Importance of Ground Penetrating Radar in the Location of Buried Utilities

Ground penetrating radar uses imaging technology to explore the subsurface of the earth. Also known as 'GPR', it uses electromagnetic wave propagation to create images and identify the changes in the ground's magnetic and electrical properties. GPR systems can be used to monitor the structural integrity of airport runways, find underground utility lines, for forensic research, land surveying for construction purposes, and detection of land mines.

Advanced ground penetrating radars are versatile and can locate a large range of metallic and non-metallic materials. GPR control equipment ranges from small and compact systems for short-range depth and basic data processing, to larger systems designed with 3D scanning and built in geolocation capabilities.

High antenna frequency ground penetrating radar is a non-destructive tool to evaluate the location of steel and other embedments in concrete. The scanner allows fast on-site imaging before drilling, cutting, inspection, and coring of concrete slabs in the absence of design drawings. Lower frequency antennas are better suited to surveying for utilities in soil or for analysis of soil layers. An ultra-wide band antenna is the ideal tool for utility location with the depth penetration required and improved imaging of smaller more shallow embedments.

Radio waves are used to find objects with varying dielectric constants. Hence, materials like metals, plastics, and filling can be found. This means conduits, rebar, power cables, water pipes, gas pipes, and other services can be found, too. Ground penetrating radar can be used when scanning bondek or post tensioned concrete slabs. And because GPRs are non-destructive testing equipment, they are safer and can help save a lot of time and money while ensuring accurate results and precise analysis.

A ground penetrating radar system can help analyse the physical properties of soil at depths of up to 500mm or deeper, depending on the circumstances. It requires only a single operator, and the scans can be accomplished in reconnaissance mode or along drawn grid lines if you want to create a 3D model. This way, the system offers a cost-effective and non-destructive soil inspection solution.

Advantages of Universal Testing Machine

The main advantage of investing in a universal testing machine is that the device can be used to test the strength, durability, and suitability for most any material. A universal testing machine has the capability to pull, compress, bend, or stretch material to its breaking point. It is primarily used by laboratories that manufacture and or mould different types of plastics. A universal testing device features one or two vertical columns mounted on a base. A second horizontal plate contains attachments that are used to hold the sample and slides up and down during stress testing samples. Dual vertical column machines are preferred by most laboratories as they can handle larger samples in terms of size and weight. Determining tensile strength is the most common test performed in a universal testing machine. This is done by holding one end of a sample in place while the other is pulled away until two sides are torn apart. The same process is used for testing flexural str

Uses for Universal Testing Machine

Universal testing machine or UTM is aptly named as it can perform various types of tensile and compression tests on different materials. There are also many different terms used to refer to a UTM that you will commonly hear in the industry, among the most popular of which are a tensile tester, bend tester, and compression tester. Some types of UTMs are stripped of some capabilities and/or are marketed to specific sectors, like texture analyzers for food, peel tester for adhesives, labels, and tapes, and top load compression tester for pipes and packaging. True UTMs can perform all of these and more. They are great multi-purpose instruments for any QC or R&D laboratory. The following are only a few common uses for UTMs: Tensile testing – One of the most common applications for UTM, a tensile test measure how strong a material is, how long it can stretch, and how stiff it is as the material is pulled apart until breaking point. Compression testing – Compr

Precautions to Be Taken While Using a Piezometer

The piezometer is a measuring device that determines pore pressures underground and liquid pressure. By determining pore pressure, you can understand the behaviour of the ground before, during, and after a construction project. Certain precautions must be taken when using a piezometer to ensure proper usage and the accuracy of results. Here are some of them: Have the right equipment – Invest in a state-of-the-art piezometer that uses a proven method of converting fluid pressures on the sensitive diaphragm into frequency signals which are ideal in the demanding environment common with civil engineering applications. Modern piezometers are capable of long distance signal transmission without degradation. They can tolerate wet wiring conditions and resist external electrical noise, too. Some manufacturers make piezometers specific for different applications, for instance, you should be able to find one with a heavy-duty body that can be b
