Perforated drain-pipe expands in length from 2 to 8-feet - compatible with most traditional 3-inch and 4-inch corrugated pipe and 4-inch pvc
The perforations drain the area along the full length of the pipe to discharge at the end
Exceeds the following astm standards - flex-drain outperforms the leading brand of corrugated pipe with brittleness, stiffness, and joint integrity
Engineered to outperform - Installs faster, requires 1/5th the storage and transport space, and perforated pipe has 14% better flow rate
Advanced design for superior performance - outperforms in freeze and thaw conditions, also has 30-percent higher load-bearing rating from our patented peak and valley design
