It’s a growing problem. Culverts installed decades ago under hundreds of interstates, expressways, highways and rural roads are failing
at an alarming rate — victims of age, erosion, wear and tear, and structural failures. Thousands of corrugated metal culverts are so significantly rusted that a danger of sink holes, road collapse or flooding exists. Concrete culverts have cracked
or pulled apart at the joints, creating similar dangerous scenarios. Federal and state DOT engineers and contractors are scrambling to find a solution that is economically feasible, quick, and avoids costly road closures and detours.
The Snap-Tite® HDPE Lining System is that no-dig solution, and has become the first choice of roadway engineers and DOT crews/contractors for many reasons:
- Utilizes durable, flexible high-density polyethylene pipe (HDPE) with male/female machining, allowing it to be ‘snapped’ together for a secure and water tight joint, meeting ASTM D3212 requirements, as well as AASHTO Standard M326.
- Available in lengths from 2 feet to 50 feet long; available for existing culverts with diameters from 8 inches to 84 inches, including oval culvert applications.
- Nearly all installation work can be done off road, keeping workers and motorists safer, with less traffic disruption and minimum disturbance to right of way.
- Installation is easier, done with light duty equipment — there is no digging. Most highway departments or contractors can use their own crews without the need for special training or specialized equipment.
- In most cases, the rehabilitated culvert will have the same — or greater flow — than the old culvert.
- Dollar for dollar, Snap-Tite® is more economical and provides longer life than other outdated culvert rehabilitation options.
