Case Studies

Water Recirculation Pit

San Louis Potosi, Mexico

Project Scope

Install a flexible PVC liner in a concrete pit to solve a failed coating problem.

Challenge

The applied coating in a water collection pit was flaking off and causing contamination in the spray wash of the production line. These flakes were causing rejected parts as the plant was trying to go on-line for the first time. From the initial inspection the failure appeared to be the result of poor substrate preparation.

Solution

To rectify the problem, the project engineers selected a flexible PVC liner from Witt Lining Systems. A Witt Liner is not bonded to the concrete, so the failed coating did need to be sand blasted off of the substrate. This meant the liner could be installed immediately. With no curing time the liner could also be put into service immediately, saving days (if not weeks) of remediation work.

Results

Installation of the liner was performed by H3 Services and completed over two days. Incoming piping was handled with pipe boots. Where there was a core-drilled hole, leading to the collection sump, a compression ring was used to seal the liner to the wall. With the new liner installed, the failed coating could no longer contaminate the water used on the production line.

Since 1972 we have been the industry leader in providing flexible PVC corrosion resistant liners. Flexible liners are a cost effective alternative to bonded Linings and coatings. Flexible PVC liners are used in plating tanks, chemical tanks, storage tanks, waste water treatment pits, secondary containment, cooling towers, pits, sumps, solar heated water storage tanks, or anywhere liquid containment or corrosion protection is desired.

Industries served include metal finishing, plating, anodizing, aerospace, oil and gas, mining, municipal water treatment, and food and agriculture. Witt offers a variety of materials such as Koroseal®, Spectra Blue® and Exceline®.  Witt Lining Systems also offers alternatives to PVC, custom fabricating Teflon® , Kynar® PVDF , and XR-5® liners. Wiitt offers a variety of liner grades and thicknesses to suit your lining need.  Links
