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.
 Foundations and basements.
 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
