Even concrete slabs can hamper the curb appeal of your property, besides causing tripping hazards. There are two major options when it comes to concrete leveling, also known as concrete raising – mudjacking and polyurethane foam concrete lifting. In this post, we will talk about the latter in detail.
What’s polyurethane foam concrete lifting?
Polyurethane foam concrete lifting is a newer method of leveling uneven concrete slabs. For the purpose, a small hole is drilled on the surface of the concrete. Through the hole, polyurethane foam material is injected underneath the slab. The foam expands and causes the concrete slab to rise. In recent years, polyurethane foam concrete lifting has been extensively used for commercial and residential projects alike.
The pros and cons
Traditional mudjacking involves using slurry for the same job, which exerts additional pressure on the surface underneath. That isn’t the case with polyurethane foam concrete lifting. With polyurethane foam, you don’t have to bother much about the amount of material used, since the foam expands effectively. Also, the material is light, so there are no additional concerns related to the ground underneath. The second benefit of polyurethane foam concrete raising is the lack of downtime. The concrete slabs can be used soon after the job is done, and therefore, polyurethane foam concrete lifting works better for commercial needs too.
On the flip side, this is more expensive than mudjacking. With polyurethane foam concrete lifting, you can expect to pay five times more than the traditional technique, but if you go by the results and pros, the investment is worth considering. Also, you can go for waterproof foam material, which has its own benefits, and if the damage caused by soil movement and moisture can be minimized, the results can last for years.
Finding a contractor
Not all contractors and foundation repair experts deal with polyurethane foam concrete lifting, so check online to find the best options. Ask them to offer an estimate in advance, and don’t forget to get a schedule for the job. If you have any specific questions, do seek answers, and don’t forget to read the reviews of the concerned service online.
Usually, polyurethane foam concrete lifting comes with a warranty of one year, but contractors may have different terms and conditions, which must be checked in detail. If you are working with a repair service for the first time, always ask for client references.
