PVC Well Casing

CertainTeed - the name that contractors have come to associate with the industry's broadest line of high quality PVC well products - is also the industry leader in high performance slotted well casing. Using new manufacturing technology, slotted casing can now be produced with open areas and efficiencies that rival those of other screens, often at a fraction of the cost. Combine PVC screens with PVC well casing for the ultimate corrosion-resistant, low-maintenance water well!

A Size and Joining System for Every Application Slotted casing can be produced in sizes from 2" all the way up to the largest commercially available PVC well casing product (17.4" OD), in a variety of wall thicknesses and strengths to suit virtually all applications:

  • Domestic
  • Irrigation
  • Municipal
  • Aquifer Storage and Recovery
  • Environmental

CertainTeed also offers a choice of joining systems: traditional solvent-weld or the contractor-proven, all-weather Certa-Lok TM mechanical joint.

Slot Width Selection

A wide selection of precision-machined factory slot designs (.010" - .125") with closely spaced inlet openings provides for uniform development over the length of the screen and proper stabilization of the gravel pack.

Long Life

Well rehabilitation costs are minimized, as PVC screens are inherently more resistant than conventional steel products to clogging and encrustation. PVC also outperforms stainless steel in highly corrosive environments, at a fraction of the cost. All screens are manufactured from PVC casing that is listed by NSF International as safe for use with potable water.

Single Source for All Your Well Product Needs

No more unloading, local-machining, and repackaging required. With CertainTeed, the industry's best slotted casing is shipped ready to use - no field fabrication required - along with your other PVC well product needs, including solid casing, drop pipe for submersible pumps, and a variety of fittings.


Slotted PVC casing is also ideal for use as underdrain pipe. Applications include, but are not limited to: Leachate collection systems for solid waste landfills.

Drainage and dewatering applications

Mining heap leach projects - special heavy-wall products, SDR13.5 and thicker, are available

PVC underdrain pipe is supplied with precision-machined slots, which provide greater intake capacity and continuous, clog-resistant drainage of fluids, as compared to standard round-hole perforated pipe. Slotted underdrain reduces entrance velocity into the pipe, thereby reducing the possibility that solids will be carried into the system. Slot rows can generally be positioned symmetrically or asymmetrically around the pipe circumference, depending upon the appliction. Outside diameters are generally the same for PVC and non-corrugated polyethylene (HDPE) pipe. However, the HDPE pipe must be extruded with a thicker wall (and therefore a reduced cross-sectional flow area) to obtain a comparable stiffness rating.
