Conventional catch basins were constructed to protrude slab foams towards the bottom after perforation, resulting in loss of materials and higher costs of installation. By contrast, the recessed type catch basin(YS-41, 42) developed newly is easy to install without need for perforation of plywood, reducing the loss of materials, increasing the ease of construction, and providing excellent cost-effectiveness. New catch basin products developed for the first time in Korea are unveiled below.

• YS-39□ 250 X 250 X Φ150 X 400H
• YS-40□ 250 X 250 X Φ150 X 400H
• YS-41□ 250 X 250 X Φ150
• YS-42□ 250 X 500 X Φ150

The grating is separated and rotated to facilitate cleaning and to prevent theft.

• YS-411□ 250 X 250 X Φ150
• YS-421□ 250 X 500 X Φ150

It prevents damage to bridges by guiding the stormwater that penetrates into fine gaps between the catch basin and concrete.
