Joint Sealing and Waterproof Rubber Expansion Seal Strip PZ Products Rubber Strip PN Putty Type Manufacturer

Dam & Reservoir Construction: Installed in horizontal/vertical concrete joints of dam bodies, spillway gates, and reservoir shorelines. During construction, the waterstop strip is embedded into pre-reserved grooves or bonded to concrete surfaces before pouring the next concrete segment. It adapts to slight structural deformation caused by water pressure and temperature changes, preventing leakage at joint gaps.

Sluice & Aqueduct Installation: Applied to the connection between sluice gate frames and concrete piers, as well as aqueduct flange joints. It is fixed with stainless steel clips to avoid displacement during concrete pouring, ensuring tight sealing against water seepage in water conveyance channels.

Basement & Subway Tunnels: Used in construction joints (e.g., wall-floor joints, horizontal construction seams) of basements, and segment joints of subway tunnels. Before concrete placement, the strip is bonded to the finished concrete surface with special adhesive, then pressed firmly when the next concrete layer is poured. It effectively blocks groundwater infiltration in high-humidity underground environments.

Underground Pipe Galleries: Installed in longitudinal/circular joints of pipe gallery walls and floor slabs. During assembly, it is placed between precast concrete segments, relying on its post-swelling property to fill micro-gaps caused by segment installation errors, ensuring long-term waterproofing for utility pipelines (water, gas, electricity) inside.

Sewage & Water Treatment Plants: Deployed in concrete joints of sedimentation tanks, aeration tanks, and sewage pipelines. The non-toxic, low-VOC waterstop strip is bonded to tank walls or pipe interfaces before concrete curing, resisting corrosion from sewage and wastewater, and preventing leakage that may pollute soil or groundwater.

Bridge & Viaduct Construction: Applied to the joints of bridge piers, bearing platforms, and box girders. It is embedded in the concrete formwork before pouring, adapting to the slight settlement of bridge structures and sealing gaps to avoid rainwater seepage that could damage steel reinforcements inside.

Chemical Plant Tanks & Pools: Used in joints of chemical storage tanks (e.g., acid-base tanks) and circulating water pools. The strip is fixed with pressure-sensitive adhesive on tank foundations or pool walls, withstanding chemical erosion and high-temperature changes, and preventing hazardous chemical leakage.

Power Plant Cooling Towers: Installed in concrete joints of cooling tower linings and water distribution pipelines. During construction, it is placed in expansion joints to compensate for thermal expansion/contraction of the tower structure, ensuring no cooling water seepage that affects power generation efficiency.
