Length of time to dry crawlspace?

Hi all,

For the last 10 years the main sewer line pipes under the house have been leaking water in to the crawlspace. It was muddy in the crawl space naturally. 8 months ago we installed new pipes. Now the soil is very damp unsteady of muddy. Does it usually take this long for the crawls space dirt to loose the moisture? House is located in dry southern California. I have no fans attached to the crawlspace vents yet. I am thinking about getting some. Thoughts?

There is no secret formula. It would depend on soil conditions, how much ventalation, if there's more moisture getting in because of no gutters, no french drain, no slope to the grade around the foundation, mulch piled up againt the foundation, water table, amount of rain fall, ECT.

8 months and it is still damp under there?

You still have a problem somewhere.

If he has the same soil I do....sounds about right......also depends on the air circulation....

I had a damp/wet crawl space this past winter....combination of rains and no roof.....

I took a fan, put it over the access hole and turned it on.....ran for a few days....much dryer. Turned if off....couple days later....damp again....so I ran it some more....

It's fine now.

We have that horrible adobe clay soil....holds water real well....
Even if you are on the right track, you will still get run over if you just sit there.
