Services Expansion Joint Filling
Expansion Joint Filling
Flexible sealing of structural expansion joints that accommodates building movement and prevents water leakage through gaps in roofs, podiums and concrete slabs.
Expansion joint filling is essential to accommodate building movement and prevent water leakage through structural gaps. It ensures flexibility, durability and long-term protection for roofs, podiums and concrete slabs.
Procedure:
- Joint preparation — clean out the expansion joint and remove any old, failed filler.
- Backer rod — insert a backer rod or filler to set the correct sealant depth and support.
- Flexible sealant — apply a flexible polyurethane sealant evenly along the full length of the joint.
- Smooth finish — tool the sealant smooth so it bonds well and flexes with the building’s movement.
