Drilled Wells

Drilled wells are either designed by cable tool (percussion) or by rotary-drilling machines. Drilled wells penetrating unconsolidated material include casing installation and a screen to prevent sediment inflow and collapse. We can dig over 1,000 feet deep. ‚ÄčThe area around the casing must be lined with grouting material of either tidy cement or bentonite clay to prevent contamination from the outside of the casing by water draining from the surface downwards.
