Certa-Lok™ PVC Well Casing utilizes CertainTeed’s field-proven spline-locking design to form a full strength joint instantly in all weather conditions. No solvents, arc welding, or reinforcement screw attachments are required.
And now, with the introduction of small to medium diameter (4"- 8") Integral Bell Well Casing, the best joint in town just got better! Certa-Lok Integral Bell Well Casing is supplied with a conventional belled-end joint for even faster assembly.
Designed and manufactured to meet or exceed the requirements of ASTM F480, all Certa-Lok PVC Well Casing products are also listed by NSF International as safe for use with potable water. Certa-Lok is ideal for a wide range of water well applications, including:
Domestic Irrigation
Municipal Aquifer
