Perry Testing Limited offer a wide range of structural investigation, structural scanning and concrete scanning services to our clients. Reporting is issued in a timely manner to ensure that our clients receive the information they need to progress with key projects.

Concrete GPR Scanning

Construction requires careful planning and execution to be successful. Part of that planning is to carry out investigations on existing structures and concrete to locate and avoid any existing services or reinforcements. Damage to such services or reinforcements could lead to costly replacements and delays to the project, not to mention the potential for construction workers to be injured.

GPR concrete scanning technology can help you avoid this by allowing for a detailed structural investigation to take place. This can identify any areas that need to be avoided, making sure that any pre-existing works are not damaged during the construction process, allowing our clients to cut and core into concrete with confidence.

As well as checking existing works, GPR concrete scanning can also be used to check new structures to make sure they are free from faults, such as voids, and that the depth and density are correct. Once complete, the comprehensive scans and detailed reports Perry Testing Ltd provide can be used for building acceptance inspections and quality control audits.  

The three services Perry Testing Ltd offer are explained in more detail below, but if you have any questions contact us. We have experienced engineers on hand to talk through your needs and offer you expert advice.

GPR Scanning Location

GPR-Scanning Location

GPR scanning (also known as Ground Penetrating Radar) is now increasingly used in engineering and offers a unique non-invasive and non-destructive method to characterise the subsurface and subsurface features. GPR scanning can be used on a wide variety of materials; most commonly soil, concrete and asphalt, for a thorough GPR survey. GPR scanning can be used in the following ways:

  • Construction Detail – GPR scanning can determine the general arrangement of construction, changes in material type, location of structural steelwork and layer thickness.
  • Concrete Mapping – GPR scanning can be used to inspect concrete floors, walls, decks, slabs, tunnels, balconies, warehouses and garages. It can locate rebar, tendons, conduits, voids and measure slab thickness.
  • Service Location – GPR scanning is the only non-destructive technology that can identify non-metallic as well as metallic subsurface utilities. It is suitable for the location of services including water, sewer, gas, electric, telephone and fibre optic.
  • Foundations – GPR scanning is a useful tool for the location, investigation and determination of the extent of footings and foundations.

Hilti Ferro Scanning

Our engineers use the Hilti Ferro Scan to provide a fast, accurate method of determining reinforcement location, size and cover. Unlike GPR scanning, the Ferro Scan will give an accurate cover and an estimated bar diameter. Our reports are used by our clients for quality control and building acceptance inspections. They are also used to avoid costly damage caused by cutting through structurally significant reinforcement. We can provide accurate depth of cover measurements for reinforcement at depths of up to 100 mm.
We can provide on-the-spot structural analysis and depth of cover assessment. The images can then be overlaid into CAD for client reports which aid with future designs and can be used to avoid striking reinforcements when positioning holes.
