Crawl Space Drainage
Crawl spaces have many challenges because rainwater and groundwater can enter easily through vents and cracks and remain there. A flooded crawl space can cause many issues, especially mold and mildew, which is a severe health hazard.
In the Charlotte area, the natural topography directs water into crawl spaces and under foundation walls, increasing the risk of a flooded crawl space and soil erosion.
If your crawl space has standing water, Dry Otter provides premium crawl space drainage and repair, and we offer free inspections.

Why do I need drainage in my crawlspace?
Many crawl spaces have groundwater seeping in. When this happens, a crawl space drainage system of French drains is necessary to collect the water and direct it out of the crawlspace via a sump pump or gravity-fed exit system.
A crawl space drainage system will keep your crawl space dry and help reduce structural problems due to soil erosion.
What is a French drain?
A French drain consists of a ditch or channel dug around the crawlspace’s inside perimeter with a pitch or slope with a perforated pipe and gravel on top.
The drain directs water toward the sump pump or a special place for the water to exit by gravity.
Why are they called French drains?
How is a French drain installed in a crawl space?
- A trench is dug along the interior perimeter walls of the crawlspace. It should be sloped so water will drain towards the designated exit.
- A perforated pipe is inserted into the trench.
- The pipe is then covered with gravel. This prevents the line from clogging.
- The pipe is connected to a sump pump or gravity exit.
What is the warranty on crawl space drainage?
Dry Otter offers a lifetime warranty on crawl space drainage. Sump pump systems carry a manufacturer’s warranty. We do recommend annual maintenance.

In today's business environment it's so rare to find a reputable company that stands behind their installations. Dry Otter is the real deal! I had a problem with a crawlspace dehumidifier they installed years ago. Dry Otter sent a tech out the same day, diagnosed the problem and ordered the new part . Three days later they came back and installed a new control board, covered under warranty. Their tech Daniel Soto even called the following day to make sure everything was working to my satisfaction.
