Cost to Install a Concrete Sidewalk

After dumping the concrete into the forms, level the concrete as you pour every few feet with a screed board (a straight 2x4 about 1 ft. longer than the width of the sidewalk). Rest the screed board on the forms and use a sawing motion while pulling the board toward the end of the pour. Mar 25, †∑ For a long-lasting sidewalk, plan on a base of gravel under 4 inch of concrete. If you live in a frost-free climate with a natural sand base with good drainage, you can pour right on top of the sand. But other soil types will expand and contract with weather conditions and can crack overlying concrete.

Play it safe, call For a longer sidewalk, place plur joints across the form work every 6 to 8 feet to give the sidewalk a natural "break point", otherwise nasty irregular looking cracks will appear in the sidewalk later.

Expansion joints can be simply an indentation cut into the wet concrete as it is curing, to control where a how to pour a sidewalk with concrete may appear later. Or it can be an actual break in the sidewalk with either a heavy concrete felt, or a thin strip of decorative pressure-treated lumber that can be sealed or painted. Make sure your reinforced metal mesh does not span over an expansion joint, or you will sidewalm get a nice clean line where a break may occur.

Mar 13, †∑ Push the tools through the concrete while keeping the outside edges of the tools level with the concrete. Concrete likes to crack in squares. Be sure to put score marks or dummy joints in your sidewalk. These should be spaced apart equal to the length. e.g. 4' wide = Dummy Joints should be spaced every 4"/ 5'=5". Concrete sidewalk: excavate, prepare, pour, and broom finish linear feet of 48" wide by 3" thick slab with rebar, wire mesh, and aggregate/sand base. $ per foot. Working from the walkwayís lowest point to its highest, begin pouring concrete into the form. Roughly level the concrete with the back of a garden rake as soon as you finish pouring. Before the concrete gets too hard, smooth and level the concrete by sliding a 2Ē x 4Ē board back and forth across the tops of the forms (Image 1).

By Glenda Taylor. Though made from one of the most durable construction materials around, even once-strong concrete sidewalks can deteriorate over time from repeated freeze-thaw cycles, ground movement, or excessive weight. In most communities, there are two sidewalk classifications. If the sidewalk is a shared-use sidewalk, you may be required to replace at least the section that contains the large crack or cracks , but you may wish to replace the section even if the crack is on a personal sidewalk.

If the subbase is not structurally sound, wide cracks can be difficult to repair and only a temporary solution. Such cracks should be filled with a flexible sealant to prevent water from running through and saturating the soil below, leading to future soil-movement problems. Fortunately, that process is a cinch with a good flexible sealant like Polyurethane Concrete Crack Sealant. For the best results, check out this Quikrete video to learn how to prep cracks before filling them and how best to apply the flexible sealant.

When dry, the sealant has a texture and color similar to natural concrete. That said, a half-inch or more of crumbling along the interior joints or edges of the sidewalk could indicate weak concrete, in which case you may benefit more from replacing rather than repairing the sidewalk.

One or two small crumbled areas along the edges, however, possibly caused by heavy vehicles rolling over the sidewalk, could be prime candidates for repair.

Simply mix, trowel, and smooth Vinyl Patcher over the damaged areas to create a new level surface and clean edges. See it in actionóand get pro tips on the correct way to use itó in this video. No two ways about it: Concrete is going to crack. Contractors and savvy do-it-yourselfers guide where the cracks will appear by cutting control joints into freshly poured sidewalks at spots where the concrete is most likely to split. These control joints serve as weak points in the concrete, which will then be more likely to crack along them rather than in the center of a slab, where cracks would detract from the look of the entire sidewalk.

Most of the time, control joints work exactly as planned, and natural cracking along these predetermined seams goes unnoticed. On the other hand, extensive hairline cracks that run like spiderwebs throughout large areas of a sidewalk could be signs that there was something wrong with the original concrete mix.

If this is the case, you should consider replacing all, or most, of the sidewalk. At the very least, monitor the cracks, and take steps to replace the walkway if they get bigger. The polymers in this masonry product form a strong bond with the existing sidewalk, so your fix, though quick, will be long-lasting.

As in all household projects, good prep work is essential for good results, so check out this Quikrete video on how to apply Concrete Resurfacer. While concrete of almost any age can remain strong and resist cracking and crumbling, older sidewalks have been subjected to the elements far longer, and all that exposure takes a toll on concrete. The older the walkway, the more likely it is that individual sections will have heaved and shifted in the wake of extreme temperature fluctuations and ground movement.

In older neighborhoods, and particularly in residential historic districts, uneven concrete slabs can create tripping hazards, making sidewalks dangerous for pedestrians. In some communities, you may be able to hire a slab-jacking contractor to level the sections, but if the sidewalk is very old more than 50 years , you might find that investing in replacement makes more sense than continual repairs.
