StarTie

Wall tie for securing a new leaf to an existing wall

StarTies are quick and easy to install and engineered from austenitic stainless steel Grade 316 as standard. StarTies conform to Australasian standard AS/NZS2699 and cover durability classifications R2, R3 and R4.

System Components

  • StarTies
  • Hand-held support tool
  • Insulation retention clips
  • Drill bit for pilot hole (hard masonry)

The tie is installed into the existing masonry and simply bedded into the mortar as the new wall is constructed.

 

1. Drill 5mm pilot hole into existing wall (not required with low density blocks)

2. Load tie into hand held or power support tool and line up with pilot hole while resting support tool on new leaf

3. Drive in tie with hammer or SDS drill. (If insulation is installed, fit retaining clip over the StarTie)

4. If required, bend the exposed end of the StarTie down using the support tool so that it lies parallel to the new mortar bed

5. Embed the outer end of the StarTie into the mortar as the new leaf is constructed

5. Embed the outer end of the StarTie into the mortar as the new leaf is constructed

Health and Safety

Helifix tie and reinforcement installation procedures often require the use of power tools to cut or drill holes into or through masonry-type substrates. Depending on the system used, installation may also involve the use of cementitious or epoxy-based bonding agents. Accordingly, installers may face any one or combination of work site hazards.
Electricity, gas and water pose immediate and dangerous hazards and it is essential that appropriate measures are taken to locate, identify and isolate any such service which may be present in the wall under repair prior to cutting, drilling or installing ties.
Similarly, all necessary safety precautions must be taken while cutting, drilling, installing ties or using chemicals. Appropriate safety clothing, footwear, eyewear and hearing protectors should always be worn. Only well-insulated, quality tools should be used.

  • New build cavity and veneer wall construction
  • Connecting a new masonry leaf to an existing wall or frame
  • Securing a new wall, wall extension or section to an existing wall
  • Stainless steel, self-tapping, one piece tie
  • Multiple drip points prevent cross cavity water transfer
  • Excellent stress free mechanical connection and mortar bond
  • Can be installed through insulation without significantly adversely affecting its thermal performance
