How do you install hydrophilic waterstop?
Place several drops of a cyanoacrylate type adhesive (super-glue) on the cut ends of Hydrotite and immediately join the ends together. Hold it in position for approximately 30 seconds to allow the adhesive to set. Proper alignment and bonding of the cut ends will prevent water entering the cells of the profile.
What is a PVC waterstop?
Earth Shield® Polyvinyl Chloride (PVC) Waterstop is used as a fluid-tight diaphragm, embedded in concrete, across and along the joint, for environmental engineered concrete structures.
Where should I place my waterstop?
Joints formed between adjacent concrete pours and where mechanical elements penetrate the concrete are the most likely points of water ingress into below-grade concrete structures. To prevent this from occurring, waterstops are commonly specified and installed at every joint in the concrete below-grade.
What is hydrophilic waterstop?
Hydrophilic waterstops are elements of a concrete structure, intended to prevent moisture infiltration. Hydrophilic means “water-loving”, so these hydrophilic waterstops swell in the presence of moisture. They can be used to seal concrete joints, but also to seal formwork spacers or tie rods.
What is a waterstop angle?
A waterstop (angle) at a doorway provides the wet area outside of a shower enclosure with what is called a “maximum retained water level”. This is defined as: the point at which surface water will start to overflow out of the shower area, or in this instance the room itself.
How do you seal a concrete water tank?
INTERNAL WATERPROOFING Treating the inside of concrete tanks usually requires a positive tanking application. Liquid applied membranes are idea for this purpose. The most convenient method is to use an acrylic water based product like FLEXIPRO. The area will need at least two coats.
How does bentonite waterstop work?
The key to WATERSTOP-RX is sodium bentonite. Sodium bentonite swells when in contact with water, forming an impermeable barrier. This swelling property allows WATERSTOP-RX to form a permanent pressure seal within the concrete joint, thus eliminating water migration over or along the waterstop (see Figure 1.1).
How does a waterstop work?
Hydrophilic Waterstops 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.
Why do we use waterstop?
Waterstop is a material that is embedded in the concrete, across the concrete joint, to obstruct the passage of water through the joint. A waterstop installed in concrete joints is an important component of the overall waterproofing design.
How do you use Sika greenstreak water stops?
Sika® Greenstreak WATERSTOPS Concrete Accessories CHOOSING THE RIGHT WATERSTOP WATERSTOP BASIC USE Embedded in concrete, across and/or along the joint, waterstops form a watertight diaphragm that prevents the passage of liquid through the joint.
