A typical water stopper consists of two identical halves on either side of a central bulb. Increased path length made possible by this design effectively diverts any water that could try to enter past the water stopper's edge. Water stoppers increase their efficiency in preventing water penetration and preserving the integrity of the structures they are applied to by offering this extra extension. Sandhya Enterprises is dedicated to producing water stoppers of the highest calibre that adhere to industry requirements and provide dependable water barrier solutions.

Sika Waterbar® made from PVC-P can be used as flexible waterstops and are designed for the sealing of movement (expansion) and construction joints in new watertight concrete structures.Non-toxic materials are required to make the water bars for water tanks and water sumps used to contain drinking water. PVC water stopper, also called PVC water stop seal or PVC water stop belt, is manufactured from superior grade polyvinyl chloride resin and various chemical additives by the process of mixing, granulating and extrusion. It is used to prevent leakage and permeation in construction joint by taking full advantage of Our water stoppers are specially manufactured using an anti-ageing customized plastic compound. Additionally, it has PVC as a base polymer. These water stoppers offer several advantageous properties, such as high elasticity and tensile strength, immunity to corrosion, ensuring long-lasting durability even in harsh environments, and excellent weather resistance. They can withstand exposure to various chemicals, including acids, alkalis, metals, salts, and other corrosive substances. Other properties include lower water absorption, reducing the risk of water permeation through the joint. With their high hydrostatic pressure withstanding capacity, the water stoppers effectively resist water pressure, maintaining a watertight seal.

SikaSwell P are also swellable joint sealing profiles, see data sheet for further information. NatCem Waterbar A waterstop is an element of a concrete structure, intended to prevent the passages of fluids (such as water) when embedded in and running continuously through concrete joints.This is the most common type. It features a high tensile strength, high resistance to acids, diesel oil, chlorinated water and other chemical liquids. They do no discolor the concrete nor does any electrolytic action occurs with the surrounding reinforcement. It has excellent inherent elasticity and impermeability. PVC waterstop is rather easy to install by tethering the outer flanges to adjacent a reinforcing bars. It is available in a range of different types, shapes and sizes to suit different types of structures and joint sealing applications.
