Polyurethane Concrete Raising FAQ’s
We get so many questions about Polyurethane Concrete Raising. Here is your one stop shop to all your questions!
What is Polyurethane?
If you want to get into the science behind Polyurethane you can read about it here. But in Layman’s terms Poly is a substance or material consisting of very large molecules composed of many repeating subunits that are joined by urethane links, hence Polyurethane. Polyurethanes are used in the manufacture of high-resilience foam seating, rigid foam insulation panels, microcellular foam seals and gaskets amongst other things.
What is the process for having Polyurethane Concrete Raising done?
The process is actually quite simple! Small holes are drilled into the existing concrete where the Polyurethane is then injected via ports that have been placed into the drilled holes. The Polyurethane then expands below the concrete slab. As it expands the concrete raises! The ports are removed, and the holes easily filled with small amounts of concrete.
How long does the process take?
The expansion of the product takes only minutes and is fully cured within 30 minutes. So as far as an inconvenience, we would say next to none! The open ports are easily filled with small amounts of concrete to leave the slab full and intact!
How much does it cost?
There are always things to take into consideration when figuring cost for this type of project. The main consideration being what area needs to be raised and the square footage. Condition of the slab as well as how many inches the slab needs to be raised will also take part in determining the cost. Smaller projects can start anywhere from around $800 to $900 and can go up from there.
Why shouldn’t I just replace my concrete slab?
Most people do not like inconvenience so that is the first reason. Replacing the entire concrete slab requires breaking up all the concrete, hauling it away, prepping the foundation and then pouring new concrete. It takes 24 to 48 hours for the initial setting process where then people can walk on the surface. 7 days after partial curing vehicles can then drive on it and 28 days for the concrete to be fully cured. Also, there is price. There is a lot of manual labor involved with getting a whole new concrete slab put in. A lot of labor equates to a lot of money.
Is Polyurethane Concrete Raising the best option for concrete raising?
Yes!! There is a process called Mudjacking which has a similar process to Polyurethane Concrete Raising, you can read more about the differences here. Mudjacking requires a bigger hole to be drilled into the concrete. Unfortunately, Mudjacking does not offer a long-life solution whereas Polyurethane Concrete Raising brings a cleaner, more economical, and long-lasting solution.
Under what situations is Polyurethane Concrete Raising not suitable?
A few instances where Polyurethane Concrete Raising would not be a viable option for you. First, if the concrete slab is in such poor shape that it is cracked and broken apart. Polyurethane raises full slabs, if there are small cracks that is ok, but if it is so cracked that it is in pieces, there is no way to use this method and the best option would then be to replace your concrete. Second, if there is a structure (columns, deck, stairs) resting on top of the concrete then there is a good chance Polyurethane Concrete Raising process may not be feasible unless the structure is removed.
