Drainboard for Terrace Garden Waterproofing

A drainboard for terrace garden waterproofing is a lightweight, plastic mat with a grid-like structure on the underside. It sits between the waterproofing membrane and the growing medium (soil) in a terrace garden.

Advantages:

• Improved Drainage: The grid structure allows excess water to drain away from the plant roots, preventing root rot and waterlogging. This is crucial for healthy plant growth, especially during heavy rainfall or overwatering.

• Protection of Waterproofing Membrane: The drainboard acts as a buffer between the soil and the waterproofing layer, protecting it from punctures caused by roots or sharp objects in the potting mix.

• Aeration: The air pockets created by the grid structure allow for better air circulation around the plant roots, promoting healthy root development.

• Weight Reduction: Drainboards are lightweight compared to traditional gravel drainage layers, reducing the overall weight load on the terrace structure.

• Easier Installation: Drainboards are lightweight and easy to cut and shape, allowing for faster and more flexible installation compared to gravel or other drainage methods.
