FAQs: Expansion Joint Repair
What materials are used to fill and seal expansion joints?
- Common Materials:
- Polyurethane Sealant: Durable and flexible, ideal for high-movement joints.
- Silicone Sealant: Waterproof and UV-resistant, suitable for outdoor or wet areas.
- Polysulfide Sealant: Resistant to fuels and chemicals, often used in industrial settings.
- Foam Backer Rods: Compressible filler for large gaps (e.g., 4-inch gaps) before applying sealant.
- Best Filler for Concrete: Self-leveling polyurethane or silicone for narrow joints; foam-backed sealant for wider gaps.
How do you repair or treat damaged expansion joints?
- Repair Process:
- Clean the Joint: Remove debris, old sealant, and loose material.
- Insert Backer Rod: For gaps >0.5 inches, use foam backer rods to support the sealant.
- Apply Sealant: Fill with polyurethane, silicone, or polysulfide sealant. Smooth the surface.
- Cure: Allow 24–48 hours for the sealant to set.
- Large Gaps (e.g., 4 inches): Use foam backer rods combined with flexible sealant to accommodate movement.
How do expansion joints work, and why are they important?
- Function: Expansion joints absorb thermal expansion/contraction and structural movement to prevent cracks.
- Key Features:
- Allow horizontal/vertical movement without damaging adjacent materials.
- Require flexible, durable sealants to maintain integrity over time.
