Matlex - Rubber Waterstop

Concrete Structure Expansion Joint Rubber Waterstop is a special type of hydraulic cement. It is a non-corrosive, non-rusting, instantly setting compound for plugging and stopping water or fluid leaks in concrete structures or masonry surfaces. Commonly used for waterproof elements placed in the construction joints and deformation joints of foundation works of the concrete structure when pouring concrete. It has good elasticity, strong adaptability to deformation, and great waterproof performance.

Rubber waterstops, also known as rubber water stops, are classified into several types based on their materials, including natural rubber waterstops, neoprene waterstops, nitrile rubber waterstops, and EPDM waterstops. Rubber waterstops of various materials are appropriate for a variety of circumstances.

In addition, we can make rubber waterstops to customer specifications. They are commonly utilized in the construction of bridges, dams, tunnels, culverts, storage tanks, and waste water treatment plants.

Our main goal is to produce high-quality rubber products because they are essential in the construction of a superstructure's base. Not only do we want to exceed our clients' expectations, but we also want to build a product that will protect people and their money.

Applications of Rubber Waterstop

Rubber Waterstops are commonly used in concrete constructions such as dams, reservoirs, subways, culverts, tunnels, and other underground operations.

· They are commonly utilized for both moving and non-moving joints.

· Dams, bridges, tunnels, culverts, and canals all employ them.

· They are utilized in sewage and water treatment systems.

· They are used to construct retaining walls.

· They are also employed in the construction


The first stage in installing a rubber stopper in building construction is to locate the location on the wall where the rubber stopper will be installed. Drill the hole for the rubber stopper using a drill bit slightly larger in diameter than the rubber stopper. The hole should be drilled as deeply as possible into the wall so that the rubber stopper is sturdy and does not move once attached.

The rubber stopper can be fitted after the hole has been drilled. The top of the rubber stopper should be flush with or slightly above the surface of the wall. A little amount of silicone caulk can be used to seal around the edge of the rubber stopper if necessary.

Taking care of your home is one of the most important aspects of owning one. This includes both inside and outside maintenance and upkeep. Water stoppers are a common fixture in many homes, but they frequently require maintenance to stay in good working order. Cleaning Rubber Water Stoppers In order to keep rubber water stoppers looking their best and functioning properly, they must be cleaned on a regular basis. Many rubber products can be cleaned with a soft brush and warm soapy water. Rubber water stoppers, on the other hand, are more likely to grow mold and mildew. As a result, a product designed specifically for rubber products must be used. This rubber cleaning product can be purchased at any hardware or home improvement store.
