Steco Core Drilling Machine ( Petrol )

Extraction of concrete cores, achieved by rotary drilling using a diamond tipped hollow barrel, serve as a means of taking a sample of concrete which can then be used to determine various physical properties, but most commonly compressive strength.
Cores can generally be extracted from wherever access allows, and would include floor slabs, walls and columns. 10cm diameter cores, generally afford the minimum diameter required for a representative sample and require less reinstatement than larger diameter cores. 15cm diameter cores will generally give more representative samples than smaller diameters but require more reinstatement
