Rubber swell bar putty slow type of water swelling strip hydrophilic waterstop rubber bar for construction joints

Waterproofing for subterranean / below ground and water retaining / water containing structures at construction joints and movement joints (also referred to as expansion joints or contraction joints). Profiled PVC and swellable waterstops are important for integral sealing of construction joints and movement joints in concrete cast in-situ.

The swellable hydrophilic waterbars / waterstops are easy to install and good for problem solving in situations where a conventional waterstop would require complex shuttering. As their description suggests they swell when water comes into contact with it. So if the water bar is placed in the centre of a construction joint, if water begins to track through the joint and gets as far as the centre, the waterbar swells upon contact pushing against the concrete, preventing the water from travelling any further. Typical uses include concrete basement structures, secant piled and diaphragm walled basements, pile caps and casting against old concrete. Swellable waterstops can provide simple solutions to detailing pipe entries, construction joints in the vertical plane and to kicker joints. They can be linked to flexible PVC waterstops and swellable hydrophilic sealant to give an appropriate effective combination of waterstops to maintain network continuity in waterproof concrete construction.
