How To Repair Uneven Sidewalk

Cement sidewalks tin can provide a nice looking improver to a domicile. But they aren't just attractive; they too add together value to a property. Unfortunately, a characteristic of cement many people aren't aware of is that information technology's porous and information technology will absorb water. Over the seasons, water can get into the surface of a cement walkway and with melting and freezing cycles, the wet can actually cause cracks in the cement. Luckily, fixing cracks in a cement sidewalk isn't a difficult chore, well within the skill set of most homeowners, and the tools and supplies are readily available at your local dwelling shop.

Fixing Small/Hairline Cracks

A pocket-sized crack (anything less than 1/4") is actually straightforward to repair. You can make full the crack with premixed concrete crack filler that comes in tubes similar to caulking, or by mixing up a paste of Portland cement and water. No thing what you're going to employ to repair the crack, the first step is to clean out any dirt or other mess that's in the crack. Spray water into the crevice and apply a stiff broom to clear it out. If y'all're using a tube of crevice filler, follow the manufacturer's directions about how to use the product. In full general, you insert the tube into a caulking gun, cut off the tip of the container, and fill the crack up to inundation. So you scrape the surface smoothen and let it set every bit directed by the manufacturer. You may need to fill up the cleft a couple of times as the filler might settle.

If you're going to use your own mixture of Portland cement and water, it's a good idea to soak the cement around the crack with your hose so the cement is damp when you get to repair the fissure. This extra wet will stop the surrounding dry cement from literally pulling water out of the patching cement. Gear up your cement mixture so it has the consistency of a thick paste. Use a putty knife to strength it well downward into the crack and and so smooth the surface. Leave the repair alone for a couple of hours, and so spray information technology lightly with water and cover the patch with a plastic canvas. Once a day for the next two or 3 days, remove the plastic sheet and lightly spray the patch. Keeping information technology moist will let the cement repair to dry slowly (cure) and solid.

Fixing Larger Cracks

If your walkway has a larger fissure, you can repair it with a like process, but there are a couple of extra steps involved. Once again, start past cleaning out the crack using the potent broom and a hose, or fifty-fifty a force per unit area washer, to flush all the dirt out. Your side by side stride is to widen the base of operations of the existing crack to assist hold your concrete patch in place. Use a common cold chisel and a hammer to chip out concrete along the bottom edges of the crack—yous want to stop up with an inverted "5" shape with the sides of the crack widening out at the bottom. Clean out any physical fries or dust and thoroughly soak the crack with your hose (here once again, you want the concrete around the crack to be damp but don't go out any standing water in the cleft). It'south a good idea to employ a physical agglutinative to the walls of the crack so the new concrete volition bond solidly with the old.

Paint the adhesive along both sides and the lesser of the crack with an quondam paintbrush and allow information technology sit for a few minutes until the agglutinative becomes tacky. Apply your concrete patching mixture with a metal trowel and exist sure to pack it tightly into the expanded crack. Smooth the surface and allow the patch to dry for a couple of hours. After the patch has stale for a while, spray the area lightly with your hose and cover with a plastic sheet, removing information technology once a day to dampen the patch. Later on four days you lot can remove the plastic and expose the now cured physical to the elements.

Patching Holes in a Concrete Sidewalk

If the pigsty is pocket-size and shallow (less than 1/4") all y'all will demand to practice is clean it thoroughly and wet the edges, so add and level cement patching material. Exist sure to encompass the repair and proceed information technology moist while it cures only like your scissure repairs. If your sidewalk has a large deep hole (say one/2" or more) you should follow the undercutting process described to a higher place (widen out the bottom of the exposed concrete with your cold chisel so the patch volition actually get under some of the existing concrete). In add-on, you should as well fill the bottom of the hole with sand or gravel that you tamp down solidly to requite your patch a business firm base of operations. Wetting the sand before tamping it volition help to requite yous that solid base.

An alternative product that can exist used instead of filling with sand and topping with patching material is latex cement. It's made up of two components: Portland cement and a latex binder that yous mix together to course a quick-setting, durable cement. Latex cement is sand-based (no gravel) so it'south easy to trowel smoothen. In shallow holes (i/4") only use your metal trowel to pack the latex cement into the hole and level the surface. On deeper holes, apply the latex cement in layers of nearly ane/four to 1/2-inch and allow it to gear up before applying the adjacent layer. In one case again, continue the patch moist for a few days while it cures.

As y'all can see, repairing croaky or damaged sidewalks isn't a difficult task; the patch just requires a little maintenance or TLC for a few days. While it might be tempting to non keep the repair moist while the patch cures, don't try information technology. If the new cement doesn't get the chance to properly cure, information technology will apace interruption down and you'll be right back where you started, if not worse.
