PVC sheet piles over sandbags mulled-A A +A
Sunday, September 1, 2013
CITY OF SAN FERNANDO -- Governor Lilia Pineda and the Capitol’s engineers are looking at Polyvinyl Chloride (PVC) sheet piles in lieu of sandbags as protective measures in dikes, riverbanks and other flood mitigating infrastructure.
“This could be the solution we are looking for over palliative and more expensive sandbagging,” said the governor over the weekend, when a private sector proponent discussed the merits of PVC sheet piling.
The PVC sheet piles have been tested and are in use in countries like the US, Europe, and most recently in Taiwan.
It will be used in the Philippines -- particularly in Pampanga -- for the first time.
In a ballpark estimate, the proponent said that a one-meter long, three-meter high PVC sheet pile could cost about P29,000, exclusive of installation.
The PVC sheet is non-porous like concrete, does not corrode like steel, and is easy to transport and install, the proponent added.
Governor Pineda said, however, that Capitol’s engineers and the private sector proponent’s team will re-study and re-evaluate Pampanga’s terrain and soil composition in various riverbanks where the PVC sheet piles would be viable and effective.
The trial area proposed by the governor for the PVC sheet piling will be the 40-meter breach at a dike along San Jose in Guagua town.
