PC-Swellbar® 100

Hydrophilic swellable joint sealing bar

PC-Swellbar® 100 is a new generation high-performance self-adhesive acrylic polymer-based expanding tape. It expands up to 400% when in contact with water. In a totally dry state, PC-Swellbar® 100 will shrink to its original installation dimension and re-expand on wetting. PC-Swellbar® 100 is used in concrete construction for the sealing of construction joints including wall-to-base connections, pipe entry systems, sealing of openings and interface sections between existing and new concrete.PC-Swellbar® 100 is capable of sealing heads of water up to 65 metres (7.0 Bar) in ground and saltwater environments. PC-Swellbar® 100 is ideal to be used in horizontal and vertical construction joints for cast in-situ concrete structures and pre-cast elements.

PC-Swellbar® 100 complies to NSF/ANSI Standard 61 Drinking Water System Components – Health Effects, ensuring PC-Swellbar® 100 is safe for use in drinking water applications. Therefore, it is suitable to use in various potable water retaining structures like water tanks, swimming pools and reservoirs.

AREAS OF APPLICATION

Uses all types of construction joints, pipe and steel work penetrations through walls and floor slabs, around all types of penetrations and connection joints, and construction joints in cable ducts.

Water Retaining Structures:
Water tanks, Reservoirs, Dams, Spillways, Sewage treatment plants, Water treatment plants, Swimming pools, Box culverts Bund walls.

Water Excluding Structures:
Basements, Underground, structures, Tunnels, Subways, Retaining walls, Pits Manholes.

Others :
New to old concrete, Poured in-situ construction joints, Roof slabs, Suspended slabs,Above & below-grade precast panels.

IMPORTANT CONSIDERATIONS

Due to expansive forces, PC-Swellbar® 100 should be both detailed and installed with a minimum 50mm clear cover to the face of the concrete. The expansion rate can vary in salt and contaminated water. Increase cover when using lightweight, low-strength concrete. Not for use where excessive shrinkage of the concrete may occur at the joint faces. Do not stretch the PC-Swellbar® 100 during installation. Not for use in movement (expansion, isolation and contraction) joints.

ADVANTAGES

  • Exceptional sealing capabilities that resist high hydrostatic head pressures, make it ideal for both potable and saltwater environments.
  • Creates a permanent and flexible gasket, providing a compression seal inside the concrete.
  • Made of high-quality, non-biodegradable chloroprene hydrophilic rubber, ensuring long-term durability and integrity of the joint and structure.
  • Can expand up to 400% in water.
  • Has undergone rigorous testing and can withstand hydrostatic head pressures of over 65 meters (7.0 Bar).
  • Suitable for use in various applications, with a particular emphasis on water-retaining structures that experience direct water pressure against the concrete joint.
  • Can be applied directly on smooth and rough surfaces with the recommended adhesive.
  • Unaffected by repeated wet and dry cycles, ensuring long-lasting performance.
  • Non-toxic, requires no special handling, and can be used in potable water structures.
  • Easy and fast to install.
  • Suitable for use in both horizontal and vertical construction joints.
  • No on-site welding is necessary.
  • NSF certified for use in potable water applications.
