Anchor-Lok® lined, precast concrete sumps eliminate major construction and provide an economical answer to costly downtime when corrosion-resistant, lined sumps are required. Sumps are built to specification and transported to site for installation. Applications include manholes, sumps and pumping stations that have been exposed to a variety of chemicals in a plant's waste effluent line. Installation is easy. Precast sumps utilize corrosion-resistant 3/16" thermoplastic sheets and an anchor and connecting system that mechanically locks lining into concrete. Sheet lining materials conform to all applicable ASTM and DIN standards. Atlas Minerals & Chemicals, Inc. 1227 Valley Road, P.O. Box 38 Mertztown, PA, 19539-0038
