The hidden problem
Is This Happening Behind Your Seawall?
In South Florida and coastal regions, many seawall failures begin underground, long before visible cracks appear. Water moves through porous limestone, erodes backfill, creates underground voids, quietly removing the ground that holds everything in place.

Common warning signs
⚠ Sinkholes, soft spots, or settling behind the wall
⚠ Soil or sand washing out through cracks or joints
⚠ Water moving under or behind the seawall
⚠ Pavers, patios, or landscaping sinking toward the water
⚠ Repeated patching without solving the root cause
⚠ Concern that costly full seawall replacement may be coming
⚠ Leaning, separating, or settling wall sections

Understanding the underground problem makes the solution much clearer. Watch before reading the process below.
The Gap Traditional Repairs Leave
Traditional Repairs Treat the Wall.
Sealor Treats the Ground Behind It.
Surface patching, wall repairs or even full replacement may not solve the subsurface problem when water, voids, and porous coastal soils continue to move behind the structure.
"This is not just seawall repair. It is the beginning of a new category of underground climate infrastructure."
Alexander Suma, Inventor of Sealor & Co-founder, Nexuma

The process
Injected like a treatment.
Forms like limestone. Protects like advanced concrete.
Three steps from hidden failure zone to durable biogenic limestone barrier.
01
Diagnose the Failure Zone
Our field partners identify backfill washout, voids, porous zones, groundwater pathways, and soil loss behind or below the seawall through visual inspection and geophysical assessment.
02
Inject the Sealor Treatment
Our specialized partners drill a small hole behind the seawall till below the ocean floor. Our biogenic solution is injected under a low pressure. This is repeated along the length of the seawall with a few feet spacing to avoid any future erosion issues and extend the seawalls lifetime with decades.
03
Form a Biogenic Limestone Barrier
Sealor solidifies and bonds the injected backfill, underground and seawall panel within days. Monitoring equipment can be installed in the drilling hole for predictive maintenance.
The seawall is now structurally extended and strengthened from behind minimizing any future erosion risk and created a structural system with comparable properties of high strength concrete.

The Sealor breakthrough
We turn vulnerable ground into protective biogenic limestone
Sealor uses controlled biogenic mineralization to form natural limestone material inside porous and eroded ground. Instead of tearing out the wall or applying short-lived patches, Sealor is injected into the vulnerable subsurface zone.
It fills all pore spaces, binds loose material, and creates a durable, sustainable, high strength, impermeable mineral barrier where water once flowed freely.
"This is not just seawall repair. It is the beginning of a new category of underground climate infrastructure."

Sealor in the Spotlight:
A Royal Moment for Coastal Innovation
At the University of Miami, Rosenstiel School, Sealor's Founder & CEO Dr. Alexander Suma had the honor of presenting our novel technology to King Willem-Alexander of the Netherlands, Miami-Dade Mayor Daniella Levine Cava, Dutch Minister Sjoerdsma of Foreign Affairs, Dutch Ambassador Birgitta Tazelaar, and Drew Bartlett, Executive Director of the South Florida Water Management District.
It was a privilege to explain Sealor's initiation story, how fast we have developed our technology, and why this innovation matters so impactfully for flood-prone regions like South Florida.
