Through our partnership, 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 add Xypex Admixture to our concrete when fabricating our sewer products. This waterproofing compound provides added assurance that the environment will be protected from potentially harmful waste products. For more details, contact Hawaii Precast Inc today.
