Wall sawing utilizes circular diamond blades mounted on a rigid track system to make vertical or horizontal cuts in concrete or masonry walls. Wall sawing is typically used to cut doorway, windows and HVAC openings. This method of cutting can be used for up to 24" thick walls or floors, or up to 48" if both sides are accessible. When a round hole is what you require, core drilling is the method of choice. We core drill from 1/2" to 36" diameter holes to virtually any depth. Typical applications include HVAC openings, plumbing lines, floor drains, anchor holes and electrical and fiber optic runs.
