precast surface drainage channel with slot cover

The trench drain can be made of different materials, such as plastic and concrete. Resin concrete is often used due to its strong structure and chemical resistance, which makes it a major advantage for residential applications. Assuming that the green plant worker is fertilizing the lawn, some of which will enter the drain, so there is no need to worry about the resin material cracking due to its characteristics. That being said, we strongly recommend limiting the amount of chemicals that are ultimately used in the excretion system. Runoff will eventually pollute larger waters such as lakes, rivers or streams.
