Waterstop Neoprene Rubber Waterstop For Building Waterproofing

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.

Water swelling strip

Standard specifications, complete models, strong water stop, integrated molding, tear resistance

Features

1、Immersion expansion, "water to stop water";

2、Slow expansion rate, the expansion rate of 186h of water immersion ≤ 50% of the maximum expansion rate;

3、Construction is convenient, low price

4、Non-toxic and non-polluting

5、No dissolved material precipitation under the action of long time water immersion;

6、Compared with other hydrophilic expansion waterstop, the biggest difference is that its hydrophilic expansion by long-term repeated expansion is still not lost.

Construction process

(1) to have a reserved type of paste, in the cast-in-place concrete need to be reserved on the waterstop placement slot (can be nailed in the formwork reserved wooden strips).

(2) After removing the cast-in-place concrete formwork, remove the surface so that the joint surface is water-free, clean and free of debris.

(3) embed the waterstop into the reserved slot. If not reserved slot, the vertical joints can be added with binder full-length

paste, or cement nails with wooden strips to fix the waterstop; the horizontal joints can be directly pasted on the concrete surface.

(4)The water-stopping strip should be pasted as soon as possible after pouring concrete.

(5) in the process of installation and paste, should prevent the water-stop strip from being contaminated and the role of water, so as not to affect the use of the effect.
