Yes, you should always wet concrete before jackhammering to avoid harmful dust from becoming airborne. According to the U.S. Occupational Safety and Health Administration, they recommend a wet-cut method that involves continuous spraying of the concrete where the jackhammer bit hits. Use a jackhammer with a built-in sprayer attachment, or have a work partner spray the area with a garden hose and spray nozzle.

It is not advisable to pour concrete directly on dirt. Even compacted soil—known as a subgrade—is not strong enough to maintain the form of concrete. You can, however, pour concrete over concrete as long as the overlay has proper bonding agents and the slab below is clear of damage.

In most cases, yes, masons can build concrete forms and pour concrete for a variety of home improvement projects, including foundation pouring. Some masons may prefer to focus on more aesthetic and artistic masonry work, like building retaining walls, crafting custom fireplaces, tiling, or installing stucco siding, but most also have experience pouring concrete. You can always ask your masonry contractor if they also handle poured concrete projects.

Yes, fiber concrete can crack, and contrary to popular belief, it will crack under similar forces to rebar-reinforced concrete. The difference is in how the crack spreads through the slab. When you exert pressure on a slab, the slab flexes downward, putting tensile forces on the bottom of the slab. In rebar concrete, a crack at the bottom will also quickly appear on the top surface. In fiber concrete, the fibers hold the two sides of that bottom crack together, making it less likely for the crack to form on the top surface.
