Rubber waterstop belts are widely used in construction engineering for their excellent waterproofing

Application Scenario: Construction joints and settlement joints of basement floors and side walls to prevent groundwater seepage.

Characteristics: Adopt CB-type embedded rubber waterstop belts, embedded in concrete. The middle hole adapts to structural settlement deformation to avoid leakage through cracks.

Case: Post-cast strips in basements of high-rise buildings and underground garages.

Application Scenario: Circumferential/longitudinal joints of metro tunnels and highway culverts, addressing uneven foundation settlement or temperature deformation.

Characteristics: Mostly use EPDM rubber waterstop belts (with strong weather resistance), combined with steel-edged rubber waterstop belts to enhance water pressure resistance (e.g., river-crossing tunnels with high water pressure).

Application Scenario: Transverse and longitudinal joints of concrete dams, as well as joints of spillways and canals.

Characteristics: Use natural rubber waterstop belts (resistant to fresh water corrosion) or neoprene waterstop belts (resistant to sewage, acids, and alkalis) to prevent reservoir water leakage.

Application Scenario: Interfaces of irrigation canals and urban drainage pipes to prevent water from seeping into the soil or structure.

Characteristics: Employ flat-type waterstop belts or back-sticking (EB-type) waterstop belts, installed on the outer side of the structure for easy maintenance.

Application Scenario: Joints between bridge decks to accommodate thermal expansion, contraction, and dynamic deformation (e.g., from vehicle loads).

Characteristics: Use steel-edged rubber waterstop belts or water-swellable rubber waterstop belts (which expand upon contact with water to fill gaps), combined with concrete to prevent rainwater infiltration.

Application Scenario: Connections between bridge abutments and subgrades to prevent water from eroding the foundation.

Characteristics: Adopt CP-type embedded waterstop belts (without middle holes) for high waterproofing requirements in settlement joints.

Application Scenario: Joints of subway station structures, underground pipe galleries, and utility tunnels to resist groundwater and rainwater.

Characteristics: Combine EPDM waterstop belts (for long-term outdoor durability) with water-swellable rubber strips for enhanced sealing.

Application Scenario: Joints of sewage tanks, sedimentation tanks, and pipelines, requiring resistance to corrosive media.

Characteristics: Use neoprene waterstop belts (acid/alkali-resistant) or fluororubber waterstop belts (for extreme corrosion resistance in special projects).

Application Scenario: Seismic joints and waterproof nodes of nuclear containment structures, requiring high safety and durability.

Characteristics: Employ high-quality EPDM waterstop belts with strict temperature resistance (-40°C to 60°C) and radiation resistance.

Application Scenario: Offshore platforms, underwater tunnels, or port foundations exposed to seawater.

Characteristics: Use corrosion-resistant EPDM waterstop belts or stainless steel-edged rubber waterstop belts to withstand seawater erosion and high water pressure.

Material Selection: Match the waterstop belt material (natural rubber, neoprene, EPDM, etc.) to the environment (fresh water, seawater, chemicals, temperature).

Installation Method: Choose embedded, back-sticking, or steel-edged types based on structural stress and deformation requirements.

Joint Type: Differentiate between construction joints, settlement joints, and expansion joints to select appropriate models (e.g., CB-type for deformation resistance, EP-type for simple waterproofing).
