A quick overview of the Lost Cone Drilling Set and how to operate.

The Lost Cone Drilling Set is a fast and efficient way to install a 1 inch monitoring well when there is no need to take a sample. It is particularly relevant for stony soils or gravels. A specially designed cone is mechanically hammered into the soil to produce a very straight bore hole. Using this equipment makes it easier to reach depths up to 10m and the friction on extracting the casing is reduced. After drilling the 'lost' cone is left in the soil. This has no environmental impact as the construction material of the cone is found in soils naturally.

Principle of operation:

A hollow casing is fitted with a lost point and hammered, meter by meter, into the ground until the installation depth for the well is reached. Your choice of 1" well is then lowered through the casing and the casing retrieved to leave the well in place. The well can then be sampled and purged in the usual way.

Benefits:

Ideal for inserting groundwater monitoring wells in stony soils and gravels
Non-toxic, environmentally neutral lost cone point that can safely be left in the soil
A fast and efficient drilling method
Available as a complete set
Easy to transport
The special shape of the lost cone ensures there is less friction when the casing is inserted and extracted again
Ideal and safe for making holes for the installation of explosives in mining.
