Trench drain systems are either straight/neutral or pre-sloped. There are several configurations that can be used to achieve a slope. Some systems offer channels that have built-in slopes to quickly divert runoff. Straight channels can be used to create either a non-sloped run or a cascade slope by using channels that are consecutively deeper and connecting them with special couplers to create a step-down effect. A mixed slope is a combination of sloped and straight channels for a smoother step-down effect.  Need help planning your next project? Call our experts at 610-638-1221 or request info today.
