A walk-behind flat saw uses a rotating diamond blade to cut concrete, asphalt, and other hard horizontal surfaces, often called "slab sawing". These powerful machines are used for precise straight cuts in applications such as creating control and expansion joints, cutting trenches for utilities, removing damaged sections of pavement or flooring, and for large-scale road and airport runway work. They come in various sizes and power sources (gas, diesel, electric) to suit different job scales and environments, from small repair jobs to major construction projects.

Concrete core drilling uses a specialized diamond-tipped bit to cut precise, cylindrical holes into concrete, creating openings for plumbing, electrical, and HVAC installations, as well as for extracting samples to analyze material properties. The process involves anchoring the drill to the surface, often with a vacuum base or bolts, and rotating the bit while applying pressure, frequently with a water feed to cool the bit and suppress dust. After drilling, a "core" or "slug" of concrete is removed, leaving a clean, perfectly round hole in the structure. 

Concrete hand sawing uses portable, gas-powered or electric handheld saws with diamond-tipped blades to make precise cuts in concrete, masonry, and stone for renovation, demolition, or repairs. It is ideal for tight spaces, small openings like doors and windows, and tasks requiring high accuracy where larger equipment can't be used. Wet-sawing with water is essential for cooling the blade and minimizing dust, though it creates a concrete slurry that needs cleanup 

Cutting an egress or safety window involves marking and then precisely cutting a new, larger opening in a concrete foundation using a masonry or concrete saw. The process includes steps such as placing temporary supports, drilling pilot holes at corners, cutting the concrete outline, knocking out the resulting block, and smoothing the opening. This work creates a larger opening for an egress window, which is required by building codes to ensure a safe exit from basements and other areas, and often requires installing a window well for drainage and escape 

A concrete wall saw is a track-mounted, diamond-tipped circular blade system used to make precise, controlled cuts in concrete and masonry structures. Powered by hydraulic or electric motors, the saw attaches to rails bolted onto the wall, allowing it to make precise vertical and horizontal cuts for applications like creating doorways, windows, and structural modifications while maintaining a smooth finish and preserving structural integrity
