JENNCHEM marks its 10 Year Anniversary

August 2019 marks the 10 year anniversary of JENNCHEM’s inception. From its beginnings in 2009, JENNCHEM has grown into the industry leader in pumpable crib, cementitious grout, and polyurethane grout installation. Prior to JENNCHEM beginning operations, Tony Calandra had the vision to implement pumpable cribs, a technology that had not yet been perfected, as the standard for everyday use as standing support in underground coal mines. With industry-leading research and development and an investment into cutting edge technology, this vision has since become reality. After 10 years of serving the mining industry, JENNCHEM remains the worldwide industry standard for pumpable crib, mine seal, and polyurethane grout installation. JENNCHEM’s core values of safety, innovation, and customer service will ensure that JENNCHEM remains at the forefront of underground mining roof/ventilation controls and beyond.
