Penebar SW-55™ is a concrete joint water-stop that will expand in a controlled fashion when exposed to water. A sophisticated water-sealing product that encapsulates hydrophilic materials into a rubber base to create a built-in delay system.
Penebar SW-55 is a concrete joint water-stop that will expand in a controlled fashion when exposed to water. 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.
