Introduction of swell bar:

It is new type of seal material. It is just like a rubber putty which will expand when water go on. It is used to resolve sealing problems of joint settlement of concrete structures. It is used as a water stopper bar .unicorn chemical company is best provider for swell bar.

Types of water stop or swell bar:

There are five types of water stopper used in market gen below:

1- Rubber water stopper:

• Natural rubber and various kind of synthetic rubber use as the main raw material adding many additives and fillers and plastication, mixing ,pressing and forming.
• has good elasticity
• wear resistance
• aging resistance
• tensile property
• adapt to deformation ability strong
• reliable for water stop in concrete
• used in basements, dams, reservoir, swimming pools , and roofing.

2- Hydrophilic swell bar:

• Water line to the basis of the rubber water stop
• Being swell when contacted with structures
• Tightness is fasten between them
• improves the water proofing quality of swell bar
• circle seepage problem resolved
• provide limited amount of movement within the concrete joint
• Used to build subway, culverts and tunnels and other underground construction.

3- Steel side swell bar:

• For the large deformation crack the joints
• Extended way slow seepage rate
• Used for good adhesion between galvanized steel and concrete
• Make the water proof performance better
• Bear a more water stopper tension
• play a roll on sealing
• Difficult dislocation like wise mounting hole and steel plate connected to a fixed solid difficult to shift

4- PVC swell bar for concrete joint:

• Used in concrete joints to control the hydrostatic pressure
• Used After making solid concrete mixture
• Used to fill the joints
• Used to form a continuous watertight diaphragm to prevent the passing of fluids
• Must be designed and installed properly to accommodate joint expansions, contraction , lateral and transverse movements.
• To control the chemical and fluids water stopper must be compatible with concrete system
• Take less time to fixing
• Used as a sealants
• We fixed it where we want to laid the concrete slab.

5- Swelling water stop bar for concrete:

• It is just a rubber putty
• Expand on water falling on it
• Resolve sealing problems
• Widely used in rainy season construction sites or in water construction
• Most costly swell bar material
• Reliable in expansion joint of concrete project
• Used in swimming pool , sewage treatment , underground railways, tunnel and crevice ,
