Description
Expansion under the influence of water with the water of water stop expansion properties of water putty and meet water swelling rubber strip.  Encounter water swelling rubber is a new special kind of rubber products. It is a combination of general rubber products performance, and can meet the expansion of the water on its own performance, is a new type of waterproof material, water stop, waterproof effect is more reliable than ordinary rubber.
 
Putty type of expansive water stop under the influence of water is a recently developed new products, it has met the special performance for the expansion of the water. Elasticity of the material in water sealing waterproof effect, when both sides joint lateral distance to elastic recovery rate of elastic waterproof material, due to the nature of the material has the water expansion. Starting and ending water in material expansion scope can still function.
 
Advantages 
1,This product can be put on the base surface of concrete construction joint directly, and the construction is convenient, simple.
2,In a few minutes after this product in water gradually expand, on the one hand, blocking all ooze water gap, on the other hand combined tightly with concrete interface, and fundamentally to cut off the water seepage channel.
3, the main body material is inorganic mineral material, so it have ageing resistance, corrosion resistance, permeability resistance function and is will not  affected by temperature and humidity changes, has reliable durability.
4, Have remarkable self-healing function, when the construction joints emergent a new  tiny crack, it can continue to swell, water stop further blocking new micro seam, automatic reinforcement waterproof performance.
5, In the process of cement mortar pouring, the bibulous rate is very small ,it will not because of the existence of the mixing water and caused concrete expansion .
6, This product after repeated ,no main  material leachingimmersion material leaching, no shivers
And the performance of expansion under the influence of water to maintain is good.



Application method
1,cast-in-site concrete construction joint, will have the construction of concrete base, chisel, the strip of water stop paper take out, in the central along the longitudinal width of construction joint, and to give pressure together, every 50 cm interface built with adhesive glue overlap and compaction, up and down with masonry nail nails.
2, concrete cracks, the crack width of each 4 cm slot, will be embedded within the seam of water stop, compaction in polymer cement paint twice.
 
 Notes
1,Paste the interface should be kept dry. Applied to the water stop gap inside may not appear.
2, And construction joint interface of water stop paste to close, stretch along the construction joint direction shall not be broken, can't be scum dust cover, etc.
3, To fully be concrete water stop parcel, parcel thickness > 5 cm.
4, After fixation of water stop before pouring the concrete, should avoid to be soaked in water for rain or construction.
5, Storage and transport of water stop, avoid damp and extrusion, should not be stacked more than
