Three-dimensional composite drainage board

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

Features:

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

High tensile strength.

3. Minimize the chance of geotextile embedding in the core, ensuring long-term stable drainage.

4. Capable of withstanding long-term high-pressure loads (can bear approximately 3,000 Ka of compressive loads).

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

6. Easy construction, shortened project timeline, and cost reduction.

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