Prefabricated Vertical Drain (PVD)
"LAND DRAIN" is the water draining material (Prefabricated Vertical Drain, PVD) for soft supporting soil improvement. It has been applied in a variety of civil engineering sites such as earth filling for harbor, reclamation, road, railway and airport.
Based on accumulated R&D, it will help many kinds of development works with its low cost and stable work performance.
Our factory is located in South Korea and has been produced this item over 20 years.
"LAND DRAIN" is highly economical.
It can save the cost of works up to by 20-50%, compared to sand drain, given that the same water draining performance is attained.
"LAND DRAIN" is speedy for driving.
As the Drain Boards are light weight and easy for handling, they can be driven quickly into the subsoil. With a simple driving system weighting 3 to 5 tons, Drain Boards covering a length of about max. 25,000M can be driven per a day.
"LAND DRAIN" is highly suitable for even very weak soil.
Drain Boards possess a permeability that is practically the same even if the soil pressure is 6kg/cm2, a pressure corresponding to a depth of about 50 meters.
