Direct Buried Duct
* Micro trenching done on Asphalt/Concrete road by Hydraulic wheel saw (Diamond cutting) * MicroDuct placed inside micro trench. * Trench Size 12mm Wide X 150 mm Deep is cut into the tar road using the DappermuisLicense. * Duct size 10/5.5 mm * Duct wall thickness 2.25 mm * Installation Direct bury (1 to 4 nos) * Avoid most of the protective materials as in case of DBC * After installation blow the micro cable * Micro trench is sealed with Ferment, a type of poly concrete * All the advantages of Micro technology available

After cuttng the trench through the tar road a 10mm foamstrip is inserted. Upto 5 microducts are stacked on top of each other, allowing a total of 12 fibers to cross the road. On top of the ducts a 10mm rubber cord is placed, then a 20mm steel spacer are inserted and the Ferment poly concrete poured to seal the micro trench. The concrete pavement itself is cut with a the wheel saw to run the fiber from building to building and then repaired using PolyConcrete. See http://www.dutchguard.com/p-EZCRETE.html

The fiber are cablejetted into the microducts, CableJettingAndPipes
