of up to 100mm and any width required, without creating clouds of dust.

The very versatile and manoeuvrable Husqvarna 4800D road saw offers high cutting speed and capacity for floor or outdoor use. The three speed gearbox allows us to run different sized blades without having to change other parts, effectively saving time on the job. 

These services are ideal for plumbers, electricians, air conditioning installers, fire services installers and large commercial fit out projects.


  1. Avoid miscommunication between contractors by using one company to scan, core and cut.

  2. Care and attention to detail to minimise disruption to work sites.

  3. A variety of cutting equipment including electric, diesel and petrol saws to suit most situations.

  4. Our background in radar means we think before we cut. 

  5. Safe and clean work site from start to finish.

Working with Engineers, Architects, Project Managers and Site Managers, CRLS can manage, measure and monitor your projects with Remotely Piloted Aircrafts (RPA's), more commonly referred to as drones. We schedule flights to capture data in real time, producing high resolution photos, maps, reports for immediate analysis.


Keep projects on track by capturing data at key milestones of your choice, and create, compare, document and share a visual timeline with stakeholders. Regular monitoring of projects provides you with vital information to minimise delays and settle conflicts which may arise with contractors 
working on site.


After concrete has been poured, use the information previously gathered to decide whether changes to electrical, plumbing or mechanical penetrations are possible and won’t damage or destroy nearby inslab services when cutting or coring is undertaken.

Using the latest Remotely Piloted Aircrafts (RPA’s), CRLS can produce high resolution pictures of buildings, roofs and structures. We are able to reach areas which traditionally required specialist equipment and working at heights qualifications, saving you considerable costs.


Our industry leading software allows us to quickly and accurately (99.4%) inspect and measure roofs or structures to obtain aerial site intelligence in real time and create accurate high resolution maps and  reports for analysis. 


  • Track progress at any stage and communicate to key stakeholders

  • Get accurate on-site data in real time to streamline decision making

  • Identify and correct defects and deviations by comparing actual conditions to pre-construction design with the ability to overlay plans on the aerials images.

  • Improve safety by reducing the time spent on roofs, ladders and scaffolding

  • Generate accurate measurements for site planning and energy estimates

  • Eliminate time spent on site with trades to obtain quotes

  • Inspect solar panels for damage with real-time thermal imagery

  • Fast-track insurance claims by obtaining imagery without the risk of entering danger zones

​With our scanning equipment, we can accurately measure the thickness of a concrete slab, map and size reinforcement, and locate appropriate sites for core samples to be taken. We also offer chemical analysis of core samples, such as chloride and sulphate intrusion profiles, as well as carbonation. Onsite hardness testing can also be accommodated using our Schmidt Hammer. It will provide you with hardness results without the need for taking physical samples. Crush testing of core samples can be provided with strain gauges to measure flex and deformation.


  1. We have the necessary equipment to perform a combination of the different methods.

  2. Equipped to work in remote areas.

  3. Options for non-destructive testing available before performing destructive testing.

  4. We can arrange for samples to be sent to the lab. 

  5. Reports from worksite as well as lab reports provided if required.

CRLS offer written reports as a value-added service to our clients. Our reports contain information on the areas scanned, advice on slab thickness, reinforcing patterns and any other anomalies in the test area. These reports can be distributed to other trades and professionals involved in the project.


  1. Consistent information shared between stakeholders.

  2. A record of technical information and photos taken onsite.
