Polyjacking vs. Mudjacking
If you have concrete on your property that is sunken, uneven, or full of voids and spaces, you may be wondering what the best solution is. Sometimes, damaged concrete appears like it should be completely replaced, but several repair options can make your concrete as good as new. Polyjacking and mudjacking are both popular and effective methods for repairing your concrete, but which one should you choose? Here we will look at both solutions and help to steer you in the right direction.
Mudjacking is a process in which holes are drilled into the affected area of your concrete, and filled with a mixture of cement, water, and grout. This mixture, called slurry, will fill the voids beneath your concrete and, through hydraulic pressure, lift it back to its original level. Once this is complete, the holes can then be filled and the site is cleaned up. Mudjacking is a cost-effective process and can be applied to a variety of areas such as driveways, sidewalks, porch steps, and more. Although the slurry mixture gives strength to the concrete, it is also extremely heavy, adding weight to the sub-base. If the soil is already having trouble supporting the slab, it’s going to continue to compress when you add hundreds of pounds of slurry.
Like mudjacking, polyjacking also requires drilled holes and injections. This time, polyurethane foam is injected into the concrete, but through much smaller-sized and a fewer number of holes. This foam will expand an incredible amount and travel through the concrete, filling every void that is present. It can accurately lift your concrete even to 10/1000th of an inch! The polyurethane foam is much more lightweight than the slurry that is used in mudjacking, which may not provide as much tensile strength, but it allows for the soil around it to be compacted. This prevents future foundation failure and keeps the concrete stable for years to come. Unlike mudjacking, polyjacking is a quick process and the concrete can be used about 15 minutes after it is fixed. Polyjacking can also be applied to various places including your garage floor, walkways, patio, and more.
