Actistop - Waterstop

ActiStop is a high-swelling hydrophilic strip waterstop and is a formulated blend of sodium bentonite and butyl rubber. ActiStop is an active waterstop which reacts with water to seal construction joints within concrete. The seal resists hydrostatic pressure, stopping the passage of water through the joint. ActiStop is designed to replace passive PVC/ rubber waterbars, without the need for pre-formed intersections, split forming or seam welding.

Features and benefits:

• Non-dimensional swell allows complete injection into surrounding voids.
• Conformable – can be applied to a range of irregular substrates.
• Resists in excess of 9 bar (90 m) hydrostatic pressure.
• It swells many times more than its dry volume to form an impenetrable gel.
• Simple butt-jointing on site application.
• Reproducible swell after wet-dry cycle.
• Unaffected by freeze/ thaw cycling.
