Williams Masonry Control Joint materials are made of quality elastomers, meeting ASTM material standards.  These control joint gaskets provide more than one functional feature for a given application.  These custom designed seals furnish an excellent seal and function as a second line of defense when sealants fail from in-service use.  These sealants will shed water and will reduce sound and thermal transmission.   Shear loads from wind are transferred to the concrete masonry units with our gaskets in control joints.

The Neo Seal IV gasket is used as a joint filler, a back -up rod and a compressible material in brick expansion joints.  This multi-functional product provides excellent control during installation because one component is used instead of two, minimizing labor costs at each expansion joint.   Neo Seal IV is an expanded closed cell neoprene material, extruded gasket, with four connected tubes.  The elastomer is non-absorbent and is inert to heat, cold and atmospheric acids.  The specially formed tubes compress to approximately 3-1/4" in overall width when installed in a conventional 3/8" brick expansion joint.   This gasket provides an effective seal against moisture entering the joint causing frost damage.

The Williams-Goodco brick vent is an injection molded vent made from flexible polyvinyl chloride in an offset "T" shape. When inserted in vertical mortar joints between two bricks the slotted leg of the vent allows air to pass in and out allows water to weep out and prevents water from penetrating in.

Williams Masonry Control Materials are designed to prevent destructive cracking in masonry (from temperature and drying shrinkage, differential movement of structural members and surrounding masonry, settling of foundations, etc.) While stress relieving masonry, Williams? materials also seal out moisture and cold air at a reasonable price.
