Crystalline vs Membrane Waterproofing — Which is Better for Indian Roofs and Basements?
Crystalline waterproofing works by forming crystals within concrete — integral and permanent. Membrane waterproofing is an external barrier that can degrade, peel, or puncture over time.
Option A
Crystalline Waterproofing
₹80-150 ₹ per sq ft
VS
Option B
Membrane Waterproofing (Bitumen/TPO)
₹60-200 ₹ per sq ft
🏆
Winner: Crystalline Waterproofing
Crystalline waterproofing is the superior long-term solution for structural waterproofing of basements and foundations. Membrane systems work well for roofs and non-structural applications.
