PRE-COMPRESSED HORIZONTAL ROAD AND BRIDGE EXPANSION JOINT
Willseal® 250-B is a pre-compressed, self-expanding foam joint sealant with a highway grade silicone coating engineered to perform in primary horizontal applications such as road and bridge joints. The precompressed foam core is saturated with a hydrophobic acrylic emulsion and coated with a fuel-resistant silicone sealant, allowing it to provide an optimal primary seal that is waterproof to rain and snow at the surface level.
Features & Benefits
- Dual expansion joint seal
- Designed for rapid cycling and thermal shock
- Resistant to common automotive oils/fuels and jet fuel (per FHA PL06)
- Allows rapid joint movement up to ±60% from the mean joint size
- Performs effectively in joints up to 101.6 mm wide
- Self-expands to fill the joint
- Expansion rate varies with humidity, temperature, and recent storage conditions
Applications
- Primary horizontal seal in road joints
- Primary horizontal seal in bridge joints
- Sealing for approach slabs
- Ideal where shear and rapid movement are expected
