What is Expansion Joint Repair?
Expansion joints are essential in any structure, allowing materials to expand and contract with temperature fluctuations and other environmental factors. However, these joints can become susceptible to leakage and seepage over time, causing damage to your building. Expansion joint repair involves sealing these joints to prevent water ingress and structural damage.
New Eversmatic: The Ultimate Solution for Expansion Joint Waterproofing
We use New Eversmatic, a high-performance sealant and gap filler based on special polymers, designed to provide an effective waterproofing solution for building expansion joint leakage. Once cured through moisture evaporation, New Eversmatic forms a durable and attractive joint sealant that provides long-lasting protection.

FAQs: Expansion Joint Repair
What materials are used to fill and seal expansion joints?
- Common Materials:

- 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.

- 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.
