Silicone Sealants for Highways, Roads and Bridges

Highways, Roads and Bridges

Silicone sealants for joints in demanding highway and bridge applications outperform organic alternatives.

Proven solutions for long-lasting protection

With a demonstrated 20-plus year life-span on highway and road sealing projects, Dow Corning puts their silicone construction expertise to work for your benefit.

Dow Corning® silicone pavement sealants are ideal for sealing a wide range of applications, such as expansion joints, transverse joints, longitudinal joints, construction joints and crack-control joints in highways, roads, bridges, bridge decks and parapet walls and other similar projects.

How can our silicone highway and bridges sealants help you?


Put the silicone advantage to work for you

Designed for use on expansion joints, construction joints and crack-control joints in concrete, Dow Corning® silicone pavement sealants:

  • Keeps water and incompressible debris out of joints to maintain their function and avoid cracks and prevents freeze-thaw damage.

  • Resist UV radiation, extreme temperatures and weather conditions.

  • Provide long-lasting sealing by accommodating extreme movement (thermal stress).

  • Exhibit excellent recovery characteristics, making them ideal for use in joints that experience a high degree of movement.

  • Outperform organic alternatives – silicones have greater UV stability and temperature and weather resistance to ensure a long life span.

  • Create long-lasting, flexible, low- to ultralow-modulus, high-elongation silicone rubber seals capable of withstanding extension of 100 percent and compression of 50 percent of the original joint width.

Available in varying product options, Dow Corning® silicone pavement sealants make it simple to find the right material for your need:

  • Easy-to-install one-part sealants or rapid-cure two-part sealants

  • Ultralow modulus sealants for joints in concrete and asphalt pavements that place very little stress on the surfaces

  • Self-leveling sealant to reduces labor costs
