Seren Construction Co., Ltd. is a construction company specializing in ground improvement and temporary shoring, located in Cheongju, Chungbuk. We specialize in trenchless mechanical excavation, focusing on steel pipe jacking and earth retaining temporary shoring construction.

"Seren Construction Co., Ltd. specializes in steel pipe jacking and temporary shoring construction. In particular, by introducing the GEONEX of Finland jacking machine, which is the first in Korea capable of working on bedrock, boulders, and soil, we safely perform construction without accidents in sections where manual excavation is impossible due to face collapse or river water inflow."

Business Areas

• Mechanical steel pipe jacking and jacking construction: Using special jacking equipment, we perform trenchless excavation under roads and obstacles to push in steel pipes. We perform precise and safe construction tailored to various ground conditions such as bedrock, boulders, and soil.
• Temporary shoring construction: We install temporary shoring walls and support structures to prevent the collapse of surrounding ground and ensure safety during underground excavation work. We support the safety of subsequent processes through stable construction tailored to ground characteristics.

Products

• GeoNex mechanical jacking method: This is an advanced trenchless construction technology that can quickly excavate and push through soil, boulders, and extremely hard rock ground without changing the head. Safe excavation is possible even in sections with risks of river water inflow or face collapse.
• Temporary shoring construction service: This is a customized temporary shoring design and installation service that supports the ground and maintains the stability of the excavation surface before installing underground structures.

Special Notes

• Introduction of Korea's first advanced GeoNex equipment: By introducing advanced mechanical jacking equipment from GeoNex in Finland, we safely and quickly penetrate high-difficulty ground sections where manual excavation is difficult.
• Capability for all soil types and safe construction: Continuous construction is possible without equipment changes in a wide range of ground conditions, from soft ground to extremely hard rock sections, ensuring shortened construction periods and high on-site safety.
