The POLYCAST® 900 Series is the nations premier transportation industry trench drain system. With over 25 years of service, this system has proven itself time and time again as the industry standard.
The 900 Series is designed for heavy traffic areas such as airports and roadways. Sloping .65 percent at 6.25″ wide (OD), the transportation-rated drainage system carries up to 470 GPM – more than comparable systems from other manufacturers. The trench system’s channels come in 48″ and 24″ lengths, making for easier installations that involve fewer pieces.
Polycast 900 Series’ polymer concrete channel body makes it resistant to salt, oils, acids and alkalis found in high traffic roadways and airports. The system features interlocking tongue-and-groove channels and adjustable installation chairs for a secure concrete pour.
