Protect Against Water Damage With a Corrugated Drainpipe


A corrugated drainpipe is a simple solution to divert water away from your home and protect your foundation, basement and yard from damage. You can find corrugated plastic pipes in a range of inner and outer diameters and lengths to fit the unique volume and space demands of your exterior spaces. Select from white or black piping in either polyethylene or polypropylene to blend seamlessly with your overall drainage system.


Some of our corrugated plastic pipes are designed specifically for driveways or culverts. Other corrugated, perforated drainage pipes can be used in landscape drainage applications. French drainpipes remove groundwater from soil around your house and yard, without the need to haul and place large amounts of heavy rock or gravel.


We offer many corrugated drainage pipes that are flexible and much easier to install than other types of piping. If you want to learn more about keeping your yard and home dry and damage-free, check out our guide — How to Solve Simple Drainage Problems.


Frequently Asked Questions


Q: How do you bury corrugated drainpipe?

A: Dig a trench for the drainage pipe about 1-1/2 to 2 feet deep and 8 to 9 inches wide. The trench needs to be flat with about 1 inch of drop for every 10 feet all the way to the drainage output area. Place pieces of water-permeable landscape fabric in the trench, followed by about 3 inches of coarse gravel. Lay the pipe with drainage holes facing downward. Connect the pipe to the catch basin that collects the water. Test the flow and adjust as needed. Cover the pipe with 3 inches of gravel. Fold the landscape fabric over the pipe and bury the pipe with soil.


Q: Do I need gravel when installing corrugated drainpipe?

A: If you’re installing perforated corrugated drainpipe, you need to lay it in a trench lined with several inches of gravel. The gravel allows water to drain freely from the small holes in the pipe and helps prevent clogging. Add gravel around and on top of the pipe, as well, before backfilling the trench with soil.


Q: Why are corrugated pipes used for drainage pipe?

A: Corrugated pipe is relatively lightweight and flexible, making it much easier for the do-it-yourselfer to work with than rigid pipe. For many simple drainage applications around a home landscape, this ease of use outweighs the value of the increased durability that rigid pipe offers.
