Hydrophilic waterproof rubber waterstop bar for concrete joints is a kind of water absorbing strip used to seal and waterproof concrete joints. rubber waterstop bar are usually made of natural sodium bentonite and synthetic rubber.
When the rubber waterstop bar is exposed to moisture, both modified synthetic rubber and bentonite will expand in the joint.
rubber waterstop bar is a new type of waterproof material, and its waterproof effect is more reliable than that of ordinary rubber.
When the rubber waterstop bar comes into contact with water, the rubber waterstop bar will expand to about 150% - 600% of its original dry volume, and the expanded clay block will seal the cracks and small voids in the joint.
The rubber waterstop bar has the sealing and waterproof function of the elastic joint water stop material. When the distance between the two sides of the joint is increased
When it is larger than the elastic recovery rate of elastic waterproof material, the rubber waterstop bar has the characteristics of expansion in case of water. There are still rubber waterstop bar within the expansion range of the material, and the expansion body still has rubber properties, which is more resistant to water, acid and alkali. The expansion speed is slow, the water pressure resistance is strong, and the construction method is simple. It is suitable for rainy seasons and construction sites with abundant water.
In recent years, rubber waterstop bar has been widely used, and the export quantity of rubber waterstop bar is increasing every year. The construction of rubber waterstop bar is convenient.
