Sealants - Tape Systems
Product                                                         Description
Sikadur-Combiflex joint sealing consists of two products:
  • Sikadur-31 Adhesive (Normal, Long Potlife or Rapid)
  • Combiflex (SikaNorm Hypalon)
Sikadur-31 Adhesive is epoxy resin based and establishes a strong bond to the substrate and the Combiflex. SikaNorm Hypalon is highly elastic, rot proof and chemically and UV resistant sheet membrane with a thickness of 1mm or 2mm.

Sikadur-Combiflex can be applied on dry or damp substrates. It shows remarkable adhesion to concrete, iron and steel and is perfect for joints with very large expansion. Sikadur is also weather and waterproof. The Sikadur-Combiflex system is approved for potable water contact.

Uses
  • Sealing internal joints in new or refurbished concrete water tanks, reservoirs, pipelines, sewers and swimming pools
  • Joints in bunds and tanks for heating oil and fuel oil, etc.
  • Sealing underwater joints in Insitu
  • Sealing joints in large decks of multi-storey car parks
  • Sealing joints in tunnel, silos and roofs
  • Sealing and repairing joints that have more movement than can be accommodated by conventional elastomeric wet applied sealants
Advantages
  • Applicable on dry and damp surfaces
  • Quick hardening in low temperatures
  • Three adhesive types for quick application between 50C and 450C
  • For large expansion joints or cracks
  • Of permanent elasticity even at low temperatures
  • Weather resistant
  • Water resistant
  • Approved for use in potable water (AS4020:2005)
  • Rot resistant
  • Resistance against many chemicals
  • Excellent adhesion to most conventional building materials
  • Perforations along edges of Combiflex provide “rivet effect” and adds mechanical fixing to augment chemical bond
  • No need to remove failed sealant from old joints before use
Masterflex 3000 joint sealing system consists of two products - Masterflex 3000 tape and Concresive 1446 epoxy. The Masterflex 3000 tape is a highly elastic, rotproof and chemically resistant sealing tape. Concresive 1446 is a two part epoxy compound which establishes a strong bond to various types of substrate.

Uses

Sealing of construction joints, expansion joints, connecting joints, cracks and crevices to ensure a longterm waterproof and functional building envelope. Typical uses are for concrete tanks, cast and cement-pipe connections, bridge decks, tunnels, water towers and reservoirs, ponds, silos, containers, secondary tanks. Masterflex 3000 can be applied on dry or slightly humid substrates. It is ideal for joints with very large expansion or irregular, broken joint flanks. Masterflex 3000 is grey coloured, weather and waterproof.

Advantages

  • Durable
  • Long lasting elasticity, even at low temperatures
  • Root resistant
  • Cost effective
  • Approved for use with potable water
  • Easy to apply
  • User friendly heat welding tape overlaps
  • Can be applied horizontally, vertically and even overhead
Emer-Band is a Hypalon rubber membrane which is designed to be bonded over movement joints or cracks in a structure to prevent the ingress of water and chemicals. It is bonded in position with Nitomortar AP, a two-part epoxy adhesive specifically formulated for the purpose.

Emer-Band may be used to seal joints in car park decks, podiums, balconies, walkways and other elevated structures, where the Emer-Band can be protected from mechanical damage by a cover plate. It can also be used for over-strapping joints in basements, subways, tunnels, refineries and substructures in general.

Emer-Band can also be used on silos, roofs as well as water immersed applications such as tanks, sewers, reservoirs, pipelines and swimming pools where the joint movement may exceed the capability of conventional gun applied elastomeric sealants.

Advantages

  • Forms a tough, flexible joint flashing
  • Accommodates continuous, and pronounced cyclic movement
  • Range of sizes available to suit most applications
  • Excellent resistance to UV and weathering
  • AS4020 approved for potable water
  • Application to dry and damp surfaces
  • Excellent adhesion to most construction materials
  • Performance not affected by climatic extremes
  • Rot resistant
  • Emer-Band can be heat welded for the continuity of long joint lengths
  • Perforations along the edges of the Emer-Band provide a mechanical fixing element in addition to the excellent chemical bond offered by the Nitomortar AP
  • Resistant to a wide range of chemicals
