Washboring is another method of drilling we provide used in certain situations were soils are becoming difficult. At times when sampling is not needed, it can be the quicker option for getting to depth. With the use of our moyno pump, water is forced down the drill stem at high pressure, to keep the bit from “burning up” and to flush away cuttings.
Through soils such as sands with a strong hydrostatic water table (blow back) or even soft clays, the water pressure forms the borehole perfectly. It is also useful in boulder till formations where large solid boulders are encountered during the drilling process. Wash boring is also functional with any type of soil sampling, at the desired depth when needed.
