Provision Living (St. Louis, MO)
HBD Contracting was in search of an expansion joint system to accommodate the seismic opening between a new elevator tower and and the existing building that houses the Provision Living Center for the aged in St. Louis. After a visit to EMSEAL's website HBD looked to the Seismic Colorseal as a possible candidate and was linked to Shield Systems, the local rep firm for technical assistance.
A visit to the jobsite by a Shield sales consultant confirmed the Seismic Colorseal to be a perfect match for the application. The Colorseal product could accommodate the ranging in the masonry to masonry joint opening as it is manufactured in 1/4" increments for such challenges. In addition, the joint opening made a change in plane and continued over the top of the tower and down the back side of the elevator structure. Again, the Seismic Colorseal could be installed to provide a seamless continuous joint from start to finish.
The average opening was approximately 4 1/2" and was installed quickly by two carpenters never before experienced in EMSEAL foam sealants. A testimony for the simplicity of the product and user friendliness of the product.
The installation starts with removal of the factory rapping which holds the foam in compression. A release film is removed from the edges of the foam and the material is slipped into the joint. While the foam is acrylic impregnated, making it tacky to the touch, it also contains an extra adhesive on one edge which allows the mechanic to adhere the product to one side of the joint opening during placement. Shortly after insertion the joint swells and forms a permanent seal due to a combination of the acrylic impregnation and the back pressure caused after expansion. Following the expansion process a bead of Dow Corning 790 silicone sealant is added to the joint interface to form the final seal.
HBD was amazed at the ease of application and pleased with the aesthetic finish of the non-invasive water tight joint. Another satisified customer, another successful application for Seismic Colorseal!
