ECA Swellable Waterstop is a high-quality hydrophilic bentonite strip waterstops are designed for sealing concrete construction joints or existing concrete. They have a free swelling capacity of up to 400%. When used in vertical applications, it’s recommended to use a metal net for added support.
ECA Swellable Waterstop can be applied against existing concrete and are simply installed by nailing.
In contact with water, ECA Swellable Waterstop react and swell to form a compression seal.
ECA Swellable Waterstop are suitable for installation in contraction and construction joints.
ECA Swellable Waterstop are used primarily for foundation walls, slabs, slabs-on-grade, precast wall panels, manholes, pipe connections, box culverts, utility and wet wells, and potable water tanks.
• Easy application and jointing methods
• Maintains a reliable seal even in wet conditions
• Can withstand high hydrostatic pressures
• Retains original shape after repeated and contraction; after 3 dry/wet cycles (MFPA certificate)
• Swell in contact with water to form an effective compression joint
• Has good resistance to a wide range of chemicals
