Polymer concrete channel with grates

Polymer concrete drainage channals fastened by grate locks, supporting other parts of the composition as a typical polymer concr A typical polymer concrete trench drainer contains a channel body, grates, grate locks, a catch basin, an end plate and an outlet.Because of the height difference between the trench channel body and the catch basin, this system not only collects surface rainwater rapidly, but also prevents dirt blocking the channel body. When rainwater enters the catch basin, the dirt precipitatation will be collected in a dirt collecor to facilitate post-system maintenance. Rainwater will be flushed through PVC pipes into the municipal pipe network.
