Polyurethane foam injection is used for a wide variety of concrete repair and stabilization projects, such as leveling and raising concrete slabs, raising footings, and displacing underground water.
A two-part polyurethane is injected under the concrete slab or foundation that needs to be leveled. Underground, the parts combine to form an expanding foam that not only fills any voids under the slab but simultaneously compresses and strengthens the underlying soil while also lifting the slab or foundation back to its original height.
Polyurethane foam injection, also known as “poly-jacking,” is an alternative method to concrete repair related to mud jacking. However, polyurethane foam has many advantages over traditional mud jacking methods that allow it to be more effective and used in a variety of additional ways.
Because the foam is designed to work in conjunction with the existing soil rather than simply drilling through it, polyurethane foam lifting can solve a wider variety of problems than traditional slab or foundation lifting methods.
One of the biggest causes of foundation or slab settlement is unstable soil below them. Polyjacking helps fix this problem.
As the foam expands, it fills voids within the soil and pushes the soil particles together, compacting them from within.
A building’s footing is the part of its foundation in direct contact with the soil. When they start to settle, it can significantly affect the building itself.
Thankfully, the upward force of the expanding foam can precisely raise a building’s footings, returning them to the level at which they were built.
When soil is loose and uncompacted, it is much easier for water to penetrate it, settling into voids and inevitably serving only to loosen the soil more.
The polyurethane foam, however, fills those voids and compacts the soil, making it more difficult for water to weaken the soil underneath the slab.
When comparing polyurethane injection to alternative methods, polyurethane injection is quicker, more precise, and more structurally stable. In fact, applying polyurethane gets the job done with less disturbance. In addition, polyurethane is also moisture and decay-resistant, so you can count on it to last longer than alternative methods.
