High tensile strength
High tensile strength, high plane torsional modulus, good creep resistance, stable chemical properties
High coefficient of friction
High resistance to mechanical damage and durability, and large friction coefficient with sand and stone
Bearing capacity is strong
It can improve the bearing capacity of the foundation (generally more than 40%) and increase the diffusion Angle (from 38 degrees
to 50 degrees on average).
The material soft
Convenient transportation, laying, easy lap positioning, saving project cost
The compactness
It has a strong self-water retention performance
High and low temperature resistance
It has excellent waterproof performance
Because sodium-based bentonite is inorganic material, even after a long time or changes in the surrounding environment, will not occur aging or corrosion phenomenon, so the waterproof performance is durable.
Easy to transport
Packaging, transportation, construction and storage are convenient according to requirements.
Introduction of water contact expansion waterstop.
Water-induced expansion waterstop is the use of its production and processing of this feature, can play a solid sealing role, in the external extrusion produces elastic deformation, can prevent the building structure seepage, so as to achieve the role of shock absorption buffer, many engineering design requirements, including civil construction, soil and water structure between the expansion degree of this one, and the problem of waterproofing and seismic protection also exists, the use and installation of water-induced expansion waterstop can be solved The existence of these problems. This kind of water expansion waterstop is mainly used for concrete cast in place in the construction joints or deformation joints, and concrete structure into one of the foundation projects, underground facilities, tunnels, culverts, water transfer channels, water retaining dams, etc., water expansion waterstop can extend the service life of engineering and construction.
The role of water-expandable waterstop.
Water expansion waterstop is the use of high elasticity of rubber, water expansion waterstop in a variety of loads to produce elastic deformation, so as to play a solid seal, to prevent leakage of building structures, water seepage and play a shock-absorbing buffer, in many engineering and architectural design, civil construction, water and soil structure between a certain expansion requirements, and the existence of waterproof earthquake, etc., so the use and installation of water expansion type waterstop is the sister also above All kinds of problems of the means.
The main uses of water-expanding waterstop.
In many engineering design, there are certain expansion and contraction requirements between civil engineering and soil structure, and there are problems such as waterproofing and earthquake prevention, so the use and installation of rubber water stops is a means to solve the above problems, water expansion type water stops to be used for concrete cast in place in the construction joints and deformation joints, and concrete structures become one of the foundation projects, underground facilities, underground facilities, tunnels and culverts, water transfer channels, water retaining dams etc. Ensure the service life of the project construction.
