    Geotextile in a water well to prevent sand intrusion.

    GeoEnvy Guy They soil around us is pretty much pure sand, we did put some rock in, but it is larger 1 to 2 inch chunks, we also made a "sock" for the pump. When we get into late dry season we will have the guys come and clean out the excess sand that has accumulated (we have to wait so the...

    Hello, I have a question regarding the use of geotextile in a well. We have a hand dug 30 inch X 14 foot well very near the coast, (50 meters) the soil is almost pure sand. We are getting a lot of sand in the filter (5 micron), so we are wondering if we were to use geotextile membrane if this...
