Everlastic® Masonry Control Joints

Everlastic® Masonry Control materials are designed to prevent destructive cracking in masonry that results from temperature, drying shrinkage, differential movement of structural members, and settling of foundations.

Williams’ materials also seal out moisture and cold air.

SLOT SEAL STANDARD 2015-3
A shear lug to provide shear control and vertical control for expansion/contraction of masonry walls. Manufactured of high-grade synthetic rubber compounds.

Polymer:

• Blended EPDM/SBR/CR
