Tri-Bar
Why Tri-bar? Tri-bars are three finned helical Stainless Steel reinforcement rods, which can be used in accordance with (BS 5628 part 2) for reinforcing bed-joints to enhance lateral loading resistance in new and existing buildings. Tri-bars can also be used to repair many structural defects in existing masonry by using our repair strategies like over-pinning with ring beams, general crack stitching repairs and lintel failures.
Benefits & Features:
- Quick installation.
- Low labour Costs.
- Easily installed in bed joints.
- Minor visual and structual disturbance.
- Enhances lateral loading resistance .
- Lengths up to 7 metres.
- Austenitic 304 or 316 stainless steel.
- Bonded with Tri-Set resin or cemspand grout.
- Effective in cavity and solid walls.
- Tensile strength more than double required by BS 5628.
- Good bonding to resins and grouts.

TRISET PRODUCT DATA SHEET
DESCRIPTION
Triset is a rapid curing 'one shot' two part chemical anchoring cartridge system based on a polyester resin. Applied in one single action to produce a cost effective, tough, chemical resistant fixing. Triset is ideal for close-to edge applications (unlike expansion anchors) as no stress is placed on the surrounding substrate. Versatile in use, Triset is suitable for fixing wall ties, starter bars, studs, bolts or large screws in a wide range of substrates including brickwork, concrete, masonry, stone and PFA blocks. Hollow base materials can be securely fastened into by using Triset in conjunction with a sleeve or sieve.
PREPARATION
1. Drill hole to the correct diameter and depth (see chart for guide), ideally using a rotary percussion machine. For optimum results the hole must be coarse sided. If the holes are produced by diamond drilling the surfaces should be thoroughly roughened.
2. Remove all dust and debris from the hole using a hand air pump or a stiff rotary brush.
3. All bars should be clean and free from oil or grease and all flaking rust should be removed. Threaded rod or struts should be chisel-ended to prevent them being unscrewed from the cured resin.
APPLICATION
1. Attach the mixing nozzle to the cartridge (screw down hand tight).
2. Mount the cartridge into the dispensing gun.
3. Squeeze out material through the nozzle until an even colour is achieved (approximately 5-6 inches of extruded material should be adequate).
4. Apply to the hole working from the base out. Once the required fill is obtained release the pressure and wipe away excess material. Place the bolt or screw into the hole with a rotary action. Wipe away excess material. Attach fixture once resin has cured.
NB Once material has started to extrude through the nozzle over pressuring the system will not increase flow rate. And can cause leakage from the rear of the cartridge.

Tension figures quoted are tested in accordance with BS5080 part 1 in 63 N/mm sq concrete blocks (12 x 12 x 12 inches). In all cases for 16mm and 20mm anchors failure of the concrete block was observed before the anchor was dislodged.
The ultimate pull out strength is varied by:
1. The strength of both the substrate and bar/stud
2. The length of the resin bond to bar
3. Hole preparation
4. Anchor separation
Safety factors of between 2:1 and 4:1 should be considered depending on the strength and nature of the substrate. Due to the inconsistent nature of hollow blocks and bricks tension figures may vary. Site testing should be carried out where necessary to establish particular suitability. In order to achieve maximum performance the distance between the centres of the anchors should be a minimum of2.5 x the embedment depth, and 1.25 x the embedment depth for the minimum distance from edges.
STORAGE
Store in a dry area between 5 C and 25 C. Do not expose to direct sunlight. Storage at higher temperatures will reduce the shelf life.
