Sometimes it can be more than a stumble and can cause serious injuries. When concrete sidewalks are built, they are perfectly finished and look smooth. But in course of time, the flaws and frailties rear their ugly head and they start cracking or become undulating. Life of a concrete sidewalk depends on the weather, soil and care put to it. Fluctuating temperatures take a toll on the longevity of the sidewalks. Sometimes the soil plays the devil when it shifts gradually due to accumulation of water causing the slab to sink. Abutting tree roots is also a cause to blame for. Human error at the time of construction cannot be left out since workers often don’t stick to the guidelines assigned to them.

Now repairing a concrete sidewalk can be can be an expensive deal. Some masonry companies charge $5 to $15 per square foot to demolish and remake a sidewalk. The cost of repairing a sidewalk depends on the size of repair, the amount of concrete to be used and the metal reinforcements. Now-a-days, with the advent of technology, a new technique called mudjacking has evolved which enables quick levelling of a sidewalk. Companies at Queens in NYC have been using this technique for quite some time now. Let’s have a look at the process of mudjacking.

How to fix a sidewalk slab?

Choosing the right repair condition

One has to keep in mind the weather condition and take a note of the temperature. A hot temperature will make the concrete turn stiff quickly before it can be poured into the sidewalk pump holes. Make sure that there is no unwanted water accumulating beneath the slabs.

Preparing the sidewalk slab for grout and concrete injection

Take a masonry drill and bore three holes in the slab. The diameter of the holes should be 1 inch and they should be 3 inches away from the edge of the slab to prevent cracking. The spacing of the holes should be minimum 6-8 inches apart. After that, drill into the sidewalk slab till you hit the soil.

Making the grout mixture

The grout formula should be mixed evenly with water in an aluminum container. Keep a close eye on the directions on the packaging and stir the solution with a masonry paddler at a medium speed.

Lifting the concrete slabs

Now take a grout pump-hose and put it in the center hole you made out of the three in the sidewalk slab. Fill the hole with the grout mixture. Shift the hose into the other holes and keep pouring the mixture till the slabs rise and reach the required level of the other slabs.

Filling the holes with concrete

Using a putty trowel, put concrete into the holes and fill it completely. Make sure the packing is firm. After that, level the top of the holes to ensure smoothness.

Check for any unevenness

The job is done. Now it’s time for an overview. Look out for any tilting or uneven levelling. Repeat this same process for the other sidewalk slabs to maintain evenness throughout the sidewalk.
