Bridge expansion joint sealants are designed to maintain the connection between different parts of a bridge, safely absorbing expansion caused by temperature changes, building material shrinkage, and vibrations from traffic, foundation settlement, or seismic activity. If not properly sealed, the performance of bridge expansion joints can be unpredictable. Therefore, careful selection of expansion joint sealing systems is crucial for improving the reliability of bridge structures. Factors such as materials, environment, and potential risks should be considered during selection.

Polyurethane Expansion Joint Sealant
Polyurethane sealant, with its high elasticity, strong weather resistance, easy application, and excellent adhesion, is an ideal choice for sealing bridge expansion joints. Tengyu’s best-selling sealant recommendation is TP620 Road Bridge/Airport Runway Polyurethane Sealant.
- Chemical Resistance: Most bridges are built for vehicular traffic. This means that bridge joint sealants are likely to come into contact with fuel and its volatiles.
- Flexibility: Expansion joints absorb displacement caused by various factors.Therefore, the sealant must be flexible and able to achieve elastic bonding and sealing.
- One-time molding, dries instantly.
- Good adhesion to concrete materials.
- Fast painting speed.
- Good weather resistance and high durability.
- Non-polluting.
- Paintable.
