What Kind of Foam is Used to Raise Concrete?by Scott M. Professional Writer
There are many different types of foam that one can use to raise concrete. Some foams are more dense and rigid, while others are more lightweight and flexible. In this article, we will discuss one of the best foams that can be used to raise concrete which is Polyurethane foam.
About Polyurethane foam
-Polyurethane foam is a type of plastic that is made from two main ingredients. They are polyol and isocyanate.
-Polyurethane foam can be either rigid or flexible, depending on how it is made.
-Rigid polyurethane foam is used in construction and insulation applications, while flexible polyurethane foam is used in upholstery and bedding.
-Polyurethane foam is an excellent material for raising concrete because it is strong and durable, yet lightweight and easy to work with.
How to use Polyurethane foam to raise concrete
Polyurethane foam can be injected into cracks in concrete to raise and level the surface.
The foam will expand and fill the crack, lifting the concrete and making it level again.
Polyurethane foam can also be used to fill voids beneath concrete slabs.
The foam will support the weight of the slab and prevent it from sinking or settling.
Benefits of using polyurethane foam to raise concrete
-Foam instead of concrete is a cleaner method
Lifting concrete using polyurethane foam requires less manpower. The contractor will only be required to drill about five to eight inches holes through. There won't be a huge mess to deal with like when traditional mud jacking is used.
-Foam concrete raising is less disruptive as compared to other methods
This is true especially when the slab being lifted is located in a highly visible or delicate area. With foam raising, only small holes need to be drilled. This means that there is very little damage to the surrounding area.
-Foam raising is versatile and can be used in a variety of applications
This method can be used to lift concrete slabs, sidewalks, driveways, pool decks, and patios. It can also be used to level out concrete steps and landings.
-Foam concrete raising is cost-effective
This method is often less expensive than other methods of concrete repair such as mud jacking or replacing the entire slab.
Polyurethane foam is an excellent material for raising concrete. It is strong and durable, yet lightweight and easy to work with. It can be injected into cracks in concrete to raise and level the surface or used to fill voids beneath concrete slabs. Polyurethane foam is also less disruptive and more cost-effective than other methods of foam concrete raising or repair.
