Seeing white, chalky staining on balcony tiles — or even running down the fascia of the building? That’s called efflorescence.
Efflorescence occurs when moisture travels through the substrate, carrying salts to the surface as it evaporates. The result is that powdery white residue you often see on tiles, grout, or staining down the building façade.
One of the most common preventable causes 👇
🚧 No balcony trim installed during waterproofing.
A correctly installed balcony trim directs water away from the edge, stops moisture tracking back underneath the tiles, and protects the waterproofing system long term. Without it, water can escape into surrounding areas — leading to staining, deterioration, and potential system failure over time.
Waterproofing isn’t just about what’s underneath — it’s the finishing details that make all the difference.
