エフ・デイー・イー Product Lineup

When the scale of the fire is large and the temperature experienced by the structure is high, the concrete may lose strength due to heat, and gaps may form between the materials, causing separation between the rebar and the concrete.

• Other services

It is to re-evaluate the seismic performance of existing buildings that do not possess sufficient seismic performance designed under old structural standards according to the current new seismic standards.

• Other services

In general, even in the case of partial defects, a complete renovation is necessary to achieve full functional recovery. Therefore, we will conduct a leak investigation and assess the condition of the building.

• Other services

The Schmidt hammer method is a way to measure the strength of concrete without causing damage, while the compression test method involves taking a core sample of the concrete and using a compression testing machine to measure the compressive strength, which is then compared and evaluated against the required design strength.

• Other services

In the ultrasonic inspection of FDE, the Sonic Searcher TR-300 is used to measure the thickness of concrete in structures, the depth of cracks, internal defects, sound velocity, etc., using ultrasonic waves (5k to 100kHz) and elastic waves.

• Other inspection equipment and devices

The areas indicated by the arrows in the infrared thermal image show the locations judged to be floating and bulging.
