Construction professionals use both hand and power tools to create grooves through concrete surfaces. Concrete grooving tools include tools that create grooves through wet, freshly poured concrete and machines that score grooves through tough, cured concrete. Whether you're creating expansion joints or decorative carvings, learn about concrete grooving tools, and select the right one for your project.
Like a mason's trowel, the hand groover is essentially a metal plate attached to a handle. The hand groover creates grooves, control joints and expansion joints through partially cured concrete. A thin, metal divider protrudes from the center of this tool's flat base plate. To create a groove with this tool, a concrete worker presses the base plate and protruding divider into partially cured concrete and runs the tool across the concrete's surface. The hand groover's U- or L-shaped handle protrudes from the top of the metal base plate and is made of wood, plastic or metal.
The pole groover places a traditional hand groover at the end of a long, broom-like extension pole. The length of a pole groover ranges from 3 feet to over 10 feet. The extended reach of a pole groover allows the concrete worker to create grooves across large slabs and in inaccessible areas.
Concrete workers frequently use this multipurpose, handheld power tool to cut cured concrete. The angle grinder's motor rapidly spins an abrasive blade to slice through concrete surfaces. A concrete worker presses the edge of the tool's circular blade against and into the surface of dried concrete to create decorative grooves, control joints and expansion joints.
Conceptually similar to the angle grinder, the concrete saw's powerful motor spins a large abrasive blade to slice and create grooves through concrete. In general, there are two types of concrete saws: the wet saw and the dry saw. The concrete wet saw uses a built-in pump to distribute water over both the cutting surface and blade. The water lubricates the blade to extend its life and reduces the amount of dust produced during cutting. Many wet saws are large, walk-behind machines. Like the wet saw, the dry saw spins an abrasive blade to slice through cured concrete surfaces. The dry saw is usually portable but substantially larger than an angle grinder and requires two hands for operation.
