CertainTeed Certa-Lok™ PVC well casing is the industry leading choice for lining as well as monitoring of potable drinking water wells. Certa-Lok™ utilizes CertainTeed’s field-proven spline-locking design to form a full strength joint instantly in all weather conditions. It does not require the use of solvents, arc welding or reinforcement screw attachments.
Certa-Lok™ pipe provides a restrained joint by utilizing precision-machined grooves on the pipe and in the coupling/integral bell which, when aligned, allow a spline to be inserted, resulting in a fully circumferential restrained joint that locks the pipes together. A flexible elastomeric seal (O-ring) in the coupling and/or integral bell provides a hydraulic seal.
Note: If needed, the joint can be disassembled and re-used to allow for system changes, extension or removal for re-use. Certa-Lok™ joints can be easily disassembled, allowing for system changes, extension, movement or reuse of the entire system.
Certa-Lok™ is ideal for a wide range of water well applications, including:
• Aquifer Storage and Recovery
• Geothermal
• Municipal
• Irrigation
Standard pipe color for Water Well applications is WHITE.
