Polywater | Hauff-Technik’s wall entry PZVR sleeve and PGKD sleeve system guarantees a watertight seal. The PZVR wall sleeve has a proprietary epoxy Cementous coating on the outside of it so that it bonds with the concrete. Cut pieces of PVC conduit swells up during the curing process of concrete and then shrinks creating gaps and cracks along its length allowing water to enter structures. The PZVR can be ordered or cut to size and is available in sizes from 2” inches through 12” inches. Secure end caps on the ends of the PZVR also help to mount it to forms so that you have a secure sleeve during pouring.

The PGKD conduit and pipe seal has a patented visual indicator that shows the installer and the owner that the seal was installed correctly. All stainless-steel parts, no loose hardware and no torque wrench is needed to install this product. The PGKD is gastight and watertight up to 72.5 PSI (5 bar).
