Joint Sealant
R&L Ohana installs expansion and control joint sealant systems, fire-rated and non-rated, at floor, wall and ceiling conditions. We self-perform section 07 92 00 on commercial construction throughout Hawaii.
What the Scope Covers
Expansion joints, control joints and construction joints. Fire-rated joint systems installed to the listed UL system where the assembly carries a rating, and non-rated sealant where it does not. Backer rod, primer, tooling and finish per the detail and the manufacturer’s instructions.
Why It Is On Our Truck
Joint sealant lives next to firestopping. Both are rated-assembly work, both are inspected, and both come down to installing a listed system exactly as it is listed rather than approximately. Running them under one subcontractor means the rated joints and the rated penetrations are documented by the same crew to the same standard.
Hawaii Conditions
Thermal movement, salt air and UV exposure are harder on a sealant joint here than in most markets. Material selection against the actual exposure matters, and so does surface preparation — the majority of sealant failures are adhesion failures, not material failures.
