The self-sealing properties of bentonite are encased within a hydration-resistant core providing both extreme free swell properties as well as delayed swell properties. The multilayered structure with polypropylene fabric and strong tear-resistant netting provides for additional strength and structure. WATERSTOP EC will provide superior performance over the life expectancy of the structure.<\/p>\n<p><strong>USES<\/strong><br \/>\nWATERSTOP EC is used to seal non-moving construction joints in concrete footings, walls, floors, tunnels, and parking and plaza decks and to prevent water migration. The product can also be used around pipes and other types of penetrations.\u00a0 WATERSTOP EC has superior performance when used under conditions of extreme water head.<\/p>\n<p><strong>FEATURES\/BENEFITS<\/strong><\/p>\n<ul>\n<li>Provides both extreme free swell properties as well as delayed swell properties.<\/li>\n<li>Provides additional strength and structure.<\/li>\n<li>Provides superior performance over the life expectancy of the structure.<\/li>\n<li>High expansion properties seals open areas in concrete surface.<\/li>\n<\/ul>\n<p><strong>PACKAGING<\/strong><br \/>\nStandard rolls sizes:<br \/>\n12.7 mm x 25.4 mm x 4.6 m (1\/2&#8243; x 1&#8243; x 15&#8242;)<br \/>\n19.1 mm x 25.4 mm x 4.6 m (3\/4&#8243; x 1&#8243; x 15&#8242;)<\/p>\n<p><strong>STORAGE AND HANDLING<\/strong><br \/>\nProtect from moisture. Store on skid or pallet; cover with polyethylene or tarp.<\/p>\n<p><strong>APPLICATION<\/strong><br \/>\n<strong>Surface Preparation \u2026 <\/strong>Ensure that surface is free from protrusions and debris.\u00a0\u00a0\u00a0 If there are voids in the surface, fill with <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/clay-tite-mastic-canada\/\">CLAY-TITE MASTIC<\/a> from W. R. MEADOWS prior to installation of waterstop.<\/p>\n<p><strong>Application Method \u2026 <\/strong>WATERSTOP EC is designed for use on vertical and horizontal construction joints with a minimum of 50.8 mm (2&#8243;) of containment. CLAY-TITE MASTIC will fill voids in rough concrete and provide additional adhesion to the concrete while preventing water or concrete from seeping under WATERSTOP EC.\u00a0 If surface is troweled smooth, lay a 3.2 &#8211; 6.4 mm (1\/8&#8243; &#8211; 1\/4&#8243;) bead of CLAY-TITE MASTIC along the joint. Surfaces to receive the hydrophilic waterstop cannot have protrusions greater than 12.7 mm (1\/2&#8243;).\u00a0 Press WATERSTOP EC into uncured CLAY-TITE MASTIC and nail every 381 mm (15&#8243;) on center.\u00a0 Attach WATERSTOP EC with a washer nail [25.44 mm (1&#8243;) shank] with washer [15 &#8211; 23 mm (5\/8&#8243; &#8211; 13\/16&#8243;)]. Butt ends for a continuous application.<\/p>\n<p><strong>PRECAUTIONS<\/strong><br \/>\nKeep WATERSTOP EC dry; protect from exposure to the elements. WATERSTOP EC should be installed at least 2&#8243; (50.8 mm) from the face of the concrete.\u00a0 In areas of high salt concentration, a water sample may be required to determine site suitability for installation.<\/p>\n<table width=\"100%\" class=\"table\">\n<tbody>\n<tr>\n<td width=\"27%\"><strong>Property<\/strong><\/td>\n<td width=\"23%\"><strong>Test Method<\/strong><\/td>\n<td width=\"50%\"><strong>WATERSTOP EC Results<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Weight<\/td>\n<td><\/td>\n<td>0.4 kg\/m (0.25 lb.\/linear foot)<\/td>\n<\/tr>\n<tr>\n<td>Tear Strength: Membrane<\/td>\n<td>ASTM D1004<\/td>\n<td>12.7 mm (1\/2&#8243;): 333 N (75 lb.)<br \/>\n19.1 mm (3\/4&#8243;): 500 N (112 lb.)<\/td>\n<\/tr>\n<tr>\n<td>% Elongation at Break<\/td>\n<td>ASTM D638<\/td>\n<td>&gt;150%<\/td>\n<\/tr>\n<tr>\n<td>Unrestricted Expansion<\/td>\n<td><\/td>\n<td>300% over 4 days<\/td>\n<\/tr>\n<tr>\n<td>Installation Temperatures<\/td>\n<td>ASTM D746<\/td>\n<td>-25\u02da to 50\u02da C<\/td>\n<\/tr>\n<tr>\n<td>Freeze\/Thaw Cycles<\/td>\n<td><\/td>\n<td>No effect before or after installation.<\/td>\n<\/tr>\n<tr>\n<td>Resistance to Hydrostatic Head<\/td>\n<td>ASTM D751, Procedure A<\/td>\n<td>30 m (100&#8242;) of water<\/td>\n<\/tr>\n<tr>\n<td>Vapor Permeability<\/td>\n<td>ASTM D5084<\/td>\n<td>1 x 10<sup>-9<\/sup> cm per sec<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>MASTERFORMAT NUMBER AND TITLE<\/strong><br \/>\n03 15 13 &#8211; Concrete Accessories &#8211; Waterstops<\/p>\n<p>2025-10<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/can.wrmeadows.com\/pics\/foot-can.jpg\" alt=\"\" width=\"640\" height=\"98\" align=\"BOTTOM\" border=\"0\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/can.wrmeadows.com\/pics\/footer-can.jpg\" alt=\"warranty\" width=\"614\" height=\"212\" align=\"BOTTOM\" border=\"0\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>WATERSTOP EC is a multilayered, bentonite-based hydrophilic waterstop for construction joints.
