Normal humidity conditions after installation activate the self-expanding properties of the cork.  Product may be cut on jobsite to exact size required.<\/p>\n<p><strong>USES<\/strong><br \/>\nSELF-EXPANDING CORK EXPANSION JOINT is used where high resiliency is needed, such as in sewage plants, floodwalls, spillways, filtration plants, and numerous commercial and industrial applications. SELF-EXPANDING CORK EXPANSION JOINT is especially desirable where a constant friction-fit is required.<\/p>\n<p><strong>FEATURES\/BENEFITS<\/strong><\/p>\n<ul>\n<li>High resiliency with excellent recovery after compression.<\/li>\n<li>Protects against water infiltration when properly sealed.<\/li>\n<li>Easy to handle and install.<\/li>\n<li>Offers isolation capabilities.<\/li>\n<\/ul>\n<p><strong>PACKAGING<\/strong><\/p>\n<table width=\"79%\" border=\"1\" cellpadding=\"3\" cellspacing=\"0\">\n<tbody>\n<tr>\n<td width=\"40%\">Thickness Widths<\/td>\n<td width=\"23%\">Slab<br \/>\nWidths<\/td>\n<td width=\"37%\">Standard Lengths<\/td>\n<\/tr>\n<tr>\n<td height=\"59\">12.7 mm (\u00bd&#8221;)<br \/>\n19.1 mm (\u00be&#8221;)<br \/>\n25.4 mm (1&#8243;)<\/td>\n<td>610 mm (24&#8243;)<\/td>\n<td>.91 m (3&#8242;)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<br \/>\n<strong>SPECIFICATIONS <\/strong><\/p>\n<ul>\n<li>AASHTO M 153, Type III<\/li>\n<li>ASTM D 1752, Type III<\/li>\n<li>Corps of Engineers CRD-C 509, Type III<\/li>\n<li>FAA Specification Item P-610-2.7<\/li>\n<li>Federal Specification HH-F-341 F, Type II, Class C<\/li>\n<\/ul>\n<p><strong>APPLICATION <\/strong><br \/>\nThe type of control joint and spacing used will vary with each project according to the type of structure, climatic conditions, and anticipated stresses in the concrete. Thinner joints of 6.4 mm (1\/4&#8243;), 9.5 mm (3\/8&#8243;), or 12.7 mm (1\/2&#8243;), spaced at frequent intervals, offer greater control than thicker joints spaced at greater intervals. The basic objective is to provide ample room for the concrete to expand or contract without creating damaging stresses. Expansion joints should be positioned against forms at interrupting objects or columns and against abutting structures prior to the placement of the concrete. SELF-EXPANDING CORK EXPANSION JOINT should be recessed 12.7 mm (1\/2&#8243;) below the concrete surface to accept the joint sealant. SELF-EXPANDING CORK EXPANSION JOINT should be installed in a concrete joint within 24 hours of pouring.  The moisture present in the concrete and the heat of hydration is typically sufficient to cause the product to fully expand.  NOTE: When installed in existing concrete, it will be necessary to apply clean, hot water (&gt;82.2\u00b0 C) to the exposed edges of the cork to facilitate expansion.  A pressure washer capable of producing hot water or a steam cleaner may be used to produce the hot water.<\/p>\n<p>DECK-O-SEAL<sub>\u00ae<\/sub>, <a href=\"https:\/\/can.wrmeadows.com\/pourthane-ns-canada\/\">POURTHANE NS<\/a>, <a href=\"https:\/\/can.wrmeadows.com\/pourthane-sl-canada\/\">POURTHANE SL<\/a>, and <a href=\"https:\/\/can.wrmeadows.com\/sof-seal-canada\/\">SOF-SEAL<sub>\u00ae<\/sub><\/a> are suitable sealants for horizontal applications of SELF-EXPANDING CORK EXPANSION JOINT.
