Logan Clay Products Company (LGNC), founded in 1890 and headquartered in Logan, Ohio, manufactures and sells vitrified clay pipe for sanitary sewer systems along with related building products. The company produces O-ring joint pipes, Y- and T-branches, pipe fittings including curves, elbows, saddles, increasers, reducers, double hubs and stoppers, and traps such as running traps, P-traps, shoulder hand hole traps, half traps and catch basin traps; it also offers building products comprising chimney tops, flue liners, sump pipes, meter boxes, wall copings and Rumford fireplaces, with recent emphasis on no-dig jacking pipe for trenchless installations. Logan Clay operates manufacturing facilities in Logan and Haydenville, Ohio, serving municipalities, utility providers and civil engineers primarily in the United States with corrosion-resistant, long-lasting clay products that support open-cut and microtunneling applications. In August 2023, the company acquired Silvesco, a pallet manufacturer in Marietta, Ohio, for $1.9 million, adding a 4.8-acre production facility and diversifying into hardwood pallets; it continues investments in facilities and personnel amid resurgence in vitrified clay pipe demand, reporting EBITDA of $4.6 million in 2024. Family-owned since Barton A. Holl's 1950 acquisition and now led by his grandson and great-grandson, Logan Clay trades on the OTC market with a focus on durable, low-maintenance sewer infrastructure.
