Corrugated black pipe is the “cheap” standard in the industry, but its internal ridges trap sediment, catch tree roots, and make it impossible to clean out with a snake. It also crushes easily under soil weight. At Basement Expert, we only use Solid-Wall Schedule 40 PVC for our drainage systems. PVC has a smooth interior that prevents clogs and is strong enough to last a lifetime. It is an “Engineering-Grade” material that ensures your drainage system actually works when you need it most.

Pro Note: While corrugated pipe relies on thin ridges for strength, Schedule 40 PVC utilizes a consistent wall thickness that resists root penetration and ground shifting, ensuring your French drain stays open and flowing for the life of the structure.
