Geosynthetic drainage boards are a type within the drainage board family. They are in block form, waterproof and water-retaining, commonly used in roof greening and indoor planting.

A lightweight panel made by heating and pressure forming high-density polyethylene (HDPE), which serves as a drainage channel with certain spatial support rigidity and also functions for water storage.

This board material boasts both water-retaining and water-draining capabilities. It features high spatial stiffness and superior compressive strength compared to similar products (which can be verified through on-site testing). It can withstand over 400Kpa of compressive load and also endure the end load caused by mechanical compaction during the backfilling process for the planting top deck.

Key Features:

Easy to install, maintain, and cost-effective.

2. High load-bearing and durability.

3. Rapidly expels excess water.

4. The water storage section can store some of the water.

5. Provides ample water and oxygen for plant growth.

6. Light weight with strong roof insulation and thermal preservation properties.
