Introduction of Hydrophilic water stop
Hydrophilic water stop is made from water-swelling rubber water line to the basis of the ordinary rubber
waterstop. The product will swell when contacted with the structures. As a result, the tightness is fastened between the water stop and water-proof performance is improved and the problem of circle seepage which puzzles people in a long time is solved. This series of products have been used widely in some key projects and have gotten excellent results.
 

Features of Hydrophilic water stop
Waterproof wire adopted water-swelling rubber which will be self-swelling when contacted with water. So under the function of waterproof wire ,the concrete and water can seal better, and waterproof performance can be more excellent.The sections divided into high-strength area, water-proof area and the installation area can take unequal thickness structures according to the unique function of every area. So each part of the sections can get uniform and reasonable force.Telescopic holes' outer wall is plane; formwork folder system contact surface is large in construction and difficult to dislocation.Setting hole designed on the installation area is convenient to fix with the nearest steel bar, difficult to move , construction easily and install firmly.
 


Rubber water-stop bailey, mainly is suitable for the deformation seam in B; Suitable for construction joints with water stop, S; Apply to have special aging resistant requirements of seams with water stop with J said. Welcome the masses of customers to use our company's series rubber water-stop effect and principle of rubber water-stop product quality achieved GB18173.2-2000 requirements of the buried in the type of rubber water-stop back rubber water-stop is using rubber high elasticity and the characteristics of compression deformation, elastic deformation under various load, thereby a fastening sealing, prevent the leakage, seepage and shock absorption effect of structures.
