The MIRA uses ultrasonic waves to build a 3D image of the features within a concrete pavement. It can be used to detect:
• Thickness: Concrete thickness estimation up to 3 feet deep with high accuracy
• Delamination: Detection of cracking in the PCC layer or de-bonding between PCC layers
• Reinforcement/Dowel bars: Accurate estimation of reinforcement depth
• Joint diagnostics: Detection of concrete deterioration, dowel position, spalling, etc. at PCC joints.
EMA has been using the MIRA recently to detect joint activation and he says the device makes it very easy to detect whether a joint has deployed or not. Just place the device over the sawn joint and in 2 seconds it displays the ultrasonic image on the screen and saves the data internally for later processing on a laptop.
Concrete GPR Scan in Daytona, St. Augustine, Cocoa, Melbourne, and surrounding areas can locate rebar and post-tension cables within the concrete using Hilti PS 1000 state of the art GPR scan technology. Reinforcing steel locations are marked directly on the concrete surface to ensure safe and efficient drilling that will preserve the integrity of the structure and reduce the need for repairs or patching. This helps our clients conduct core drilling without accidents, injuries or delay. Concrete GPR Scan is also useful when preparing for a renovation that includes electrical outfitting, plumbing, fire protection services, drain installation, and ductwork.
CONCRETE GPR SCAN DAYTONA
Also crucial in the Concrete GPR Xray Scan Daytona imaging process is determining what’s in the concrete structure. This includes gauging the concrete thickness, what the rebar content is, its spacing and its elevation within the slab. This extensive, critical information helps our clients and their teams to understand the makeup of the concrete. we also can determine concrete covers over the rebar using state of the art equipment.
VOIDS DETECTION AND LOCATIONS
We can also locate voids – air gaps between the sub-grade, dirt and the concrete slab-on- grade – hidden below concrete or asphalt surfaces. This degradation occurs over time due to compaction, pipe ruptures or erosion but is often undetectable on the surface. EMA Concrete GPR ground penetrating radar can help our clients locate these areas and – most important – avoid collapses.
COST OF CONCRETE GPR
Concrete rebar GPR testing are less expensive than XRAY due to its accuracy. The equipment is more expensive and a minimum of 2 operators is needed at all times. As a rule of thumb, concrete x-ray will cost double the hourly rate of GPR – although pricing by image may be more attractive for both parties. $150-$170 per image is fairly standard, combined with a mobilization charge of several hundred dollars. Night and weekend work is charged at 1.5 times standard rates which can lead to overtime rates too.
Protection from radiation is an important aspect of industrial radiography. The International Atomic Energy Authority (IAEA) had developed basic safety guidelines regarding the practice.
