PDS creates technologically advanced, amazing products.
We have specialized in the production of bentonite pellets for over 30 years. Our tenacious ingenuity has led to the development of a technologically advanced, biodegradable non-stick time release coating which allows the bentonite pellets to be poured into place through standing water without sticking together or bridging. This capability provides the highest density per cubic foot of any existing grouting method – wet or dry.
PDS Pel Plug bentonite pellets are available in 1/4″, 3/8” and 1/2″ sizes.
The Pel Plug TR30 time release coated bentonite pellets can reach depths of up to 500 feet. Double coated (TR60) and triple coated (TR90) pellets are also available to further delay pellet swell times in cases of deeper water setting applications.  For more information on PDS products or services call 800-243-7455 or go to pdscoinc.com.
