GPR is used frequently in construction. Ground penetrating radar, or GPR, is used in construction every day, though you may not know it. Also known as ground surveying, GPR is a non-invasive, geophysical mapping method that uses radar pulses to image under the ground.
Epoxy injection is an economical method of repairing non-moving cracks in concrete walls, slabs, columns and piers and is capable of restoring the concrete to its pre-cracked strength. Prior to doing any injection it is necessary to determine the cause of the crack. If the source of cracking has not been determined and remedied, the concrete may crack again.
FRP Composite System - PT and Non-PT
Fibre-reinforced polymer (FRP) is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, or aramid, although other fibres such as paper or wood or asbestos have been sometimes used. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic, and phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries.
FRCM or Fabric-Reinforced Cementitious Matrix combines high-performance sprayable mortar with a carbon-fiber grid to create thin-walled, reinforced concrete shells without adding significant weight or mass to the structure.
