Protect Concrete Expansion Joints with W. R. MEADOWS’ Cold-Applied Joint Sealants
W. R. MEADOWS provides complete joint sealing and cracking capabilities via its complete line of cold-applied joint sealants.
Why Choose W. R. MEADOWS Cold-Applied Joint Sealants
Concrete expands and contracts with temperature and moisture changes that can cause unsightly cracks and deterioration of the concrete if these inevitable climate fluctuations are not anticipated during the initial concrete placement. In order to prevent these stresses, predetermined locations that utilize expansion joints allowing for concrete movement are necessary to incorporate.
W. R. MEADOWS is an innovator in concrete expansion joint technology including several product patents, some dating back as far as 75+ years that are still widely used in the concrete construction market.
In order to properly install expansion joints, joint sealants are necessary to protect these man-made junctions. The expansion joint should be installed below the concrete surface to accept a joint sealant which will provide for maximum protection from water infiltration and weathering, in addition to keeping the joint free from incompressibles.
W. R. MEADOWS offers a variety of premium-grade cold-applied joint sealants to get the job done.

SOF-SEAL®
Cold-Applied, Low-Modulus Horizontal Joint Sealant
Cold-applied SOF-SEAL low modulus horizontal joint sealant is a premium-grade, pourable, two-component sealant composed of a special combination of polymeric compounds that provides outstanding performance in both Portland cement and asphalt concrete. Once properly mixed and applied, it cures within two hours to a soft, highly flexible, rubber-like material that is capable of maintaining a sealed joint or crack over a wide temperature range. SOF-SEAL does not track in the summer and will not become brittle at temperatures as low as -20° F (-29° C). It remains soft, flexible, and pliable in the joint, even after repeated freeze/thaw cycles. SOF-SEAL offers excellent elongation, high resiliency, tenacious bonding power, and excellent longevity. This self-leveling sealant requires no special application equipment and can easily be poured into cracks and joints.
USES
SOF-SEAL is a versatile pavement sealant suitable for either large- or small-scale sealing. It is excellent for crack repair and preventive maintenance sealing projects. It is ideal for use when a maintenance group doesn’t have a melter, or where it is not practical to fire up and repeatedly move melter-applicator units (small-scale sealing projects). Typical applications include the sealing of expansion and contraction joints, longitudinal joints and random cracks in concrete pavements, reflective and random cracks in asphalt paving, and asphalt-to-concrete shoulder joints. It is also ideal for high-sheer bridge joint applications. In addition, SOF-SEAL can be used as a pitch pan sealant.
