Direct Push Drilling – The Ideal Method For Environmental Soil Sampling

Direct Push Drilling

What is Direct Push Technology (DPT) and Direct Push Drilling (DPD)? DPD Technology allows for a wide variety of direct push tooling and instrumentation to be pushed into the ground using the static weight of the rig, hydraulic down pressure, and rapid hydraulic hammering. Direct Push Tooling is used to perform soil, soil gas, and groundwater sampling, soil remediation, and geotechnical sampling testing. Compared to conventional drilling, DPD is less labor intensive, generates less drill cuttings and offers quicker setup time.


Direct push technology became more popular in the 1990's in response to a greater need to assess sites quickly and in a more cost effective manor. DPT is applicable in unconsolidated sediments and works best for shallow depths (less than 100 feet), but may be able to go deeper depending on site conditions.


Direct Push Drilling provides several benefits to meet your sampling needs. Compared to conventional drilling, DPD is less labor intensive and more cost effective. The technology allows for a more competitive pricing option and a more accurate service. This method offers an alternative to traditional sampling such as hollow stem auguring with split spoon sampling. Some advantages include the smaller size of the rigs, which allows the rigs to access hard to reach areas for sampling in spaces that would be impossible for larger rags. This method also produces fewer cuttings allowing for cheaper and easier disposal of material. The speed and mobility advantages of DPT soil sampling may allow a more complete and accurate investigation of the sites geology and make up. Similarly, when investigating ground water, the speed of investigation and a lack of a need for well materials allow for a more thorough evaluation of the site.


These applications and benefits are just some of the key examples of how direct push technology and drilling is the ideal method for environmental soil and groundwater sampling.
