Joint Seal - Piezo Sensors attached using Fabick FX-1.1 Joint Seal

To install a piezoelectric sensor a slot is cut into the concrete or asphalt around 3/4 wide and about 1 inch in depth. A piezo can come in different length. The piezo is then placed in the slot and Fabick Joint Seal is used to fill and encapsulate the sensor.

The joint seal is important in a number of ways:

1. to fill the slot.
2. to encapsulate and protect the sensor.
3. most important is to transfer the vehicle information (load) to the sensor (see graphs).
4. speed at which FJS sets up - hardens.

If there is a failure in any of these points the Piezo will fail. The cut slot must be sealed from moisture, the joint seal must give a good signal in all weather conditions and must last for a given length of time.

FJS opens the traffic lane back up to traffic faster than the competition, which allows the workers to do more installations and make the roads safer because traffic is redirected for a shorter period of time.
