Culvert reline is made easy when using Weholite. 

Offered in sizes up to 132" ID, no host culvert is too big or too challenging. 

Manufactured to ASTM F894, from advanced, high density polyethylene resin, Weholite will not corrode, rust or tuberculate, providing exceptional performance over its 100-year design life. 

Pipe joining is made easy with Weholite threaded joints for sand-tight connections or water-tight using extrusion welding. 

For environmentally sensitive areas, Weholite can be fabricated with fish baffles, passages or flow attenuators. Selected and approved by DOT's, municipalities, cities and railroads.
