Watch the Video illustrating Josam’s WEJLOC® bond

The non-puncturing bond of Josam’s WEJLOC® Design


What does this video prove? This simple demonstration of inserting a piece of paper between the collar and body of a Josam floor drain and picking the drain up by the paper, clearly illustrates the positive non-puncturing bond of a waterproofing membrane to a Josam drain. This bond is made possible by Josam’s WEJLOC® design. The WEJLOC® design offered exclusively by Josam is available on both Josam floor drains and roof drains.
