PVC Waterstop V160X30M – Expansion Joint

Skyhat® PVC Construction waterstops are essential components used in concrete structures to prevent water passage through joints, ensuring the integrity and longevity of the structure. These devices are typically made from materials such as PVC, rubber, or metal and are strategically placed at construction joints, expansion joints, or anywhere two concrete surfaces meet. Their primary function is to block the path of water, thus protecting the structure from water ingress that could lead to corrosion, structural damage, or mold growth. Waterstops are crucial in various applications, including dams, water treatment plants, tunnels, and basements. Proper selection and installation of waterstops are vital to their effectiveness, requiring consideration of factors such as the type of joint, expected movement, and environmental conditions. By providing a reliable barrier against water penetration, construction waterstops play a vital role in maintaining the durability and safety of concrete structures.

The Requirements of a Waterstop

1 Installation must be easy so as to ensure a close and smooth joint.

2 A smooth profile is essential for the intimate compaction of fine quality dense concrete on its surface.

3 Resistance of maximum stress at the anchorage points consistent with their distant location from the joint where the section spans.

4 High level of rigidity facilitate installation consistent with economy and other necessary qualities.

5 Centrally placed waterstop: Sections cast in slabs or walls in concrete structure can prevent water seepage. They fit to water retaining structures and in walls and slabs where pressure differentials may occur, i.e. reservoir walls. They also fit to joints in suspended slabs, ground floor slabs, vertical wall joints and lift joints.

6 Externally placed waterstop: It fits to basement and foundation construction where it support firmly against back pressure, i.e. in or beneath water excluding structures where it is firmly supported by the base formation.
