Rainwater infiltration product Honey Hole installation example

Diverse lineup! Infiltration wells that are effective for securing groundwater sources and preventing river flooding.

The rainwater infiltration product "Hani Hall" is designed to effectively retain and slowly return rainwater to the underground, ensuring a plentiful supply of rainwater. In recent years, the reduction of green spaces due to land development and road paving has caused rainwater, which used to flow slowly, to suddenly rush into rivers, leading to ground subsidence and depletion. By installing this product on roads and ditches, we can eliminate these issues and promote the securing of groundwater sources, prevention of river flooding, prevention of ground subsidence, and the natural recovery of urban ecosystems. [Installation Examples] - Building rainwater downspouts - Areas without drainage facilities in parking lots or narrow roads - Individual residential rainwater downspouts - On-site drainage park drinking fountains - Ditches, etc. *For more details, please refer to the PDF materials or feel free to contact us.

Pipe narrowing "Crocodile Grating" trench cover U-shaped ditch

Just placing it on top of the U-shaped drain makes the surface level of the road and the top of the grating almost the same.

Pipe Strainer "Crocodile Grating" Drain Cover U-shaped Channel is designed so that by welding angles to both ends of the grating and simply placing it on top of the U-shaped channel, the surface level of the road and the top surface of the grating are almost the same. With fine non-slip features, the bearing bar uses a T-shaped (T-BAR) design. The T-bar, which is less prone to clogging, allows stones and debris that pass through the top to fall into the channel without getting stuck along the way. This makes cleaning and maintenance easy and gives a clean appearance. Additionally, there are three rows of NS protrusions on the top of a single T-BAR steel material, significantly enhancing the non-slip effect compared to conventional products. It is an ideal product for places where many people gather, such as parks, sports facilities, and public spaces. For more details, please contact us or download the catalog.
