The “Hollow Tile” Problem in Nocatee
Why Builder-Grade Installations Are Failing in Coastal Oaks & Twenty Mile
How to Identify Spot Bonding Failures — and Fix the Slab Correctly
Many Nocatee homeowners are noticing a disturbing trend: tiles that sound hollow when walked on. As the premier provider of flooring removal in St. Johns County, we see these failures specifically in homes built between 2015 and 2020 — during Nocatee’s rapid construction boom when speed often took priority over installation quality.
The good news: it’s fixable. But it requires the right approach — not a patch job that will fail again within months.
What Nocatee Homeowners Are Experiencing
“Walk through your living room. If you hear a dull, hollow sound with each step — or feel tiles flex slightly underfoot — your installation has likely failed at the slab bond. This is not cosmetic. Left untreated, delaminated tiles crack, lift edges become trip hazards, and moisture infiltrates the gaps accelerating further damage.”
The Cause: “Spot Bonding” in Builder-Grade Installations
In the rush to build thousands of Nocatee homes simultaneously, some tile installers used “spot bonding” — applying blobs of thinset mortar at the corners and center of each tile instead of full back-buttered coverage. Industry standards require a minimum of 95% mortar coverage for floor tile. Spot bonding often achieves 40–60% — leaving large voids beneath each tile.
In Florida’s humid climate, ground moisture enters these voids, the mortar bond weakens, and tiles begin to delaminate from the slab — producing the hollow sound Nocatee homeowners are now hearing throughout their homes.
The Fix: Surgical Slab Removal — Not a Patch Job
You cannot simply re-grout or patch hollow tiles. The failed thinset must be completely ground off to expose bare, clean concrete before any new installation can bond correctly. A patch job over failed mortar will fail again — usually faster than the first time.

National 5700 Ride-On Scrapers
We use industrial National 5700 scrapers to remove the failed tile and thinset without damaging your Nocatee slab’s structural integrity. The blade angle is set precisely to pop material off the concrete — not gouge into it.
-
Diamond Grinding — Full Thinset Removal
After tile removal, residual thinset ridges are diamond-ground down to a flat CSP Profile 2 finish. This is the only substrate condition that allows large-format porcelain or premium tile to bond correctly and stay bonded.

Dust-Free Grinding — HVAC Protected
Thinset and concrete grinding generates heavy silica dust. Our HEPA dust-contained protocol captures dust at the source — protecting your Nocatee home’s HVAC system, air quality, and furnishings throughout the entire process.
-
Crack Isolation Membrane Prep
Once the slab is clean and flat, we prepare the surface for crack isolation membrane installation — an essential step for large-format tile in Florida’s concrete slab construction that prevents future tile failures from natural slab movement.

Ready for Large-Format Porcelain
The finished slab is clean, flat, and fully prepped for your new large-format porcelain or premium tile installation — with full mortar coverage required and documented so the same spot bonding failure never happens again.
