FRP drainage well

FRP drainage basins are products designed for the collection and drainage of water on bridge surfaces. They are listed in "Construction Prices" as "FRP drainage basins for bridges."

The upper part is made of steel grating, while the lower part is made of FRP, making it lighter than cast iron and improving durability. Our unique waterproof layer joint makes it easy to connect to the waterproofing of the deck, and by adopting the new non-slip specification "D Grip" with a BPN value of around 40, we contribute to the durability and safety of the bridge. We also have specifications available for PC deck slabs, making it suitable for a wide range of bridge types, regardless of whether it is new construction or renovation. 【Water Collection】 A wide joint for the waterproof layer is provided in the "lower part" to reliably collect infiltrated water on the waterproof layer. 【Durability】 The "lower part" is made of FRP, which has excellent corrosion resistance, eliminating concerns about corrosion. We have conducted a load test of 100 kN and confirmed that it does not break. 【Workability】 Height adjustment bolts allow for height and angle adjustments of the cover part.
