Drilled Mini Piles are used when underground obstructions such as rocks, boulders and mass concrete are expected, to penetrate hard strata to form a pile, or rock socket into a rock layer or bedrock.
A Down The-Hole Hammer Drill or DTH Hammer is a pneumatically operated, self contained recipricating hammer designed to be screwed on the bottom of a drill string.
Powered by high volume air compressor, the fast hammer action breaks hard rock into small flakes and dust and is blown clear by the air exhaust from the DTH hammer.
DTH Drilling is one of the fastest ways to drill into hard rock.
Drilled Mini Piles are installed by drilling into the ground with a the DTH hammer and drill bit to a specified depth.
Once the drilling string is retracted from the bored hole it is filled with grout or concrete and a single bar or reinforcing cage is inserted.
