Please consider using KB-Joint for the following cases;
When occurrence of random cracks is anticipated between concrete construction joints; therefore repair work may become necessary.
For construction in an area where temperature differs greatly in the daytime and at nighttime, or for construction of a structure which can be affected by external restraint
When there is a concern that repair work by sealing material may disfigure a concrete structure.
TYPE-A(water proof type)
Special butyl rubber adheres to concrete to realize waterproof effect.
Hydraulic pressure test has proved that water leakage does not occur even under hydraulic pressure of 0.5Mpa (5.0kgf/cm2), therefore applicable to underground structures.
TYPE-B(water proof type)
It is easy to be processed into any shapes.
Applicable for structures which do not require waterproof function.
