Our In-house Brands

PDI is constantly innovating.  Sometimes, we apply our engineering and design talents to products of our own.  Over the years, we have built our in-house brands to the point where they make up 30% of our business.  Contract manufacturing for our customers will always be our priority #1, but manufacturing our own products allows us to grow and become more resistant to nationwide economic changes.

Ag Solutions was founded in 2003 by the Glazik brothers, Steve and Gary. Together, Steve, Gary and Steve's sons Matt and Alex manage farmland in Ford, Iroquois, Champaign and Vermillion County in Illinois of corn and soybeans. The soil in this area responds well to strategically placed tile systems to remove excess moisture from the ground, but it only works if the tile system remains clog free!

That's why the brothers invented the Quick Drain Intakes which allows more water in while keeping leaves, stalks, and other debris out of the inlets.  While Ag Solutions has mainly been focused on agricultural drainage products, the company has also been able to expand to equipment upgrades such as the Acre Plus which allows you to carry over a bushel more of seed in your John Deere and Kinze planter boxes.

Since 1997, we have been making construction supplies under the brand name Glazelock, a play on our founders' last names "Glazik".  Glazelock shims lock together making them ideal for commercial buildings.
