What are hydrophilic strips?
What are hydrophilic strips?
The hydrophilic strips constitute the primary joint seal. Special hydrophilic connectors are incorporated during installation to divide the channel system into individual sections. This special installation method allows localized remedial injection in case of any later leakages.
What is a 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 bentonite waterstop?
Bentonite waterstop is a kind of hydrophilic water sealing product coming with incomparable durability and higher water absorption no less than 300%. Quality sodium bentonite clay and rubber materials. Moisture activated. Strong, durable with high cost effectiveness.
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.
How do hydrophilic strips work?
HYDROPHILIC GASKETS SWELL in contact with water. During this process the SikaSwell® waterstop exerts pressure on the surrounding surfaces and seals the construction joint against water penetration. SikaSwell® products are characterised by a reliable capacity and a reversible swelling process.
What do you mean by hydrophilic?
: of, relating to, or having a strong affinity for water hydrophilic colloids swell in water and are relatively stable soft contact lenses are made of hydrophilic plastic, which absorbs water — compare lipophilic, lyophilic, oleophilic.
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).
What is in bentonite clay?
Bentonite clay contains natural minerals such as calcium, magnesium, and iron, which may provide additional benefits. Bentonite clay forms from volcanic ash. It gets its name from Fort Benton in Wyoming, where it occurs in large amounts.
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 a 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 the function of the hydrophilic strip?
The hydrophilic strip constitutes the and systematic regrouting of any defects. civil engineering works. from vulcanized elastomers, that swells upon contact with water. initial swelling during installation.
How are hydrophilic Waterstops used in concrete construction?
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 can A waterstop strip be used for?
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 makes a rascotight QVE hydrophilic strip waterproof?
RASCOtight QVE Hydrophilic Strip is a waterproofing strip, made from vulcanized elastomers, that swells upon contact with water. The hydrophilic strip is finished with a protective coating to delay
