1. Product Overview

Plastic dimple drainage board is a geosynthetic material made from high-density polyethylene (HDPE) or polypropylene (PP), featuring a dimpled structure for enhanced water drainage and load-bearing capacity. The dimples create air gaps for effective drainage, protecting foundations, basements, and roofs from water accumulation and damage. This product is widely used in waterproofing systems for green roofs, retaining walls, and civil engineering projects.

2. Product Features

• Efficient Drainage System: Dimpled surface ensures fast and efficient water drainage.
• High Strength and Durability: Made from HDPE/PP, resistant to compression, punctures, and environmental stresses.
• Waterproofing and Protection: Prevents water seepage and protects structures from moisture-related damage.
• Eco-Friendly Material: Non-toxic, recyclable, and safe for environmental applications.
• Easy Installation: Lightweight and flexible design simplifies handling and installation.
