Concrete Piles

Marine Master Technology, with the largest production capacity in the country and a nationwide supply network, offers the highest quality and customer value.

PHC (Pretensioned Spun High-Strength Concrete) Piles

"Concrete piles are essential foundation building materials that transmit the load of a structure to the ground. PHC (Pretensioned Spun High-Strength Concrete) piles are high-strength concrete piles with a compressive strength of 78.5MPa (800kgf/cm²) or higher, made using the prestressing method, which applies centrifugal force.

Distinctive features of PHC piles

Marine Master Technology prioritizes durability and occupant safety

in construction with our premium brand Hypile.

Marine Master Technologyinitiated research on PHC piles through a technical partnership with Japan's Nippon Hume, becoming the first in Korea to do so in 1991. Leveraging advanced manufacturing technology, we successfully commercialized PHC piles from 1992. In addition, we obtained KSF 4306 certification in 1992 and ISO 9001 certification in 1996. Keeping pace with internationalization, we became the first in the industry to acquire JIS (Japanese Industrial Standard) certification in 2001.

Ultra-High-Strength Piles

Ultra-High-Strength Piles represent the evolution of high-strength concrete piles, increasing the allowable axial load capacity of the piles. By raising the compressive strength from the previous 78.5MPa to 110MPa, these piles economically enhance the allowable axial load capacity by 145% to 147% (Type A)

Large-Diameter Piles

Above Ø700mm PHC piles are referred to as large-diameter piles. They are used in structures that require high bearing capacity, primarily in applications such as earthquake-resistant design for high-rise buildings, large-scale apartments, extensive road and railway bridges, and other structures.

Earth Retaining Pile (Hypile-W)

Using PHC PILE as wall material increases the stiffness of the wall and simplifies construction through mechanization, resulting in cost savings and reduced construction time for visible structure projects. It is an environmentally friendly "Hypile" wall method with no soil contamination.
