About Product:

Lokfix mix and place grouts are used for high strength corrosion resistant anchoring of bolts and bars from 12-51 mm diameter into concrete, rock, masonry, or brickwork where high speed of installation and early application of load is required. Permanent installation of reinforcement starter bars, foundation bolts, base plates, balustrading, barriers and safety fences, railway tracks, tie-back anchors, reinforcement dowelling abutments, ground anchors for towers, cranes, dock sills, etc.

Advantages

• Rapid strength gain
• Vibration resistant
• Corrosion-resistant
• Non-expansive
• Can be placed underwater.

Description

Lokfix is produced in two versions. The two versions of Lokfix are all pre-measured, two-part, filled polyester resin grouts. After hardening, the grout produces anchorages of consistent reproducible values. The versions are:

Lokfix S - used where the hole diameter is less than 25 mm greater than the bar diameter.

Application instructions

1. Hole preparation and formation

• The optimum performance of Lokfix grouts requires rough-sided, dust-free holes. Use of rotary percussive drills with air or water flushing is recommended.
• Diamond drilled holes should be under-reamed.
• Cast holes should preferably be inverse dovetail configuration. If parallel-sided holes are cast they should be rough to provide adequate keying.

2. Bar preparation

All bars should preferably be degreased and all flaky rust removed.

3. Mixing

• A complete pack of resin and catalysed filler should be mixed in one operation. Mixing may be carried out manually or mechanically. When a smooth, even consistency is achieved the grout is ready for use and should be placed well within the gel time of the grout (see properties).
• Packs have been designed to produce practical and economic volumes of grout. Do not attempt to mix partial pack components.

4. Placing

Lokfix S  The mixed grout should be poured steadily into the prepared holes. The anchor bar is then pressed into the hole to the required depth. Slight agitation of the bar will assist in achieving a complete bond. The bar should then be left undisturbed in the required position until the resin is set.

Limitations

1. At permanent operating temperatures above 40oC, creep of the cured grout may become significant.
2. Resin anchors should not be used where structural load bearing performances have to be maintained in anchors subjected to fire conditions.
3.  For use at temperature below 5oC, seek advice from Fosroc.

Precautions

Health and safety

Lokfix and Fosroc Solvent 105 are flammable. Confined areas must be well ventilated and no naked flamed allowed. Do not smoke during use. Contact with the skin should be avoided as certain sensitive skins may be affected by contact with the polyester resin. In such cases if contact with the resin occurs, the skin should be washed immediately with soap and water - not solvent. Gloves and barrier creams should be used when handling these products. Eye contamination must be immediately washed with plenty of water and medical treatment sought.
