Use Case: Structural Patch & Repair
DOT-Spec Concrete Repair That Flexes Without Failure
Elephant Armor is a single-component, fiber-based, zero-polymer engineered ductal mortar. Its PVA fibers create a molecular bond within the matrix, providing extreme tensile and flexural strength that rigid mortars like SikaTop simply cannot match.

Head-to-Head Comparison
Elephant Armor vs. SikaTop (Rigid Repair Mortars)
| Property | Elephant Armor | SikaTop |
|---|---|---|
| Flexibility | Engineered ductility -- flexes without failure | Rigid, cracks under stress and thermal cycling |
| Shrinkage | -0.019% near-zero shrinkage [ASTM C928/C157] | Typical shrinkage causes micro-cracking at repair edges |
| Compressive Strength | 4,000 psi in 4 hours, 7,000 psi at 28 days | Standard cure schedules, slower return to service |
| Minimum Thickness | Structural at 1/4 inch thickness | Thicker minimum application required |
| Bond Mechanism | PVA fiber molecular bond + mechanical interlock | Polymer-modified surface bond only |
| Chloride Resistance | 321 Coulombs (Very Low) [ASTM C1202] | Higher permeability to chloride ions |
| Freeze-Thaw | Resists de-icing salts and freeze-thaw cycling | Standard resistance, vulnerable in harsh climates |
