Dextra America launches US-made Sonitec CSL tubes
Dextra America has launched a US-made “push fit” designed sonic tube system for Crosshole Sonic Logging (CSL) testing of concrete. Sonitec tubes facilitate the integrity testing of foundations and are compliant with ASTM D6760, Buy America and Buy American Acts.

In the USA, Sonitec® comes in two different models:
- Sonitec Plus is a 2 inches Schedule 40 steel pipe with an enlarged end in a bell mouth shape for instant connection: it makes for quick and easy push-fit installation. It is produced in compliance to AASHTO standard.
- Sonitec Slim sports a lighter design, with a thinner wall thickness and a diameter of 2 inches, resulting in over 70% weight reduction. It also features the same push-fit design for quick and easy installation.
Both models are tested and qualified in the U.S.A. and withstand pressure exceeding 725 psi.
