The Coimbra B-Portagem Mondego Metro project is part of the public mass transit system of Coimbra, Portugal. Dextra has played a significant role by providing Sonitec tubes for pile testing.

Dextra supplied Sonitec tubes for testing a total of 67 piles ranging in depth from 12 to 19 meters. The tubes were instrumental in conducting these tests with the Cross-Hole Sonic Logging (CSL) methodology.

The innovative push-fit connection system of Sonitec greatly reduced labor time during installation. Thanks to this user-friendly system, the contractor experienced smoother and more efficient pile testing processes. By eliminating the need for additional labor-intensive procedures, the contractor saved valuable time and resources. It also ensures a secure and reliable connection for pile testing.
