Drainage Board for Roof Garden

Why are drainage boards suitable for use in roof gardens?

Roof gardens are afraid of excessive weight, water accumulation, water leakage, plant root rot, and root damage to the waterproof layer. HDPE drainage boards can solve all these problems, so they are essential materials for roof gardens.

◆HDPE drain board is extremely lightweight, the roof can bear the load and drain water quickly without causing water accumulation. 

◆It protects the roof waterproof layer from being punctured or corroded.

The planting soil has acidic or alkaline corrosiveness, and the plant roots will penetrate downwards.

The HDPE drainage board is resistant to acid and alkali, anti-aging, and resistant to root penetration. It separates the soil layer and the waterproof layer, preventing corrosion and root damage to the waterproof layer, thereby extending the lifespan of the roof waterproofing.

◆It allows for good air circulation and helps prevent root rot. 

◆It is resistant to root penetration and does not get corroded. 

◆The dimple hdpe drainage board can store some rainwater, saving watering efforts and making it drought-resistant. 

◆Simple construction, saves money and shortens the construction period
