Reliable Manhole Fabrication
Through our partnership with Walker Hawaii Precast, our skilled craftsmen design and fabricate sewer manholes that meet the standards of the County of Hawaii – Wastewater Division.
Our manholes include Alok Pipe–to–manhole gaskets, access rungs, and cast iron manhole covers, proudly made in the USA by D & L Foundry. We typically incorporate Avanti International waterproofing solutions into our concrete during the fabrication of our sewer products. These materials provide added assurance that the environment is protected from potentially harmful waste products. For more details, contact Hawaii Precast Inc today.
