Crawlspace French drain and sump pump install for water in the Crawlspace

Water problems in your crawlspace? You may just need a French drain, sump pump, vapor barrier, and dehumidifier.  In this video,  I show all the steps in the process to go from water problems to pump in place. The next step is the vapor barrier. I'll have another video for the rest of the job.Show more

I dig the ditch, pick up gravel at the landscaping rock place,  install the corrugated perforated 4 inch drainage pipe, cover it all with gravel and install my new sump pump.

Under the pipe, I use 3/8 inch clean gravel to make the bottom nice and smooth and over it, I use 3/4 inch clean rock.

It took me about 50+ man hours and I spent 30 hrs under the house digging the trench.

The trench slopes downhill 1 inch every 8 feet.
