Polyurethane foam injections are a slabjacking procedure that uses a much lighter material compared to cement grout. This lighter material is faster and easier to install, and it offers a greater chance of long-term success. In addition, there is a much shorter cure time with residential polyurethane services compared to mudjacking, which takes up to 28 days to fully cure.
If that wasn’t enough to sell you on poly injections, this material also reaches 90 percent of its full compression strength after just 15 minutes. Therefore, you don’t have to worry about load bearing capacity, as it has the ability to hold tens of thousands per square foot immediately. Aside from the cure time and strength of the material, polyurethane foam injections leave little to no mess.
Here are five things to know about residential polyurethane injections and why they make a great foundation repair solution!
1. Quick Installation and Dry Times
Poly injections take about two to four hours to complete. The process is actually very simple. Small holes are drilled into the existing concrete, and then polyurethane is injected via ports. The material expands below the slab, lifting the concrete. The ports are removed and the holes are filled with concrete. The material sets in less than 30 seconds, and driveways and roadways can be driven on immediately after.
2. Safe for Humans and the Environment
Polyurethane injections do not contain any harsh chemicals that are often found in regular concrete repair methods. This makes them a safe option for the environment. Polyurethane is made from a resin and isocyanate that combine to make a solid form. In fact, these materials are so safe, they are even used in pacemakers that people wear inside their bodies!
3. Less Machinery and Disturbance
Mudjacking requires a lot of heavy machinery because the materials are heavier, and there’s more cleanup. This means that you’ll have to tolerate large equipment on your lawn, and potentially have to clean up or restore flower beds, bushes, grass, etc. Fortunately, polyurethane injections require small holes and a lightweight material, so there’s minimal disruption to your home.
4. Long-Lasting Solution
Residential polyurethane services have a long lifespan that can reach over five years or more depending on the soil conditions, maintenance and other factors. They are not a permanent solution, though. But, poly injections will not degrade in extreme temperatures, dry and wet freeze-thaw testing or fungal attacks. And, at the end of the material’s life, it can be recycled or reused.
5. Economical
Poly injections are a cost-effective way to repair your residential foundation. They can typically be done for half the cost of pouring new concrete. Not only is the material itself economical, but so is the installation process. With shorter installation times and less equipment, you get to save on these aspects as well.
