Composite drainage board (also known as three-dimensional composite drainage network or drainage grid) is a new type of drainage geotextile. Made from high-density polyethylene (HDPE) as raw material and processed through a special extrusion molding process, it has a three-layer special structure. The middle reinforcement has high rigidity and is arranged longitudinally to form a drainage channel. The cross arranged reinforcement forms a support to prevent the geotextile from being embedded in the drainage channel, and can maintain high drainage performance even under high loads. The composite use of double-sided adhesive permeable geotextile has the comprehensive performance of "filtration drainage breathability protection" and is currently the most ideal drainage material.

1. Composite drainage boards can be applied in soft foundation treatment, roadbed reinforcement, slope protection, bridge abutment reinforcement, coastal slope protection, and reservoir bottom reinforcement projects.
2. Composite drainage boards can also be applied to underground garage roof planting, roof planting, underground sidewall protection, drainage, bottom plate drainage, tunnel waterproofing and drainage, highway slope protection, saline alkali land, desert planting, and artificial lakes.
3. The application function of composite drainage boards can be bent and constructed at will, quickly draining the static water of the waterproof layer and HDPE geotextile water accumulation, timely reducing the load on the main structure, protecting the waterproof layer and structure, and avoiding damage to the waterproof layer by soil backfilling, plant root thorns, acid and alkali, underground insects, and microorganisms. Combined with the use of waterproof layer, it plays a dual waterproof and anti-seepage role, isolating gas and preventing oxidation, greatly improving the service life of the waterproof system.
Composite drainage boards have many functions such as isolating hot air, soft foundation treatment, and slope protection. Composite drainage boards can be applied in artificial lakes, highway slope protection, and other areas, and their application range is quite extensive.
