Most large diameter pipes or water mains are made primarily of Steel or Concrete. Both systems often need either a AWWA approved cement lining installed or seam work completed. HydraStone has developed the cement lining, HydraKrete – 61, that is Certified to CSA – NSF ANSI – 61 Standards for potable water applications. The HydraKrete cement mortar lining was developed specifically for lining potable water mains. It conforms to AWWA specifications which ensure a high performance lining with excellent corrosion resistance. The HydraStone pipe lining division also lines the pipe by hand or machine in place or at the manufacturers facility. HydraStone’s expert applicators can quickly complete joint, patch & repair work very efficiently to eliminate unnecessary downtime.
