TECO pile integrity tester

The TECO time domain system is used for checking the integrity of concrete piled foundations.

Using solid state memory the equipment is built for security of data and speed of operation. With a rugged yet lightweight casing, backlit LCD screen and waterproof connectors the TECO unit is easy to transport and can be used in inclement weathers.

A user friendly menu system guides the operator and displays data in an easy to follow format. Data is transferred to the windows based TEAP analysis software through a USB interface.

The site unit can measure pile length and provides the operators with a choice of filters to suit the application. This versatile system can be used to test pre-cast concrete, cast-in-place concrete and timber piles of most dimensions.

The TEAP2012 software is supplied as standard and provides an easy to use platform for analysing test results and producing reports. The software can tabulate the data and present all response curves either individually or up to 8 test results per page for comparison.

Response curves can be filtered and exponentially amplified to help detect weak responses from depth and signal polarity can be reversed to suit the users' preference.

Piles are tabulated and automatically stored into numerical order. The test results can then be accessed directly from the table.

The user is able to define what variables to include in report tables select different concrete velocities and save commonly used interpretations. Overall site comments can be included with the table and the user's company logo can be stamped on each page.

The print menu enables 4 or 8 plots per page to be presented and depth scales to be normalised.
