Concrete Lifting & Leveling Before & After Photos

Before photo shows a concrete slab that has settled into a void causing a tripping hazard and is very unappealing. After photo shows the concrete slab after it was injected with PolyLevel(R) to be raised and stabilized. The slab had its old sealant removed to our Nexus pro sealant installed. Sealant pro will protect the longevity of the concrete as well as keep our and liquids from going into the cracks. 

In Costa Mesa, California, Saber Foundations was contracted to fix an issue of sever concrete settlement.  The settlement was most likely caused by the combined weight of the concrete and what is supporting it.  The soil beneath the concrete compresses and can cause major problems.  Like the ones shown in this before photo,  the concrete had settled and the walls had begun to show the signs of the settlement by gapping.  Saber was able to quickly and affordably fix the issue for this homeowner, by using the PolyLEVEL™ process.  The PolyLEVEL™ process is a two part foam used to inject into the ground to form a fill that is strong yet light weight.  This process was completed and the end result was that of closing the gaps that the concrete sinking had caused.  The great thing about PolyLEVEL™ is it waterproof, it does not react with soil or water, and does not leak hazardous chemicals into the soil.  It also cures very quickly, so the process is messy and disruptive, in comparison to other foundation-lifting techniques.

Our PolyLevel Injection Process stabilized the wall that had cracked and sunk.

Kristin’s home in Long Beach, CA, had begun showing signs of distress. A once-stable backyard patio was now marked by widening cracks and uneven surfaces, becoming both a visual eyesore and a safety concern. What began as minor fissures eventually evolved into larger structural concerns, with portions of the concrete slab beginning to settle due to voids beneath the surface. The compromised patio not only impacted curb appeal but also created potential hazards for anyone walking across it—especially in an outdoor space meant for relaxation and gathering.

The Search for a Solution – When DIY Isn’t Enough

Kristin explored her options. Patchwork sealants and temporary fillers didn’t hold up against the ever-changing California climate. The cracks always seemed to return, and the settling worsened. It became clear that this wasn’t a surface-level issue—it was a problem beneath the slab, caused by voids and soil erosion that demanded professional intervention.

Why Saber Foundation Repair?

That’s when Kristin turned to Saber Foundation Repair, a trusted name in concrete and foundation solutions. Saber’s commitment to long-lasting, minimally invasive repairs immediately stood out. Through a seamless consultation process, Kristin learned how Saber’s team uses advanced methods like PolyLevel® Injection Foam and NexusPro® sealant to deliver results that last—without the mess or downtime of traditional methods like mudjacking.

The detailed inspection uncovered 211 square feet of void beneath the patio slab, contributing to the cracking and instability. Saber's specialists proposed a two-part solution: stabilize the slab using PolyLevel and seal the cracks and joints using NexusPro.

The Repair Process – Smart, Swift, Sustainable

On the morning of July 11, 2025, Saber’s expert crew arrived on time and ready. The process began with prepping and clearing the worksite to ensure proper material bonding.

Using PolyLevel, a lightweight, high-density polyurethane foam, the team injected the material beneath the slab through small, unobtrusive holes—each roughly the size of a penny. Within minutes, the foam expanded, filling the voids, and gently lifting the slab back to its proper level. Unlike traditional methods, PolyLevel doesn’t add weight to the soil, and it cures in just 15 minutes—meaning minimal disruption.

Next came NexusPro®, a durable silicone-based sealant. The team cleaned and routed the cracks, then applied the sealant to create a watertight, flexible barrier that resists UV rays, temperature changes, and future cracking. NexusPro’s fast curing time allowed Kristin to safely use the patio the very same day.

Transformation – From Tripping Hazard to Tranquil Haven

The difference was immediately visible—and lasting. What was once a cracked, uneven, and unsafe patio had been restored to a smooth, level, and beautifully finished outdoor space. The slab was now stable and protected from future soil erosion and water intrusion.

Kristin’s project included:

211 sq ft of void fill beneath the slab

30 linear feet of NexusPro® Crack Repair

28 linear feet of NexusPro® Joint Sealant

This wasn’t just a cosmetic upgrade—it was a structural reinforcement designed to last for decades.

The Power of Trust – Why Early Action Matters

Homeowners like Kristin often wait too long, hoping minor issues will fix themselves. But with foundation and concrete problems, early intervention is key. Saber’s transparent process, modern technology, and respect for homeowners’ time and property make it clear why so many Californians trust them for lasting results.

By addressing the issue head-on, Kristin avoided more costly damage, ensured her family’s safety, and preserved the value of her home.

A Win for Everyone – Curb Appeal, Safety, and Stability

In Long Beach’s fluctuating weather and soil conditions, Saber’s combination of PolyLevel and NexusPro proved to be the best concrete lifting and sealing solution available. Kristin’s patio is now secure, functional, and visually restored—an instant improvement in quality of life and home value.
