NPC, Incorporatedars erosion, freeze-thaw cycles, tree root invasion, and corrosion allow water to enter manholes and pipes through the adjustment area and joints. Municipalities all over the country are finding that investing in rehabilitation is a quick payback through extended system life and lower operating costs. The NPC Internal Joint seal can quickly and economically restore manhole and pipe joints to watertight condition.
The NPC WedgeLock Expansion Band provides a highly reliable and easy to install method of creating a watertight seal to ASTM standards. Our unique Expansion Band design allows the bands to be disassembled for easy passage through a manhole opening or pipe.
Our Internal Seals are available in two widths and a wide range of diameters to accommodate virtually any manhole or pipe sealing application. The 7.50" width can also be purchased with an extension flap that allows them to be overlapped for sealing larger areas. To determine the right sizes for your project, contact one of our sales or customer service representatives.
