Expansion joints are essential for protecting commercial buildings from water intrusion—especially in New England’s harsh climate. These joints allow materials like brick and concrete to expand and contract without cracking.
When they fail, they become one of the most common entry points for water.
How They Prevent Water Damage
Properly sealed expansion joints:
- Absorb movement from temperature changes
- Prevent cracks in masonry and concrete
- Block wind-driven rain and moisture
- Protect interiors from leaks and mold
In regions like Massachusetts and across New England, freeze-thaw cycles make joint performance even more critical.
Code Requirements to Know
Commercial properties must meet:
- Massachusetts State Building Code (780 CMR) – requires protection against water intrusion
- International Building Code (IBC) – mandates movement accommodation
- ASTM C920 – sets sealant performance standards
Non-compliance can lead to costly damage and liability.
Signs of Joint Failure
Watch for:
- Cracked or missing sealant
- Gaps or separation
- Interior water stains
- Mold or mildew
