These mains may include lines for telephones, electricity distribution, natural gas, cable television, fiber optics, traffic lights, street lights, storm drains, water mains, and wastewater pipes. In some locations, major oil and gas pipelines, national defense communication lines, mass transit, rail and road tunnels also compete for space underground.
Because of the many different types of materials that go into manufacturing each of these different types of underground lines, different detection and location methods must be used. For metal pipes and cables, this is often done with electromagnetic equipment consisting of a transmitter and a receiver. For other types of pipe, such as plastic or concrete, other types of radiolocation or modern ground-penetrating radar must be used.
Location by these means is necessary because maps often lack the pinpoint precision needed to ensure proper clearance. In older cities, it is especially a problem since maps may be very inaccurate, or may be missing entirely.
Whether you’re demolishing a building or drilling into concrete, it’s essential to know if there’s underground rebar at the site. Rebar is a type of reinforced steel used to improve the strength and tension of concrete.
Digging or drilling without first locating potential rebar in buried concrete slabs can result in damage to equipment, personal injury, and building collapse.
City Scan Corp can quickly and accurately identify the location and depth of rebar embedded in the structure using GPR.
As we strive for the best service in the industry, CityScan Corp has teamed up with Eastern Concrete Cutting Corp. to offer our clients a reliable source for all their concrete cutting and drilling needs.
