Adcor® 500S

Thick sectioned, conformable, hydro-expansive waterstop for preventing water entry through joints in concrete sub-structures. The conformable, swellable polymer butyl rubber waterstop strip expands in contact with water and when fully encapsulated by poured concrete, the expansive forces form a seal against concrete faces. The seal resists hydrostatic pressure, stopping water from entering sub-structures. Adcor® has been specifically developed to provide higher performance than conventional bentonite or swellable rubber waterstops.

Features and benefits:

• Controlled volumetric expansion reduces the risk of concrete spalling.
• Conformable can be installed onto a variety of irregular substrates.
• Retains cohesive strength at both original and expanded volume.
• No need for protective steel mesh.
• Resists at least 6 bar (60 m) hydrostatic pressure.
• Volumetric expansion minimum 100% in cement water.
• Simple overlap jointing on site.
• Reproducible swell after wet-dry cycling.
• Can be easily joined to GCP PVC waterstops at movement joints.
• Unaffected by freeze or thaw cycling.

System components:

Can be used in conjunction with:

• Adcor® Mastic: A hydrophilic mastic for use as a bedding bead on irregular concrete surfaces prior to the application of Adcor 500S.
• Adcor® Adhesive MS: An adhesive for gluing Adcor 500S to smooth concrete, steel, and plastic substrates.
• Pak Adhesive™: A contact adhesive for gluing Adcor 500S to smooth concrete, steel, and plastic substrates.
