Deep-Penetrating Waterproofing That Lasts for the Life of Your Structure
What Is Crystalline Waterproofing?
Crystalline waterproofing is a chemical treatment applied to concrete surfaces or mixed into concrete during batching. When moisture enters, the active ingredients react to form insoluble crystals deep within the pores and capillaries of the concrete, permanently blocking water pathways.
This method offers internal, self-healing waterproofing that works even under hydrostatic pressure.
️ How Crystalline Waterproofing Works
- Applied to new or existing concrete
- Moisture triggers a chemical reaction
- Crystals grow within cracks and pores
- These crystals block water, even under pressure
- Reactivates in the presence of future moisture
Benefits of Crystalline Waterproofing
- ✅ Permanent waterproofing from within the concrete
- ✅ Self-healing of hairline cracks (up to 0.4 mm)
- ✅ Withstands positive and negative water pressure
- ✅ Non-toxic and VOC-free (safe for potable water tanks)
- ✅ Effective for both new construction and restoration
- ✅ Can be applied to horizontal and vertical surfaces
📍 Ideal Applications
