Composite waterproof drainage board, also known as three-dimensional composite drainage mesh and drainage grid, is a new type of geosynthetic drainage material. Made from high-density polyethylene (HDPE) and processed through a special extrusion molding process.

Features:

High drainage capacity (equivalent to one meter of gravel drainage).

2. High tensile strength.

3. Reduce the likelihood of geotextile embedding into the core mesh, ensuring long-term stable drainage.

4. Capable of withstanding long-term high-pressure loads (can withstand approximately 3,000 kN of compressive load).

5. Corrosion-resistant, acid and alkali-resistant, with a long service life.

6. Easy construction, reduced project duration, and cost savings.

Composite drainage boards are used in projects such as soft soil treatment, roadbed reinforcement, slope protection, abutment strengthening, coastal slope protection, and reservoir bottom reinforcement.
