High Capacity Drainage Solutions

Trench Era represents several series of high-capacity trench drain systems designed to provide versatility to project designers as well as contractors. They consist of three main groups including frame and rail, EPS foam forms (coming soon) and prefabricated channels.


The first in this family of products is the Fast Frame™ FF Series which is a robust frame and grate system intended for jobs in which the channel is to be fabricated on-site. This system provides a standard hardware pack with the exception of the supporting spanner bar that varies in size depending upon the width of the system.

FF Series includes your choice of stainless steel or galvanized rails in lengths of 4′, 6′ or 8′ sections. These rails accept grates that are 1-1/2″ thick. The width of the system is dependent upon how wide the selected grate is. In general, the width selection is 8″, 10″, 12″, 14″ or 17″. Appropriately sized spanner bars are placed in 2′ increments with end plates available to complete each drainage run. This requires light assembly providing the advantage of significantly reduced shipping expense. Contractors are responsible for forming the trench and creating the proper depth and any slope that may be required for the project. A jig is available for purchase to facilitate an effective concrete pour or we can provide plans and a material list for on-site jig fabrication.

TDS’s FP1200 Series™ high volume trench drain is the ideal solution for high-volume flow situations such as airports, roadways and seaports. Designed with the installer in mind, this revolutionary design incorporates full 360° interlocks to minimize installation time.

The drain is 12″ wide and comes in both 4′ and 8′ lengths for maximum flexibility. Flow rates of up to 6700 GPM can be achieved over 120′ of continuous 1% slope. Grates are available to meet DIN Load Classes C through F. Three separate grate options are available that exceed FAA AC150/5320 loading criteria for airports, and all grates meet or exceed AASHTO M-306 loading criteria for roadways.

Installation Benefits

The FP1200 Series™ Trench Drain System is designed for fast installation. By utilizing 96-inch long sections and prefabricated turn and Tees; the need for field modifications before concrete placement is eliminated. 360-degree interlocks mean that almost no time is spent ensuring proper alignment. This leads to a much faster installation time than other systems meaning there is a lower final cost and better value to the end user.
