Sika Greenstreak Waterstop Ribbed Centerbulb, 4" H x 3/16" W, 100' L Roll

Embedded in concrete, across and/or along the joint, waterstops form a watertight diaphragm that prevents the passage of liquid through the joint. Sika Greenstreak waterstops are precision engineered for vertical and horizontal expansion joints between cast-in-place concrete units where conditions may subject the concrete to hydro-static pressure or moisture seepage. They are manufactured with the highest quality PVC to provide the strongest tensile strength and elongation capabilities possible with a superior resistance to alkalis, acids, ozone and waterborne chemicals.

• Ribbed with centerbulb shape accommodates lateral, transverse, and shear movement
• 4-inches high x 3/16-inch wide x 100-foot long roll
