Geodrain
Geodrain is a high-performance geocomposite drainage system designed to collect and discharge groundwater efficiently while reducing hydrostatic pressure on structures. It consists of a three-dimensional HDPE drainage core bonded to one or two layers of nonwoven geotextile, providing excellent drainage capacity, filtration, and long-term durability.
Geodrain is a lightweight and cost-effective alternative to traditional gravel drainage systems, making it ideal for modern civil engineering, waterproofing, and environmental projects.
Geodrain offers superior drainage performance while minimizing installation time and material costs.
Geodrain is widely used in various construction and infrastructure projects, including:
Applications of GeodrainSpecification | Description |
Core Material | High-Density Polyethylene (HDPE) |
Filter Layer | Nonwoven Polypropylene (PP) or Polyester (PET) Geotextile |
Core Thickness | 5–30 mm (Depending on Model) |
Water Flow Capacity | High |
Compressive Strength | Excellent |
Chemical Resistance | Excellent |
Biological Resistance | High |
Installation | Vertical & Horizontal |
Compared with conventional drainage systems, Geodrain provides numerous advantages:
The HDPE drainage core creates continuous flow channels that allow water to move quickly toward drainage outlets. The attached nonwoven geotextile acts as a filter, preventing soil particles from entering the drainage core while maintaining excellent water flow.
This combination ensures efficient drainage without clogging, even under high loads.

Lightweight | Heavy |
Easy to transport | Expensive transportation |
Fast installation | Labor-intensive |
High drainage efficiency | Variable performance |
Space-saving | Requires thick gravel layers |
Long service life | Higher maintenance requirements |
Selecting the appropriate Geodrain depends on factors such as water flow requirements, compressive loads, soil conditions, and project specifications. Our experts can help you choose the most suitable Geodrain solution for your waterproofing and drainage project.

Geo Block is a cellular geosynthetic solution for soil stabilization, erosion control, slope protection, road reinforcement, embankments, and drainage channels. Its three-dimensional structure confines soil and aggregate, helping improve ground stability, load distribution, and resistance to erosion. Geo Block can also be combined with geotextile and other geosynthetics to create an efficient ground reinforcement system for different construction and civil engineering projects.
Geotube is a high-strength geotextile dewatering system designed to efficiently separate water from sludge, sediment, and dredged materials. Ideal for wastewater treatment, dredging, industrial sludge management, and environmental projects, Geotube helps reduce material volume and simplify handling, transportation, and disposal.
GeoBag is an engineered geotextile dewatering and containment system designed for managing wastewater sludge, dredged sediment, industrial slurry, and other water-rich materials. It allows excess water to drain through the geotextile while retaining solid particles, helping reduce material volume and simplify handling, transportation, and disposal. GeoBag selection depends on factors such as tensile strength, permeability, apparent opening size, puncture resistance, dimensions, material characteristics, and site conditions.
