Snap-Tite’s Large Diameter high density polyethylene (HDPE) Lining System is the ideal solution for failing metal and concrete culverts of any size, including oval or arched. Snap-Tite is a cost-effective, no-dig solution with field-tested benefits. Years of experience and thousands of culvert projects have proven that rehabbing a culvert with the Snap-Tite system is the better solution. Using solid wall HDPE pipe, as well as state-of-the-art profile wall HDPE pipe, culverts rehabilitated using the Snap-Tite system actually outperform the original structures. The low resistance of flow (Manning’s N of 0.009) of HDPE pipe allows for greater flows. The use of gasketed or fused joints assures a watertight seal, easily meeting the requirements of ASTM D3212. Also, HDPE is of the most corrosion- and abrasion-resistant pipe materials available. Which means you can fix it, forget it and move on to the next challenge knowing Snap-Tite is a long-term solution.

Snap-Tite’s Large Diameter line is constructed of profile wall HDPE pipe meeting the ASTM F894 direct-bury sewer pipe requirements. These products offer all of the benefits of our solid wall line but in bigger diameters. The use of profile wall pipe provides lower weight answers at lower costs for even your largest culvert rehab needs. From our solid wall HDPE to our profile wall HDPE, the products offered by Snap-Tite have been selected based on the reputation of the manufacturers, the quality of their products and the needs of our customers.
Snap-Tite’s large diameter options are available in lengths from 20 to 50 feet long with special lengths available upon request. The pipe is joined together then pushed and/or pulled into the full length of the existing culvert. Unlike other rehab systems, the annular space between the old pipe and the new Snap-Tite is filled with a low-density cellular grout which fills any voids between the roadway and the culvert, delivering a truly ‘rehabbed’ culvert. Snap-Tite is also easy to install. Nearly all of the culvert renewal can be done off road with minimum disturbance to the right-ofway and without road closures.
