The Most Apt Basement Waterproofing System. (Part-2)
In our preceding article, we discussed why HDPE membranes are the clear choice for Basement Waterproofing.
Nonetheless, it is crucial to acknowledge that waterproofing membranes have inherent limitations, such as;
• Susceptibility to puncture damage,
• Challenging repairs due to inaccessibility and difficulty in locating the affected area,
• & A lifespan that may not align with the desired longevity of the overall structure.
Consequently, we recognize the need to augment the protection offered by HDPE membranes with a reliable backup system.
In this article, we shall delve into the concept of an innovative technology known as Integral Crystalline Waterproofing (ICW), which has been revolutionizing concrete structures’ waterproofing and repair practices globally for the past three decades.
The Root Cause: Moisture in Concrete Structures
In many cases of concrete degradation, the primary cause can be traced back to the presence of moisture or water within the concrete. Water infiltrates through the concrete matrix’s pore system or micro-cracks, posing a threat to the structure’s durability. Effectively waterproofing the concrete is imperative to ensure its long-term integrity.
The Working Principle of Integral Crystalline Waterproofing
Integral Crystalline Waterproofing (ICW) operates on principles akin to concrete hydration processes. When ICW products are applied to concrete, they facilitate the formation of long, narrow crystals that occupy the concrete’s pores, capillaries, and hairline cracks. These crystals continue to grow throughout the concrete as long as water is present. Once the concrete dries, the crystalline chemicals remain dormant until they come into contact with water again, triggering the crystallization process once more.
Benefits of Integral Crystalline Waterproofing
1) Advanced Self-Sealing Properties: ICW-treated concrete exhibits remarkable self-sealing properties. When cracks appear due to drying shrinkage, settling, seismic activity, or other factors, water that enters through these cracks initiates the formation and growth of new crystals, effectively blocking and filling the gaps. This feature significantly reduces the long-term maintenance and repair costs of the concrete structure.
2) Reinforcing Steel Protection: Integral Crystalline Waterproofing prolongs the life of concrete structures by preventing corrosion of reinforcing steel, which can occur when salt, chlorides, or other waterborne contaminants infiltrate the concrete.
3) Sustainable Solution: The ICW technology is non-toxic, safe for use in potable water, and free from volatile organic compounds (VOCs).
4) Uniform Waterproofing: The ICW treatment ensures consistent waterproofing throughout the entire concrete volume.
5) Reduced Water Penetration: Integral Crystalline Waterproofing diminishes water penetration, even under pressure.
Endorsement and Reliability
The effectiveness of this system is further supported by the American Concrete Institute’s (ACI) 212.3R-10 Report on Chemical Admixture, which devotes a chapter to Permeability Reducing Admixtures that encompasses PRAH and PRAN classifications. The report affirms that Permeability Reducing Admixture – Hydrostatic Conditions (PRAH) products can adequately resist water penetration under hydrostatic pressure and are suitable for watertight construction.
Conclusion
Given that membrane failures can occur in various situations due to different factors, using concrete itself as a waterproofing barrier serves as a prudent backup solution. Integral Crystalline Waterproofing (ICW) technology offers a reliable and effective second line of defense for basement structures in the event of HDPE membrane system failure.
“Like water, resilience flows through the cracks, embracing challenges and transforming them into strength.”
