3 Cement Raising Options To Repair Broken Concrete

Even though concrete is used more than another material made by man, it still has its flaws. Over time, it can sink and settle unevenly into the ground and look unsightly. If you have concrete slabs that need some attention, you may be looking at ways to get it repaired. Here are three cement raising options to repair your broken concrete and their advantages and disadvantages.

Concrete Replacement

If you have concrete that has severely cracked or deteriorated, you may want to replace it completely. A new pour of concrete will definitely look better, but may not match the color and texture of nearby concrete slabs. It also doesn’t address the reason behind why the concrete needed crack repair in the first place. If the weight of the slab caused the concrete to crack, it’s highly likely you’ll have the same problem again in the near future. This is also the most expensive of the three options.

Slab Jacking

Slab jacking or mud jacking is a cement raising technique that pumps grout through the concrete and lifts it up from underneath. The process drills holes into the concrete and then uses a slurry to fill concrete voids that were made. Once the filling voids in concrete steps are completed, further injection will lift the concrete up. Since it does add extra weight, the concrete will settle again over time if the soil underneath isn’t able to hold it.

Polyurethane Foam

This cement raising process employs a closed-cell polymer foam for lifting. This specific type of foam features gas pockets that are sealed from each other and prevents water from being soaked up. The foam is injected into a port that has been fastened to a hole drilled into the concrete. The port creates an expansion of air bubbles in the foam which do the actual concrete raising. The two parts of the foam mix in the nozzle after traveling down a set of hoses separately in liquid form.

The foam expands into the weak soil and increases its density within 15 seconds. It cures incredibly fast and you can drive your car onto the repaired slab in approximately 30 minutes. The foam won’t erode and won’t add weight to the concrete.

If you have damaged concrete, consider one of these cement raising options for your repair needs. Don’t wait for the problem to get even worse. Contact a concrete service professional today and get your concrete looking great again!
