PENEBAR SW-55™

Controlled Expansion Waterstop

Contact Us

DESCRIPTION

Penebar SW-55 is a hydrophillic waterstop that will expand in a controlled fashion when exposed to water. It is a sophisticated water-sealing product that encapsulates hydrophilic materials into a rubber base to create a built in delay system.

 

What is controlled expansion?

Controlled expansion allows Penebar SW-55 to avoid some of the problems that have been associated with traditional water-stops on many building sites:

  • It does not expand prematurely and does not absorb any water from fresh concrete poured against it.
  • It will not expand to a point where the hydration process causes it to disintegrate and hence will not be washed away when subjected to a constant water flow.
  • It will not cause excessive internal pressure in the concrete.

Advantages

  • Concrete is allowed to gain full strength before expansion.
  • Built-in delay system prevents premature expansion.
  • Can be bedded into wet concrete.
  • Does not disintegrate over time.
  • Not affected by repeated wet and dry cycles.
  • Easy to apply to rough concrete surfaces.
  • Can be used in horizontal and vertical joints.
  • No problems with compaction or displacement.
  • Easy to install.
  • Nontoxic and does not require any special handling.

Typical projects

Penebar SW-55 can be applied to no-moving, cold joints on all concrete building projects that need protection from moisture ingress, including:

  • Underground structures.
  • Basements.
  • Precast panels.
  • Tunnels.
  • New concrete onto old concrete.
  • Manholes.
  • Retaining walls.
  • Storage tanks.
  • Concrete pipe.
  • Car parks, etc.
