Liquefaction countermeasure method "New Pola Hole PROTECT Method"
Prevents lifting without damaging the manhole!
The "New Pola Hall PROTECT Method" is a liquefaction countermeasure technique that protects sewage and stormwater manholes with permeable manholes and backfills them with crushed stone. Our permeable concrete has a permeability coefficient of K=1.0 cm/sec or higher, allowing for the instantaneous collection of pore water pressure caused by liquefaction through the permeable manholes and its dispersion through crushed stone. 【Features】 ■ Effective for "rainwater infiltration" and "pressure infiltration" ■ Maintains permeability and breathability ■ Can be utilized as existing drainage ditches ■ Prevents uplift without damaging the manholes *For more details, please download the PDF or feel free to contact us.
