Poly-Triplex Technologies has developed a permanent culvert rehabilitation solution to the increasing deterioration of America's infrastructure. The patented lining system offers excellent properties that rehabilitate and further strengthen compromised culverts.
The Poly-Triplex liner can be pulled through sections of deteriorated culvert pipe and cured-in-place using patented technology that allows for rapid installation and return to full use usually within twenty-four hours. Pipe diameter is not decreased and flow rate is generally greatly improved.
Load bearing tests on the Poly-Triplex liner reveal an increase in pipe strength worth noting. ASTM C497 D-Load Bearing tests used Wheeling galvanized corrugated culvert pipe with an ultimate load bearing strength of 1,377 lbf/ft. After this corrugated metal pipe was lined with the Poly-Triplex Liner Series 11,600, the ultimate load bearing strength had increased to 3,095 lbf/ft. The D-Load strength also increased impressively from 689 lbf/ft/ft to 1548 lbf/ft/ft.
Corrugated Culvert Pipe 110 feet long under 4-lane divided highway completely rehabilitated in one day with the Poly-Triplex Liner System with no traffic disruption.
