Doing it right the first time

www.DirectPushOnline.com Corporate 877-372-1937 In 1998, Geoprobe®, arguably the world leader in direct push technology, developed the Dual Tube soil sampling technology. The Dual Tube method of soil sampling allows for discrete and continuous soil sampling with NO slough, PERIOD. For collecting discrete and continuous soil samples, it is the most efficient direct push tooling method, with some limited drawbacks (it has greater sidewall friction than a standard MacroCore sampler and it is difficult to retrieve samples when “heave” inside the tool string is an issue)(see the Geoprobe® Tab on our website, Dual tube versus MacroCore for further details). Even though this method is available and is hands down the best method for collecting soil samples beyond 4 feet in depth, not all probe operators use it, and more importantly, not all consultants demand it.
