SikaSwell S-2

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

Designed for construction joints in new watertight concrete structures.
Excellent for sealing pipe penetrations through walls and
floor slabs.
Excellent for sealing joints between precast elements.
May be applied to horizontal, vertical and overhead surfaces.
Ideal for watertight construction joints between new and

existing concrete.

Advantages

Swells up to 100% in potable water, slightly less in salt
water and wastewater.
Permanently water resistant, with no leaching and does not dissolve in water.
Capable of sealing construction joints with head pressures of up to 50 psi (115 ft. head).
Elastic-withstands wet/dry cycling.
Easy, simple application.
Adaptable in the field to suit job requirements.
No nails, glue, or hooks required.
Controlled expansion eliminates cracking in fresh concrete.
Offers resistance to various chemicals.
Thixotropic properties allow SikaSwell S-2 to seal irregular joint surfaces.
Very economical.
Saves labor by eliminating inverted keyways, split forming, heat splicing, special fittings
and tieing to rebar associated with conventional PVC waterstops.
No mixing required.
Allows more thorough vibration of concrete at joint, resulting in better concrete consolidation which aids in achieving a watertight joint.
