Terrazzo floors have always represented craftsmanship and durability — a surface built to last for generations. From the corridors of historic courthouses to the lobbies of modern office towers, terrazzo floors tell stories through their gleaming surfaces and timeless appeal. Yet, even the strongest terrazzo can show signs of fatigue over the years. Cracks, hollow spots, and worn finishes can turn once-gleaming surfaces dull and unstable.
For property owners, replacing these floors can be both expensive and unnecessary. That’s where Hollow Plane Injection comes in — an innovative method that strengthens and stabilises terrazzo floors from the inside out. Thanks to companies like TerCon System, which specialise in restoring terrazzo floors, this advanced technique has become a go-to solution for renewing terrazzo without the high costs of replacement.
Why Terrazzo Floors Lose Their Strength Over Time
Terrazzo may be built to last, but like any material, it can be affected by time, temperature changes, and movement in the structure beneath it. As buildings settle, voids can form between the terrazzo layer and the concrete base below. These air gaps, known as “hollow planes,” weaken the bond that holds the terrazzo in place. Over time, they cause flexing, cracking, and instability — a sure sign your terrazzo needs attention.
When left untreated, these hollow areas grow larger and eventually lead to visible cracks or breaks. That’s where Hollow Plane Injection becomes essential — it repairs the problem below the surface before it becomes visible damage.
How Hollow Plane Injection Restores Terrazzo Floors
Hollow Plane Injection is a highly specialised process used in the restoration of terrazzo floors. It works by filling those hidden air pockets beneath the terrazzo layer with a strong bonding resin or epoxy. Once the resin hardens, it reattaches the terrazzo to its base, restoring the floor’s structural integrity.
Here’s how TerCon System Services performs it:
- Inspection and Mapping – Experts identify weak or hollow sections using advanced acoustic testing, pinpointing every area that needs repair.
- Drilling Access Points – Small, precise holes are drilled through the terrazzo in the affected areas to create entry points for the injection.
- Injecting the Resin – A high-strength bonding material is injected into the hollow voids beneath the surface, filling every gap and locking the terrazzo back into place.
- Sealing and Polishing – Once the resin cures, the drilled holes are repaired using colour-matched terrazzo. The floor is then polished until it’s seamless and glossy again.
The result? A solid, even surface that looks and feels brand new — without removing or replacing a single section of the original terrazzo.
Cost-Effective and Sustainable Restoration
One of the greatest advantages of Hollow Plane Injection is its affordability. Replacing terrazzo can cost anywhere from $20 to $50 per square foot and often requires closing down an area for weeks. In contrast, terrazzo repair through injection typically costs a fraction of that — and it’s far less disruptive.
The terrazzo floor restoration cost associated with Hollow Plane Injection is lower because it preserves the original material. There’s no need for demolition, disposal, or installation of new flooring. This makes the process not only cost-effective but also environmentally responsible. Restoring instead of replacing means less waste, lower emissions, and a smaller carbon footprint — values that align perfectly with modern sustainable building practices.
Beyond Stability: Bringing Back the Shine
Once structural repairs are complete, the floor still needs to regain its signature sheen. That’s where TerCon System’s terrazzo floor experts take the process further with Terrazzo Grinding and Polishing.
After reinforcing the floor using Hollow Plane Injection, technicians grind the surface using industrial-grade diamond abrasives. This step removes minor surface flaws, scratches, and uneven spots. Next comes Polishing Terrazzo Floors Services, a multi-step process that uses increasingly fine abrasives to create a smooth, reflective finish.
By combining Hollow Plane Injection with grinding and polishing, the TerCon System ensures both structural durability and aesthetic brilliance — a terrazzo floor that’s strong beneath the surface and stunning above it.
Addressing Common Terrazzo Issues Along the Way
No terrazzo restoration project is complete without addressing the common issues that often accompany hollow planes. TerCon System integrates several complementary solutions to ensure each project is truly comprehensive:
- Terrazzo Crack Repair – Cracks are repaired with colour-matched epoxy, preventing moisture and debris from weakening the structure.
- Terrazzo Divider Strip Repair Services – Divider strips, which allow terrazzo to expand and contract naturally, are realigned or replaced when needed.
- Terrazzo Floor Grinding Services – Removes old sealers, stains, and surface imperfections to prepare for polishing.
These steps ensure the floor’s longevity, preventing further issues while restoring both strength and shine.
The TerCon System Advantage
What sets TerCon System apart is not just its technical expertise but its precision and attention to detail. The company’s TerCon System Services are designed to meet the needs of both commercial and residential clients who demand quality and durability.

A Sustainable Solution for the Future
In today’s environmentally conscious world, terrazzo floor restoration aligns perfectly with sustainability goals. Terrazzo itself is a composite of natural and recycled materials — often marble, quartz, or glass — making it one of the most sustainable flooring options available.
By choosing to restore instead of replace, property owners extend the life of their existing floors and minimise waste. Hollow Plane Injection, combined with terrazzo grinding and polishing, makes it possible to preserve the integrity of terrazzo for decades without compromising on appearance or strength.
It’s a solution that not only respects the craftsmanship of the past but also embraces modern sustainability standards for the future.
The Science Behind the Process
The materials used in Hollow Plane Injection are just as important as the technique itself. The resin compounds developed for this process are formulated to be flexible yet strong. They expand and contract with temperature changes, ensuring the terrazzo remains stable across seasons and under varying loads.
Once injected, the resin bonds chemically with both the terrazzo and the substrate beneath, creating a unified structure that eliminates movement and vibration. The surface, once reconnected to its foundation, becomes firm and resilient again — ideal for high-traffic areas in schools, hospitals, and commercial facilities.
Why Restoration Beats Replacement
Many property owners are often surprised to learn that restoring terrazzo floors can produce results that rival a complete replacement — at a much lower cost. The combination of Hollow Plane Injection, Terrazzo Crack Repair, and Polishing Terrazzo Floors Services restores both appearance and functionality without removing the original material.
Moreover, restored terrazzo floors maintain their historical and architectural integrity — a key consideration for heritage buildings and older commercial properties. Restoration also reduces downtime, making it ideal for facilities that can’t afford lengthy closures.
Conclusion: A Modern Approach to a Classic Surface
The art of terrazzo floor restoration has evolved significantly, and Hollow Plane Injection represents one of its most important advancements. By addressing the root cause of structural weakness and pairing it with expert finishing through Terrazzo Grinding and Polishing, TerCon System delivers a complete transformation — one that strengthens, beautifies, and preserves terrazzo floors for years to come.
