What are waterstops in construction?

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. Waterstops are grouped in two distinct categories.

Where are waterstops required?

Waterstops are highly demanded in locations where the construction joints are common: The transition area between the horizontal and vertical concrete components. Long length wall areas, where two or more formwork is required for casting.

What is PVC waterstop?

PVC Waterstop FAQ Embedded in concrete, PVC Waterstops span the joint to form a continuous, watertight diaphragm that prevents the passage of liquid through the joint. The waterstop must be properly selected and installed to accommodate joint expansion, contraction, and other longitudinal and transverse movements.

What is a waterstop and why is it used?

Waterstops are used to create watertight seals in concrete construction projects. Because almost all concrete buildings feature seams and joins where the poured areas meet, a waterstop needs to be included to ensure the construction or expansion joints remain impenetrable to water.

What is water stop strip?

Waterstop-Strip is a strip applied hydrophilic rubber swelling waterstop for use in all kinds of cast-in-place concrete construction joints, as well as steel, concrete and thick-walled PVC (minimum 1/8”) pipe penetrations.

What is Construction Joint in concrete?

A construction joint is a type of concrete joint that is used when a new section of concrete is poured adjacent to another concrete section that has already set. The purpose of a construction joint is to allow for some horizontal movement, while being rigid against rotational and vertical movement.

What is a water stop in a shower?

Waterstop is an easy-to-install shower drain, thanks to its large pre-assembled sealing membrane (Water Protection System). This results in the complete waterproofing of your shower area without the need for additional sealing compounds besides tile adhesive.

How does PVC waterstop work?

Hydrophilic waterstops are adhered directly to the surface of the first concrete pour in preparation for the second concrete pour to form the joint area. The material in the strip reacts with water and swells to form a positive watertight seal in the concrete joint.

What is the use of PVC water stopper?

PVC water stopper are highly resistant to corrosion, so they are widely used for waste water treatment plants. PVC water stopper are widely used for bridges, dams, culverts and tunnels. PVC water stopper are suitable for many concrete structures because of high tensile strength.

How do I connect to waterstop?

Waterstops are generally connected by two methods. One is the cold joint method for cold bonding with rubber adhesive, and the other is the hot joint method for welding joints with hot melt machine or hot melt knife. Flatten and rough two joints, and then apply a thin layer of sealant.

What is the function of construction joint?

What does waterstop stand for in construction category?

Join now! Waterstops or waterbars are premanufactured joint filler used to prevent the transmission of water through the construction joint.

What do you need to know about waterstops?

Polyvinyl chloride (PVC) dumbbell waterstops with cured concrete extending onto flange that should be removed prior to next slab edge pour. A waterstop is a material embedded in the concrete, with the singular purpose to obstruct the passage of water through the joint.

What are waterstops and what do they do in concrete?

Download the PDF version of this article. A waterstop is usually a section of flexible, waterproof material placed at any joint in concrete to prevent the passage of water. There are several kinds of waterstops. Rubber waterstops are resilient, stay firmly locked in the concrete and movement due to settlement, and do not reduce joint efficiency.

When do you need waterstops for construction joints?

Waterstops are highly demanded in locations where the construction joints are common: The transition area between the horizontal and vertical concrete components. Long length wall areas, where two or more formwork is required for casting Situations when concrete placement is paused or stopped for some reason
