How to Polyjacking a Sinking Concrete Driveway
Do you have a sinking concrete driveway? Is it causing an eyesore around your property? Polyjacking can be a great solution for the unsightly problem. In this blog post, we’ll tell you what polyjacking is, why it’s beneficial, and how to do it yourself.
What is Polyjacking?
Polyjacking is a process of raising sunken concrete slabs by injecting a foam-like material beneath them. The foam is injected through small holes drilled into the concrete slab and then expands, pushing the slab up until it reaches its original level. This method of concrete lifting and leveling has been used since the 1970s and is often preferred over traditional methods like mud jacking because it can be done quickly with minimal disruption to your property.
Why Use Polyjacking?
Polyjacking offers several advantages over other methods of repairing sinking concrete driveways. It’s clean, fast, and doesn’t require any digging or heavy machinery. In addition, polyjacking provides superior support for the lifted slab compared to other methods because the foam material fills in all crevices and gaps beneath the surface. The foam also helps keep moisture away from the slab so that there isn’t any further deterioration over time. Finally, polyjacking requires no curing time so that you can immediately drive on your newly leveled driveway after it’s complete!
How to Polyjack Your Sinking Concrete Driveway
If you are looking to take on this project yourself there are a few steps you should follow: First, use a jackhammer or chisel to break up any large cracks or crevices in your driveway before beginning work—this will help ensure that the expanding foam adheres properly to the underside of your slab once injected. Next, drill several small holes (about ¾ inch in diameter) into your sunken slab at regular intervals—this will allow for easy access for injecting the polyurethane foam underneath it. After drilling all holes insert tubing into each one so that they extend down into the ground beneath your driveway—these tubes will act as pathways for injection of the expanding material below surface level. Finally, connect an injection gun to one end of each tube and then inject polyurethane foam until each hole is filled—as soon as you see new material oozing out from between cracks in your slab you know that you’ve reached an adequate level of filling beneath surface level! Allow 24 hours for full curing before driving on new driveway surface again!
Conclusion:
Polyjacking is an efficient way to lift sunken concrete driveways without having to dig up or replace them entirely – saving time and money in comparison with alternative solutions. If tackling this project yourself seems overwhelming at first glance – don’t worry! With some research and preparation – anyone can learn how to polyjack their own sinking concrete driveway with relative ease! As long as safety measures are taken seriously during preparation and execution stages – polyjacking should provide years of durable performance after successful completion! Good luck!
