Complete testing services

R.W. Sidley has a full-service testing laboratory accredited by the state of Ohio and approved by the Ohio Department of Transportation (ODOT) and Pennsylvania Department of Transportation (PennDOT). We also conduct testing at individual plant locations during production processes. Most of our products are tested daily, and critical products like filter media sand are tested multiple times a day. We continually evaluate our products to identify the slightest change in consistency. This way, we can take immediate corrective action and minimize variations.  


Independent laboratory tests are often necessary to conduct chemical and physical analyses of our finished products. We use nationally trusted and reputable labs but will also accommodate customers’ requests to coordinate material sample retrievals and deliveries to their preferred labs.  


Internal test results are recorded and compared with outside lab results. We keep detailed records of all tests and provide them to customers upon request so they can rest assured knowing the products they order meet their exact specifications.
