Polyurethane foam injection is used for various 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, which needs to be leveled. Underground, the parts combine to form an expanding foam that fills any voids under the slab, compresses and strengthens the underlying soil, and lifts the slab or foundation back to its original height.
Polyurethane foam injection, also known as “poly-jacking,” is an alternative concrete repair method to mud jacking. However, polyurethane foam has many advantages over traditional mud jacking methods, making it more effective and allowing it to be used in various other ways.
Because the foam is designed to be worn with the existing soil rather than drilled 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 the foundation or slab. 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 it starts 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, settling into voids and inevitably serving only to loosen the soil further.
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. Applying polyurethane gets the job done with less disturbance. Additionally, polyurethane is also moisture- and decay-resistant, so you can count on it to last longer than alternative methods.
