![]() Since the integrity of the adjoining pipe is not affected, the problem is isolated to one small section. No longer does the entire area have to be retrenched to expose the suspected line. The result: less time, effort and materials.Īdd to that the fact that if any one cable should experience a "burnout", the replacement process is drastically reduced. No waiting for a ready mix truck, no need for forms, no worry over pipe moving. Gone is the more time consuming and labor intensive process of laying conventional conduit that must be braced and then encapsulated in concrete. The removed earth, if clean, is then back-filled into the open trench. Contractors can use any one of a series of configurations to create their own custom "duct bank". Once the desired trench is excavated, sections are connected easily by plastic couplings that are attached to specially formed ends. Square on the outside, and round on the inside and 4 feet at its longest length, this unique shape allows sections to be stacked on one another. "Okay, how is concrete conduit installed?" To answer that question we will need to describe what a length of conduit looks like. There is no better environment for electrical current than non-conductive, heat dissipating concrete duct. Put the two together and you have the perfect medium for which cable can traverse. That is what concrete conduit looks like when stacked in a trench. Now picture for a moment a honeycomb pattern with all its many cavities. Each line must be protected, yet segregated from one another. Think of an underground power network with dozens of cables traveling for miles. How can we make this claim? First we need to tell you a little more about the concept of this unconventional product that we aptly call "Concrete Conduit”. "It" is concrete and thanks to improvements in extrusion technology, "concrete conduit" has again flourished as the most cost-effective means of transmission available. Ironically today a company named Roman Stone is using it to manufacture conduit to carry electrical current to millions of consumers. Posts that fail to meet above requirements will be removed.As early as 200 BC the ancient Romans used it to build aqueducts to distribute water throughout their cities. r/AskElectricians /r/askanelectrician /r/diy /r/homeowners /r/electrical.
