Yes this is very possible....I have seen it. By using a high pressure probe (1/2" in dia.)the injected oxidant slurry can be hand pushed down to about 12 feet through a rather hard clay material. I will get a contact with a Company that provides this service and send you a link.....

Gentlemen, I just finished helping my father with this exact problem. This is a huge legal issue not doubt. Unfortuneatley while you fight this battle with the developer and city engineers years may pass along with thousands of headaches, man hours, and time (which as we all know time is...

I have done the rid-ex thing as well on a rental and I know for a fact that the people renting aren't follwing Cosimo's guidelines....which any sensible homeowner should follow. So far so good, I really haven't had problems. If it is a pyschological thing I am not looking for therapy to fix...

ctmt is right on track, local agencies are your best resource. One word of caution for you before you consider punching holes. Sometimes in the most unlikely of places there are natual springs that exist. I dealt with a land parcel that behaved like the one you have mentioned and made the...
