Block the Carrier. Stop the Attack
Bridges crumbling. Sewerage systems failing. Marine structures cracking and scaling. The common enemy? Sulfate attack—and it's hiding in plain sight.
The Sulfate Threat
Sulfates (SO₄) are everywhere: seawater, groundwater, sewage, fertilizers, and industrial environments. When sulfate-containing water contacts concrete, it triggers massive gypsum and ettringite formation—causing cracking, scaling, and "mushy" concrete.
At-risk structures: Bridges, sewerage infrastructure, marine structures, water treatment facilities, and agricultural buildings.
The Real Problem: Water is the Carrier
Concrete acts like a sponge. Bleedwater veins create pathways. Moisture carries sulfate ions deep into the structure where they form expansive gypsum.
Traditional solution: Surface coatings.
The flaw: Coatings wear away and do nothing to control moisture already trapped inside. Deterioration continues below the "sealed" surface.
Block the Carrier, Stop the Attack
Colloidal nano silica hydrogel technology seals concrete internally to eliminate the carrier mechanism.
Nano-particles (5-25 nanometers) penetrate 150mm deep—regardless of gravity—forming a permanent hydrogel that:
- Seals concrete porosity at the nano level
- Immobilizes internal moisture into gel state
- Blocks external moisture permanently
- Stops sulfate ion transport
- Becomes part of the concrete itself
UNSW study confirmed the hydrogel stops sulfate ion reactions.
Two Solutions
AQURON 300 Admixture – Added at batching for new construction protection from day one
AQURON 7000 Spray – Penetrates existing concrete 150mm deep, regardless of age
Proven Results
- Napier Port Wharves (NZ) – 15+ years of proven marine protection since 2009
- Bridge Decks (Regional NSW) – Arrested deterioration on multiple structures
- Water Treatment Plants (NZ) – Durability in highly contaminating environments
- Fertilizer Sheds & Waste Water Infrastructure – Protection across Australasia
The Bottom Line
Surface coatings attempt to keep water out. Colloidal nano silica hydrogel eliminates water's ability to transport sulfate ions—transforming concrete into waterproof, sulfate-resistant material.
