Description of Rubber waterstop bar
The bentonite strip is a green flexible hydrophilic strip of approx. 25 x 20 mm, made of natural sodium bentonite clay and synthetic rubber. The bentonite strip comes in lengths of approx.
5 meters. Due to shrinkage of the drying concrete, small cracks and voids will appear in the construction and cold joints, through which water can penetrate. In contact with water the green bentonite strip will swell approximately 400 % of its original dry volume. The expansive clay mass will seal the cracks and small voids in the joint. The first expansion is delayed to prevent the strip from expanding to soon in contact with rainwater during the installation.
Features of Rubber waterstop bar
Rubber waterstop bar has the following features: 1. The product prepared in concrete construction joint, post-cast seam on the interface of the secondary concrete (was) under the condition of concrete after water expansion can thoroughly clogging aperture. 2. The expansion rate is slow, strong water pressure resistance, suitable for the rainy season and water rich in construction site. 3. The construction method is simple, according to the construction method, can have the effect of the waterproof impermeability. 4. As the inorganic mineral raw material, the main resistance, corrosion resistance, no pollution and so on characteristics.
Installation method of Rubber waterstop bar:
1. After being hardened concrete construction joint interface, sweep off scum, dust, debris, etc., and solid base. 2. Construction and horizontal construction joint of post-cast strip, will stretch along the construction joint direction of water stop, using its own direct bonding paste in the middle position of construction joints, lap joint is not less than 5 cm, there shall not be a breakpoint. Should be reserved for the facade construction joint positioning shallow slot, will be embedded in the reserve tank of water stop, if there is no reserved slot, high strength steel nail fixed can also be used, and by using the self-adhesive, paste on the construction joint interface directly, through isolation paper uniform compaction. Article 3. The water stop the fixed end, tore down the isolation of paper can be under the pouring concrete. 4. Paste parts of water stop the opening transverse installation can be chosen. Article 5. To make the water stop fixed firmly, every 1 m high strength steel nail with horizontal seam, fixed, the vertical seam every 0.5 m high strength steel nail with fixed.
