CETCO, a Minerals Technologies Company

As a subsidiary of Minerals Technologies Inc. based in Bethlehem, Pennsylvania, CETCO produces geosynthetic clay liners, water remediation technologies, waterproofing systems, and drilling products for environmental, industrial, and infrastructure applications worldwide. The company leads the global GCL market with its BENTOMAT sodium bentonite liner series, including the DN-HS configuration featuring high-density needle-punching for peak shear strength in seismic zones and heap-leach pads, and RESISTEX polymer-modified bentonite liners designed for aggressive leachate conditions like coal combustion residual containment. CETCO's proprietary Supergroove technology allows bentonite to self-seam at overlaps without supplemental material, and GCL permeability of approximately 5×10⁻⁹ cm/sec — roughly 20 times lower than compacted clay — pairs with sodium bentonite's ability to swell up to 15 times its original volume for self-healing performance. On the remediation side, FLUORO-SORB adsorbent holds NSF certification for PFAS treatment, capturing the full spectrum of PFAS compounds without co-contaminant interference. Additional water treatment technologies encompass filtration, flocculation, coagulation, in situ groundwater remediation, sediment capping, slurry solidification, and soil stabilization. The building products division provides above- and below-grade waterproofing membranes along with LIQUID BOOT and LIQUID BOOT PLUS vapor intrusion mitigation systems. CETCO backs its products with a GRI-accredited R&D laboratory offering leachate analysis, proxy testing, and site-specific direct shear testing.
