Company: Hengshui Jianfeng Engineering Rubber co., LTD. Rubber waterstop stips are classified into 3 types, including PZ strip waterstop, Butyl Rubber Waterstop, Bentonite strip waterstop.



1 - PZ strip waterstop - Smaller Size & Stronger Structure

PZ waterstop is a new type hydrophilic watertight product manufactured of

quality vulcanized rubber and other additives, which make it expansible with

physical properties of rubber.

Applications

Pipe penetration.

Water reservoirs.

Settling pond.

Deformation and concrete construction joints of civil engineering.

Water conservancy and hydropower projects, etc.

2 - Butyl Rubber Waterstop for Concrete Constructions

Butyl rubber waterstop is a type of hydrophilic water sealing product to prevent

any passage of water through non-moving construction joints.

Composed of

quality butyl rubber and mastic or expansible clay, when exposed to water, the

waterstop swells and forms a permanent compression seal in non-moving

concrete construction joints.

Applications

Concrete construction joints.

Non-moving joints.

Portable water tank, box culverts and tunnels.

Water containments.

Pipe penetrations.

Manholes.

Slab and walls below grade.

Cast in place applications.

Utility and burial vaults.

Precast concrete wall panel system.

Wet wells.

3 - Bentonite strip waterstop -Solutions to Water Containment Needs

Bentonite waterstop is a kind of hydrophilic water sealing product coming with

incomparable durability and higher water absorption no less than 300%.

Unlike

traditional clay based waterstops, this one utilizes rubber as base material to for

a controlled, moisture active sealant - that means the bentonite waterstop will

not expand to point losing much of integrity even being washed away by water

during continually expansion.

Applications

Joints with limited movements.

Construction joints and sheet pile joints.

Water containment and reservoirs.

Water and sewage treatment.

Primary and secondary structures.

Manholes and elevator pits, manure pits

Tunnels, culverts, dams, water tanks and canals.

Pipe penetrations.

Swimming pools and parking garages.

Retaining walls.

Precast concrete structure.

Foundations and basements.

Slabs and king post.

Fast track projects
