Drain channels, also known as linear drains, serve a important role in managing surface water and ensuring proper drainage in various applications or areas. Here are some key uses: 

1. Prevent Flooding: They collect and channel surface water away from areas prone to pooling, such as driveways, patios, and parking lots, reducing the risk of flooding.

2. Protect Structures: By diverting water, drain channels safeguard buildings, garages, and basements from water damage caused by water infiltration.

3. Enhance Safety: By preventing water accumulation on walkways and roads, they reduce slip hazards and improve safety for pedestrians and vehicles.

4. Erosion Control: Drain channels help manage water runoff, minimizing erosion of soil and landscaping.

5. Efficient Drainage for Large Surfaces: They are ideal for areas with extensive hardscapes, like pool decks, sports facilities, and industrial zones, ensuring water doesn’t accumulate.
