High Quality Back Stick Type Rubber Waterstop with Reasonable Price

In order to ensure that the embedded rubber water stop belt position is correct, the specific practices performed in accordance with the following requirements:
1, in the rubber sealing belt on both sides from the edge of 40mm drilling, diameter 10mm, pitch 1000mm.
2, with 10 additional distribution in welding steel bar, position with the rubber sealing belt has opened a hole, so that the rubber sealing belt just can be set on the phi 10 steel, in the embedded rubber water stop belt with water swellable rubber sealing pad trap on phi 10 steel. Must ensure that the rubber sealing belt position accurate construction.
3, in the rubber sealing strip is exposed is Phi 10 Phi 12 steel reinforced two-way welded connection, the rubber strip is embedded in the steel mesh, ensure the correct position in the embedded rubber water stop belt, the formation of effective waterproof.
The above work is completed, an embedded rubber water stop belt in the upper (125mm), the lower floor of reinforced steel wire mesh closed mouth is added before lashing bottom reinforcement.

Note:
1. Mixed rubber and metal is only suitable for waterstop with steel edge.
2. If there are other requirements, inspection items can be appropriately added according to buyer and seller. If evaluating mould test in line with users, its anti-mold property should be equal to or above Grade 2.

Sealing mechanism
In the embedded rubber water stop belt is characterized by high elastic properties under various loads will produce elastic deformation will occur the volume expansion of the water, so it can play a strong role in sealing, which can prevent the water into the building interior and exterior of the building to prevent the building of water to the outside world, also can play a damping strip the buffer.
After pretreatment of galvanized steel inserted into the middle rubber vulcanization forming, strong bonding force between the two, has obvious effect of seepage. In buried steel edged waterstop in the middle rubber body structure deformation by compression, stretching, deformation, and the sealing effect of water; galvanized steel and concrete good adhesion, not easy to fall off and loose, the embedded rubber water stop belt can bear large pulling force and torsion. In the construction, due to the huge vibration force of concrete pouring and not easy to be fixed, will make ordinary rubber sealing belt production shift, pull off, torsion and loose and fall off, that will in the case of large water productionThe leaking phenomenon, rubber watertight strip, due to steel and concrete, not between the steel belt and the rubber to have a new permeability.
