Department of Public Works and Highways (DPWH) Leyte 2nd Engineering District chief Margarita Junia said that as the area in Culasian village in Capoocan is confirmed landslide prone, they will install coco nets before the end of the year or early next year.
“We have identified road section to put a coco nets but no funding was released because it is not along the national road. So with that landslide there, we can see that the area badly needs this kind of project. This is applicable to mountain sides of Barangay Culasian,” Junia said.
Earlier, the road section was closed to traffic for five hours on midnight of October 25 due to major landslides following days of heavy downpour in the province.
Instead of concrete creeksides and embankments, coco nets made from coconut husks are tapped to prevent landslides.
Coco nets are derived from the fibrous husks of coconuts. The fiber extracted from discarded coconut husks, which is commonly called coco coir, has to undergo further twining and weaving for it to become a geotextile.
Under the system, cocofiber nets are laid on the eroded area and initially, grasses are planted. The coco fiber will hold the grasses that will prevent the land from eroding and being washed away during rainfall. After about three to six months, vegetation can already be seen. This will make the soil more stable.
Aside from application of coco nets, the district office is also building road slips protection structures in Capoocan, Leyte. Just this year, at least six road slips protection projects were completed.
