Introduction of swell bar:
It is new type of seal material. Swell Bar 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 ,
