Laboratory Tests Confirm AgriCrete’s Superior Water Resistance

Recent independent laboratory testing has validated what our customers have been experiencing in the field—AgriCrete’s two-product concrete preservation system delivers exceptional water resistance that far exceeds industry standards.

The Water Resistance Challenge

Water penetration remains one of the primary causes of concrete deterioration:

• Freeze-thaw damage occurs when water seeps into concrete and expands during freezing
• Rebar corrosion accelerates when moisture reaches steel reinforcement
• Efflorescence forms when water dissolves internal salts and brings them to the surface
• Biological growth thrives in damp concrete environments

Rigorous Testing Protocol

Our two-product system—combining PIM+ penetrating treatment with PTS+ topcoat—underwent a comprehensive water resistance assessment following modified ASTM standards:

1. Water Absorption Testing (modified ASTM C642)

   • Concrete samples treated with individual products and the complete system
   • Measurement of water uptake over 24, 48, and 72-hour periods
   • Comparative analysis against untreated control samples

2. Hydrostatic Pressure Resistance (modified ASTM D5385)

   • Exposure to water under pressure of 30, 60, and 90 psi
   • Testing for breakthrough and seepage
   • Evaluation of long-term resistance capabilities

3. Simulated Weather Exposure

   • Cyclic testing with water spray, UV exposure, and temperature fluctuations
   • 500 hours of accelerated weathering equivalent to approximately 5 years of exposure
   • Measurement of water resistance before and after weathering

Remarkable Results

The test results demonstrated clear superiority of the AgriCrete two-product system:

Test Parameter	Untreated Concrete	Single Product	Complete System
Water Absorption (72h)	5.8%	1.9%	0.3%
Pressure Resistance	15 psi	45 psi	>90 psi
Post-Weather Absorption	6.2%	2.3%	0.4%

Key Findings Explained

1. Dramatic Reduction in Water Absorption The complete AgriCrete system reduced water absorption by 94.8% compared to untreated concrete. Even after accelerated weathering, protection remained above 93%.

2. Synergistic Protection While each product provides significant protection individually, the two-product combination demonstrated synergistic effects, with protection levels far exceeding the sum of individual components.

3. Long-Term Durability After accelerated weathering equivalent to 5 years of exposure, the AgriCrete system maintained nearly identical water resistance properties, indicating exceptional longevity.

4. Superior Hydrostatic Pressure Resistance The complete system withstood the maximum test pressure of 90 psi without breakthrough—equivalent to a 207-foot water column or immersion at 90 feet depth.

Real-World Implications

These laboratory findings translate to significant practical benefits:

• Extended Concrete Lifespan: Dramatically reduced water penetration means slower deterioration and longer service life
• Lower Maintenance Costs: Water-related damage prevention translates to fewer repairs and interventions
• Improved Safety: Better structural integrity and reduced surface degradation
• Enhanced Sustainability: Longer-lasting concrete reduces replacement needs and carbon footprint

The Science Behind the Results

Our two-product system creates a multi-layer defense:

1. Deep Structural Transformation: PIM+ penetrates deeply to replace water-soluble compounds with crystalline structures that physically block water migration
2. Hydrophobic Surface Barrier: PTS+ creates a water-repellent outer layer that prevents water from making contact with the concrete surface

This combination of internal waterproofing and external water repellency ensures comprehensive protection against water infiltration from any direction.

Experience the Difference

Don’t let water damage compromise your concrete assets. The AgriCrete two-product system provides scientifically proven protection that preserves concrete integrity against one of its most persistent threats.
