What are butyl joint sealants?
Butyl joint sealants are designed to create seals in concrete joints. They are commonly used in precast and underground structures where a reliable seal is required to prevent water infiltration.
Common applications
- Precast concrete structure joints
- Manholes and utility vaults
- Concrete box culverts
- Septic tanks and containment systems
- Reinforced concrete pipe (RCP) joints
Quick Decision Guide
- Concrete joint sealing → Crete-Stik
- Water infiltration risk → Hydrophilic Waterstop
- Surface sealing → Butyl Tape
- Fuel exposure → EX 221
When Butyl Joint Sealant Works Best
You should use butyl joint sealants when:
- Sealing between concrete-to-concrete joints
- Working with precast or underground structures
- Quality watertight performance is needed
When Not to Use Butyl Joint Sealant
You should not use butyl joint sealants when:
Active water infiltration or cold joints → Use Hydrophilic Waterstop
Fuel or hydrocarbon exposure → Use EX 221
Surface-to-surface sealing → Use Butyl Tape
External wrap or reinforcement needed → Use Strap Wrap
