DAEHAN i.m. offers Verti-Drain®, a pocket-style prefabricated vertical drain designed for soft ground improvement. With its durable polypropylene core and specialized nonwoven filter jacket, it accelerates soil consolidation, minimizes settlement risks, and ensures reliable long-term performance for infrastructure and land development projects.
What Is a Prefabricated Vertical Drain?
Prefabricated vertical drains (PVDs), also known as wick drains, are installed in soft, saturated soils to speed up pore water dissipation and soil consolidation. By creating additional drainage paths, PVDs reduce settlement time and make soft ground more suitable for large-scale construction projects.
Verti-Drain®: A Reliable Prefabricated Vertical Drain Solution
Verti-Drain® is a pocket-style prefabricated vertical drain manufactured using a mechanically strong PP core and a nonwoven filter jacket. The product is engineered for PVD applications where drainage performance, installation durability, and long-term material stability are important.
The quality of Verti-Drain® is supported by multiple certifications and quality marks, including ISO 9001, CE, Q-mark, R-mark, and Eco-Label.
Its combination of a strong core and specialized filter jacket provides a balanced structure for soft ground improvement applications.
Key Features of Verti-Drain®
- Mechanically strong PP core: Provides structural strength for demanding installation conditions.
- Specialized nonwoven filter jacket: Designed for prefabricated vertical drain applications.
- Suitable AOS filter material: Helps reduce the potential for long-term filter clogging in soft soil improvement applications.

- Multiple certifications and quality marks: Includes ISO 9001, CE, Q-mark, R-mark, and Eco-Label.
How Does a Prefabricated Vertical Drain Work?
The basic purpose of a PVD is to accelerate the consolidation of saturated soft soil.
When a load is applied to soft, water-saturated ground, excess pore water pressure can develop. Because soft clay generally has low permeability, the water may take a considerable amount of time to escape naturally. This can delay consolidation and settlement.
A prefabricated vertical drain provides a shorter and more efficient drainage path.
Why Use PVD Technology for Soft Ground Improvement?
The primary advantage of a prefabricated vertical drain system is its ability to accelerate the consolidation of soft ground.
For large construction projects, natural consolidation can require extended periods. Accelerating this process can help reduce the time required for ground improvement and support more efficient project scheduling.
Applications of Verti-Drain®
Verti-Drain® can be applied to a wide range of infrastructure, industrial, reclamation, and land development projects where acceleration of soft ground consolidation is required.
