We have found that squeaky floors above a crawlspace or basement, are generally a result of some type of moisture problem. When there is a fluctuation in moisture content in the floor joists, they tend to swell and shrink. When the wood shrinks, it moves apart, causing the fasteners to become loose. This shrinkage effect can result in a gap to occur between the sub floor and the floor joist. The squeaking noise occurs as the fasteners and boards move against each other as weight is placed on them.
The basement or crawl space does not have to have a "water" problem for the moisture content to be too high. If you have a vented crawlspace, outside air that enters your crawlspace is full of humidity in the summer. In a basement, moisture will evaporate from the walls and from the floor.
The best solution to squeaky floors is to first address the moisture problem below the floor. In a crawlspace, it is recommended to encapsulate and condition the space so that the moisture content is consistent and low in the crawlspace. In the basement, it is recommended to have a good vapor barrier on the walls and a whole house dehumidifier installed.
As to repairing the squeaky areas of the floor, this can be simple and complex. Typically, screwing down the sub floor to the floor joists will eliminate the problem. It is best to add sub-floor glue during this process. If it is an area that cannot be screwed down from up above, there are specialty fasteners that can be used to draw the floor down to the joist. A simpler technique to the specialty fasteners is to attach a 2x4 to the side of the joists and screw at an angle up to the sub floor bringing it down tight against the joist. If the squeak is caused by two layers of subfloor rubbing against one another, then the bottom layer needs to be screwed to the top layer from underneath the floor. IMPORTANT: When you are screwing upwards from underneath, make sure your screw is not too long so you will prevent it from going through your hardwood floors or carpet.
As a general rule, the approach taken to remove the squeak is to remove the rub or gap out of the wood, and remove the moisture content in the air that is causing the rub. Otherwise, you will constantly be repairing squeaks in the floor as they continue to pop up from high humidity levels in the floor.

A sump pit hole was dug, and a 4"perforated corrugated pipe was placed in the trench running into the sump basin hole.
The sump basin was installed in the hole with the 4" tile draining the water from the trenches. The trenches were backfilled with an aggregate to prevent silting and clogging.
