Cross Hole Sonic Logging (CSL) Tubes

Improve Your Next Project With Cross Hole Sonic Logging (CSL)

Cross hole sonic logging (CSL) is the most requested test method for drilled shaft integrity by Departments of Transportation (DOTs) throughout the United States. CSL test pipes are usually attached to the reinforcement cage along the entire length of the shaft.

What Is CSL Pipe Used for in Construction Projects?

Pittsburgh Pipe’s CSL pipes are composed of steel or PVC pipe. Steel pipes are typically preferred over PVC pipes because PVC material can debond from concrete due to heat from the concrete hydration process. Debonded pipes often lead to inconsistent concrete test results.

Our CSL pipes are frequently used as a quality assurance measure to guarantee the stability of drilled shaft foundations and structural integrity. Our customizable CSL pipes can also be used to test slurry walls, auger cast piles, mat foundations, and mass concrete pours. This type of testing can also be performed to determine the integrity of a drilled shaft by finding potential problems like soil intrusions, sand lenses, or voids.

Concrete Foundation Testing Cylinders and More

Pittsburgh Pipe is a premier CSL testing pipe manufacturer in the United States with over 40 years of steel experience. We can design and manufacture CSL pipes for any construction project by applying the feedback we’ve received from our customers across the country.

We can manufacture CSL pipes to custom-fit each drilled shaft based on the total length of the shaft. Our advanced process reduces material waste and time spent cutting in the field. It also saves our customers money with assets that handle any degree of foundation testing.

We can pre-thread pipes in lengths from 1 foot to 42 feet. We use malleable iron couplers to join the CSL pipes together or malleable iron caps to close off the end of the pipe. Pittsburgh Pipe ships your specially designed CSL pipes straight to the jobsite, ready to be installed. All exposed threads are carefully protected with durable thread protectors, which eliminate any potential damage during shipping.

How To Reduce Construction Costs for CSL Testing

Construction projects are expensive. However, there are ways to reduce overall costs while ensuring concrete integrity:

Order the Right Materials

As mentioned previously, CSL testing pipes come in steel and PVC materials. The wrong CSL pipes could result in crumbling foundations. Ordering the right materials for your construction project ensures you have what you need for a durable concrete structure.

Customized Testing Pipe

Pittsburgh Pipe’s CSL pipes are customizable for every construction project. Customizable CSL pipes reduce labor costs and increase overall project productivity.

Customized testing pipe reduce labor costs because workers spend less time cutting, threading, and piecing components together and more time completing the visual inspection. In addition, customized testing pipes get the project done quicker and according to the predetermined timeline.

Partner With a Reliable Concrete Testing Equipment Supplier

CSL pipes offer many benefits for concrete construction projects, including increased productivity, reduced labor costs, and enhanced accuracy. CSL testing pipes are more reliable than sonic echo testing because they can detect structural defects as well as the extent, depth, and approximate location of those defects.

Since 1977, Pittsburgh Pipe has been a trusted concrete testing equipment supplier. We’ve given contractors, distributors, and suppliers reliable and fully customized piping solutions for any construction project that comes their way. We build CSL pipes to your specifications and deliver your products when you need them. Our locations in the midwestern United States allow swift truck, rail, and river transportation. You always receive the right pipe, right on time.
