QUALITY FROM THE GROUND UP
How It’s Made
Tidewall controls every step of the manufacturing process — from raw material sourcing to finished sheet — so quality is never left to chance.
Recycled Window-Grade PVC
We source and process only window-grade vinyl — the highest quality PVC compound available.
Vertically Integrated
From material acquisition through extrusion — we control the entire process, no outsourcing.
Precision Extrusion
Tight tolerances on wall thickness, flange angles, and lock dimensions ensure a straight, strong wall.
The Manufacturing Process
Tidewall is produced from highly weatherable, impact resistant recycled PVC compound. Through our parent company Regenex Corporation, we control the recycling process from material acquisition, to cleaning, sorting and grinding, to insure a high quality compound. Other vinyl sheet piling manufacturers are not vertically integrated to this degree.
This carefully prepared compound is then extruded into the finished Tidewall shapes. Careful attention is paid to the physical specifications; wall thickness to maintain strength, the flange angles to make a straight wall, and the male and female lock dimensions to insure ease of installation. Careful and consistent calibration and cooling of the part is required to maintain straightness. Pigment is added to produce the required color, with light grey being the standard, but other colors also available.
Mono-Extrusion vs. Co-Extrusion
Tidewall produces both mono-extruded and co-extruded products. It is important to note that both methods can produce high-quality walls.
Mono-Extrusion
One compound extruded through the entire thickness of the part — uniform composition throughout.
Co-Extrusion
Two compounds extruded simultaneously — a substrate for mass and a weatherable cap for exposed surfaces.
Regardless of which method is used, all Tidewall compounds are highly weatherable, impact modified compounds — inside and out. Our vertical integration gives us a significant cost advantage over other manufacturers, which is why, despite the use of premium raw materials, Tidewall sheets are always competitively priced.
