Adcor® 510S

Thick sectioned, conformable, hydro-expansive waterstop for preventing water entry through joints in concrete sub-structures. The conformable, hydro expansive and rubber component based 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® is a unique product that has been specifically developed to provide higher performance than conventional bentonite or swellable rubber waterstops.

Application:

• Construction joints for in-situ concrete structures.

• Casting new concrete against existing concrete.

• Floor slabs cast against diaphragm retaining walls, steel sheet piles and secant piled walls.

• Joints between floor slabs and pile caps.

• Remedial 'breaking out' of concrete.

Features/ Benefits:

• Optimized to prevent premature swelling in wet site conditions.

• Controlled volumetric expansion - reduces 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 min 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.

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 510S.

• Adcor® Adhesive MS: An adhesive for gluing Adcor 510S to smooth concrete, steel and plastic substrates.

• Pak Adhesive™: A contact adhesive for gluing Adcor 510S to smooth concrete, steel and plastic substrates.
