EPDM vs PVC Seals in Expansion Joints: Which Is Better for India?

The seal inside an expansion joint is what keeps water out. Choosing the wrong seal material is one of the most common — and costly — mistakes in building construction.

PVC Seals

• Cheaper upfront
• Becomes brittle in 3–5 years under UV and heat
• Cracks in Indian summer temperatures (50°C+ surface temperatures)
• Requires replacement, causing disruption to building operations

EPDM Seals (DSeal Standard)

• Retains flexibility from -40°C to +120°C
• UV resistant — no degradation under direct sunlight
• Ozone and weathering resistant
• 20+ year service life in normal conditions
• Slightly higher upfront cost — much lower total cost of ownership

All DSeal expansion joint systems use premium EPDM seals as standard. We do not compromise on this — and neither should your specification.
