Concrete coring involves the use of a drill to remove a cylinder of concrete. It's typically used when precise, circular cuts are needed for utility installations or to sample concrete for testing.
Remember the saying "measure twice, cut once." Concrete scanning identifies embedded objects in concrete, such as utility lines, rebar, or conduits. Cutting and coring can then be planned and safely completed, avoiding costly damages.
It's typically not recommended to core without anchoring, as the vibrations from the drill can cause the equipment to move, leading to inaccurate cuts or safety hazards.
Coring through rebar can weaken the structural integrity of the concrete and may lead to cracks. Therefore, it's essential to perform a concrete scan before coring to avoid cutting through rebar.
Line drilling involves creating a series of closely spaced core holes to create openings in walls or slabs where sawing isn't feasible. It's an effective technique for controlled demolition or when dealing with thick, reinforced concrete.
Slabsawing involves cutting through concrete slabs using a special saw. Before slabsawing, the concrete is scanned so that no embedded objects are hit during the process.
Coring through rebar can weaken the structural integrity of the concrete and may lead to cracks. Therefore, it's essential to perform a concrete scan before coring to avoid cutting through rebar.
Expansion joints are cut into concrete to allow for expansion and contraction caused by temperature changes. These cuts help prevent cracking and should be made by a professional to ensure they're correctly placed and sized.
