Papworths Construction Testing Equipment

Construction of a building begins below ground level – because that is where foundations are made. Foundations support the load of the entire building, and that is why every measure is taken to make sure that they are constructed right. Take piles, for example – once they are cast, there is no way of knowing if everything went alright. Earlier, in order to check if piles were casted right, they used to be pulled out – which defeated the whole purpose. These days, Ground Penetrating Radar is used to check consistency and homogeneity of anything that is underground in the construction industry. Principle of GPR GPR makes use of a high frequency radio signal. When you place the device on top of the structural element you want to examine, the device emits a radio signal which travels through the structure, and returns to the device. It works exactly like a radar or sonar – if there are any anomalies in the homogeneity of the structure, the behavior of the radio signal will show up...

Ground penetrating radar (GPR) is state-of-the-art equipment used for exploring the subsurface of the earth. The cutting-edge imaging technology found in high-end GPR systems measures electromagnetic wave propagation and echo from the subsurface, which images and identifies changes in the magnetic and electrical properties beneath the surface of the earth. Hence, GPR systems are useful in locating underground utility lines in earth or post tensioning and reinforcing in concrete. Ground penetrating radar is surprisingly versatile for many other applications, including forensic research, land surveying, detecting unexploded land mines, conducting groundwater studies, and monitoring the structural integrity of airplane runways. GPR is useful in many different fields. It is used to study ice, groundwater, soil, and bedrock under earth sciences and it may be helpful in finding diamonds and gold nuggets in alluvial gravel beds. In that case, ground penetrating radar is used to fi...
