Crystalline Powder
Ober Crystalline Powder is a cement-based, brush-applied waterproofing solution for concrete. When mixed with water and applied, it penetrates the concrete, forming millions of needle-like crystals that block water pathways. These crystals develop deeper over time, depending on concrete thickness, environmental conditions, and moisture levels, achieving full waterproofing within 7 days to a month. Ober Crystalline Powder reacts with moisture to form insoluble crystalline complexes that seal capillaries and microcracks, even under high hydrostatic pressure. This active waterproofing technology remains effective throughout the life of the concrete, providing permanent water resistance
Features & Benefits:
- Stops water flow through concrete and protects the reinforcing steel from corrosion.
- Waterproofs small cracks and seals shrinkage cracks up to 0.4 mm wide.
- Its waterproofing performance improves with time and is permanently operational.
- Does not suffer from surface wear or abrasion.
- Can be applied to both the positive and negative sides of concrete.
- Treated concrete can sustain hydrostatic pressure up to 150m head.Simple to apply, just combine water on-site.
- Protects concrete against polluted water and corrosion.
- Suitable for damp substrates. And allows concrete to breathe, but not a vapour barrier.
- Deep crystallisation provides waterproofing for landscaping slabs, concrete rafts, and PCC.
