Power of 
Concrete Lifting 
with Robbins 
Foundation 
Systems
Uneven concrete slabs are more than just an 
eyesore; they pose significant safety hazards 
and can devalue your property. Whether it's a 
cracked driveway, a sinking sidewalk, or an 
unlevel patio, these issues often stem from 
unstable soil, erosion, or poor drainage 
beneath the surface. Fortunately, there's a 
highly effective and cost-efficient solution: 
concrete lifting, also known as concrete 
leveling or slab jacking. Robbins Foundation 
Systems, a trusted name in foundation and 
concrete repair since 1952, offers expert 
concrete lifting services to restore your 
property's stability and appearance.
What is Concrete 
      ConcretLe liiftfintg iisn a sgpec?ialized process that 
involves injecting a material beneath a 
sunken or settled concrete slab to raise it 
back to its original, level position. This 
method addresses the root cause of the 
problem—voids and instability in the 
underlying soil—without the need for costly 
and disruptive concrete replacement. It's a 
precise, minimally invasive technique that 
can dramatically improve the safety, 
functionality, and curb appeal of your 
property.
The Robbins Foundation Systems 
Approach to Concrete Leveling
At Robbins Foundation Systems, we utilize 
advanced concrete slab leveling 
techniques, including polyurethane foam 
injection and pressure grouting. These 
methods are designed for precision, 
durability, and long-lasting results.
• Polyurethane Foam Injection: This modern 
technique involves drilling small holes (typically 
⅝-inch in diameter) into the affected concrete. A 
two-part liquid polyurethane foam is then 
injected beneath the slab. Upon injection, the 
foam expands rapidly, filling voids and exerting 
controlled pressure to lift the concrete. This 
method is highly efficient, lightweight, 
waterproof, and cures quickly, often allowing the 
surface to be used within an hour.
Pressure Grouting (Slab Jacking): A more 
traditional yet equally effective method, 
pressure grouting involves injecting a 
specialized slurry (often a mix of pulverized 
limestone, water, and sometimes Portland 
cement) beneath the slab through larger holes 
(around 1-inch in diameter). This material fills 
the voids and gradually raises the concrete. It 
creates a dense, stable base, making it ideal for 
various applications.
Why Choose Concrete Lifting 
Over Replacement?
• Cost-Effective: Lifting existing concrete is 
significantly less expensive than tearing out 
and pouring new slabs.
• Time-Saving: The process is much quicker, 
minimizing disruption to your daily life. Most 
jobs are completed in hours, not days.
• Minimally Invasive: Smaller drill holes mean 
less impact on your landscaping and 
surrounding areas.
• Enhanced Stability: By filling voids and 
compacting the soil, concrete lifting provides 
a stable, long-term solution that prevents 
future settling.
