Step Two: Estimate the Rebar Grid Clearance Try our reinforcing mesh calculator to estimate. The use of steel or fiber mesh can be used as an alternate form of reinforcement in some circumstances, and is often used for thinner slab pours. Most projects require rebar to be laid in a grid pattern with bars running in opposite directions and overlapping. For a patio it is common to use a #3 bar spaced every 18″-24″ while for a driveway #4 bar is often used with a 12″-18″ spacing.ĭifferent projects require a different size rebar and will require the rebar to be spaced differently. Rebar is often installed in a grid pattern, and to estimate the amount needed it will be important to first identify the size and spacing is appropriate for your project. Ĭalculating the amount of bar needed can be done in a few simple steps.
Using rebar as reinforcement adds considerable strength to concrete and reduces the overall slab thickness needed.
When installing a concrete slab or structure it is a good idea to add rebar, or reinforcing bar, to reinforce it and prevent it from cracking down the road.
