Sikaswell S-2 Waterstop

Description SikaSwell S-2 is a specially formulated, high-performance,
swellable, one-component, polyurethane-based waterstop
for use in all kinds of construction joints. Swelling rubber
creates a compression seal within joint, blocking the
passage of water.
Where to Use n Designed for construction joints in new watertight concrete structures.
n Excellent for sealing pipe penetrations through walls and
floor slabs.
n Excellent for sealing joints between precast elements.
n May be applied to horizontal, vertical and overhead surfaces.
n Ideal for watertight construction joints between new and
existing concrete.
Advantages n Swells up to 100% in potable water, slightly less in salt
water and wastewater.
n Permanently water resistant, with no leaching and does not dissolve in water.
n Capable of sealing construction joints with head pressures of up to 50 psi (115 ft. head).
n Elastic-withstands wet/dry cycling.
n Easy, simple application.
n Adaptable in the field to suit job requirements.
n No nails, glue, or hooks required.
n Controlled expansion eliminates cracking in fresh concrete.
n Offers resistance to various chemicals.
n Thixotropic properties allow SikaSwell S-2 to seal irregular joint surfaces.
n Very economical.
n Saves labor by eliminating inverted keyways, split forming, heat splicing, special fittings
and tieing to rebar associated with conventional PVC waterstops.
n No mixing required.
n Allows more thorough vibration of concrete at joint, resulting in better concrete consolidation which aids in achieving a watertight joint
