Settled concrete slabs look unappealing and can be a major cause of trip & fall accidents. Traditionally, settled concrete was leveled and raised using a technique known as mudjacking. Mudjacking involves the use of slurry, which is poured underneath the concrete slab to raise the level as required. Today, there’s a better alternative known as Polyurethane foam concrete lifting. Read on to find some of the interesting aspects of the technique.
How does polyurethane foam concrete lifting work?
Polyurethane foam concrete lifting is frequently used for commercial and residential projects alike, mainly because it’s more effective than mudjacking. The process is similar in many ways. First a hole is drilled in the concrete, through which the polyurethane foam is injected underneath the surface of the concrete slab. The foam expands, causing the slab to rise. There are options in waterproof polyurethane foam too, which can prevent moisture damage, so you can expect the results to last for years.
One of the prime benefits of this technique is the lightness of the polyurethane foam. There is no additional pressure or stress on the ground below, and therefore, the concerns related to soil shifting are minimized. With polyurethane foam concrete lifting, there is no downtime either. Homeowners can use the concerned concrete area soon after. As compared to mudjacking, the size of holes drilled for injecting the polyurethane foam are much smaller, and you don’t need a lot of holes to get the job done.
Things to note
The first thing you need to know is the cost of polyurethane foam concrete lifting, which can be much higher than mudjacking. The polyurethane foam might be light in weight, but even a small amount of the material can cost huge. Secondly, you need a reliable and experienced contractor for the project. Make sure to do your homework. Find a company that’s licensed and insured and offers at least a year of warranty on the work. It is also wise to check the expertise of the concerned company, and if you have any doubts, you can ask for references too. Also, only a few contractors deal in waterproof polyurethane foam, so check your options before taking a call.
If you need assistance with polyurethane foam concrete lifting¸ always ask the concerned company to offer a free inspection and estimate. Check the terms and conditions of their services, especially with regards to the warranty.
