Rubber Water stop Application Scope & Standards
Rubber water stop with water swelling rubber water can be applied to underground
structures like dams, reservoirs, swimming pools, roofing and other building materials
and structures used in the deformation joint waterproof. Because concrete structure
has become one of the basic part of the engineering, underground facilities, tunnels,

Nancy Ph: (86)15731809416 Tel/Fax: (86)318 5227227
culverts, water aqueducts, dams, that is mainly used for concrete cast in the
construction joints for ensuring life of the project construction. So it is very important
in construction.
Water-stop complies with GB18173.2-2000 standard for polymer waterproof aterial -
water stop production. According to users' piratical requirements in different projects,
different parts, different slopes, our products can be equipped with cross. What's more,

Sealing material of choice in accordance with provisions:
Structures should be based on the level of importance, the amount of deformation and
pressure, so that the water-stop can be used properly.
Under normal circumstances, we generally advise you to choose the natural rubber
water-stop.
When it comes to weak acid and alkali corrosive media, you should use neoprene
rubber water-stop.
When it comes to oil medium, you should use nitrile rubber water-stop.
When the application might be eroded by mold, water stop mildew should be
considered. At this time, the water-stop choos should reaches level 2 and more.
According to the piratical using temperature.
When it comes to waterproof sheet materials such aswelding, you should use its sam le
synthetic resin type water stop (EVA, PE, ECB, HDPE, PVC).
Construction & Installation of rubber water-stop
In construction, some or all of the rubber water-stop is buried in the concrete during
➢ -25 - 60 , it is better to choose chloroprene rubber water stop.
➢ -35 - 60 , it is better to choose natural rubber water stop
➢ -40 - 60 , it is better to choose EPDM rubber water stop.

pouring process. Because there maybe are many sharp corner stones and sharp steel
heads in concrete, we need notice its installation positioning method and pouring
pressure during water-stop position and concrete-pouring process to avoid water-stop
punctured.

stop punctured. So in order to keep effective of waterproof function, specific matters
tips in construction as follows:
Rubber water-stop can't resist long time outdoor exposure, should prevent from the
rain, do not contact with strong polluting chemicals. It's better to keep products in
stored places where temperature changes from - 10℃ to + 30℃, and relative humidity
from 40% to 80%.
During transportation & construction, you should
prevent the products from damage of the machinery or
steel bar. The storage and transportation of finished
products should be taken in the flat circumstance, don't increase the pressure.
In construction process, the product must be installed properly, avoid the displacement
during concreting and guarantee the water stop in the correct position in concrete.
In construction process, the product must be fixed installation, avoid the displacement
during concreting and guarantee the water stop in the correct position in concrete.
Construction/Inducing joint
Expansion/Settlement joint

Nancy Ph: (86)15731809416 Tel/Fax: (86)318 5227227
The common methods of fixing water-stop: using the additional reinforcement fixing,
special fixture fixing, lead wire and fixed
templates fixing, etc. If you want to punch, only
need to select edge part of the installation
area, shall not damage other parts.
When ordering the products, according to the
engineering structure, calculation length of
good product design, you should provide us drawings. Because the heterotypic
structure should have the drawings and we can check the hose connection in the whole
part. Because of the production process or transportation limitation, needing
connecting at the scene, you should adopt the method of the electric heating plate
vulcanizing bonding or cold bonding (rubber water-stop) or welding (plastic water-
stop) method. And if you still have difficulties in construction process, our company can
send technical personnel on-site guidance.
Transportation & Storage
Products during transportation and storage, avoid direct sunlight, do not contact with
heat, oil and hazardous solvents. Do not affect the quality of rubber in contact with the
substance. Finished product should be taken straight flat, do not increase the pressure.
Storage areas best kept -10℃ ~ + 30℃, relative humidity 40% - 80%, and should be
kept clean.

It is important to ensure that the center of the water stop is placed in the center of the
movement/expansion joint and
that the water stop doesn’t move in
relation to the joint while the
concrete is poured. Water stop
movement is a particular problem
when there are high concrete pressures during the concrete pour.
The concrete underneath the water stop as to be vibrated and consolidated during the
pour otherwise porosity, cavities and honey combing will occur.
When the water stop is mounted
horizontally the end should rise upward,
in order to prevent air entrapment. The
number of longitudinal ridges should be
minimized to reduce the possibility of
trapping air under water stop.
Once the water stop has the concrete
poured on one side, the other side needs
to be cleaned to ensure it is free of sharp
objects.

Package

Also, packed as per instructions from clients.
Fabrications
The integrity of the water stop system is
dependent on proper fabricated water stop
splices to achieve a complete fluid-tight system. All directional changes and
intersections shall be miter cut and spliced by TIG welding to maintain continuity of
the outside flanges and "V" expansion zone. Water stop corners and intersections
should be fabricated where strict quality control measures are maintained.
Installation
Proper water stop splicing, including butting straight lengths, changes of direction,
and intersections are extremely important. Water stop should be continuous for the
extent of the joint. Position the water stop so the "V" expansion zone is centered in the
joint. Support and secure the water stop in position to limit displacement during the

Nancy Ph: (86)15731809416 Tel/Fax: (86)318 5227227
placement of the concrete.
Important precautions:
Thoroughly consolidate the concrete around the water stop to prevent voids or
honeycombing next to the water stop. Pay
particular attention to the underside of
horizontally placed water stops. Intimate
contact of the concrete and water stop is
necessary for full performance of a water
stop. Voids next to the water stop can
significantly reduce its water stopping ability. Maintain adequate clearance between
reinforcing steel and the water stop. Typical clearance should be twice the maximum
aggregate size. Inadequate clearance can promote the formation of voids due to
aggregate bridging. It is important to maintain continuity of the entire water stop
system. Splices must be properly completed at all changes of direction, transitions,
intersections, and butt joints. Any breach in continuity can be a point of leakage.
Tips:
The plastic water stops that were in the fuel terminal joints all failed due to the high
heat of the fire.
The Health Protection Agency and the Major Incident Investigation Board provided
advice to prevent incidents such as these from happening again, including the
utilization of stainless steel water stop in place at all concrete joints to prevent fuel
from escaping the bound walls.

How does lead rubber bearing work?
Lead rubber bearing avoids deformations and damages to buildings. During the
earthquake, the un-isolated building will vibrate back and forth in varying directions
due to the inertial forces and result in deformation and damages of the building. In
contrast, the base isolated building will also displace but remains its original shapes
and avoid damages - that is because the lead rubber bearing effectively dissipates the
inertial force upon the building, extends the building’s period of vibration and decrease
the acceleration of the building.
The lead plug will slide with
laminated rubber during
earthquake but convert this
energy of movement to heat so
that it efficiently reduces the
inertial force upon the
building, which slow the
vibration of the building.
Meanwhile, the rubber part will preserve its original shape due to high elasticity.
