1. This machine can be installed on the original drainage board equipment for seamless integration, enabling the self-adhesive drainage board coating function. The machine is easy to operate and highly automated.

2. Equipped with a wear-resistant alloy steel coating head, the coating control accuracy and service life are greatly improved. Drainage boards are mainly used in underground engineering roof or rooftop greening. Compared with conventional processes, the composite of drainage board and geotextile integrates multiple functions such as drainage, waterproofing, breathability, moisture retention, and root barrier.
