FOSROC LOKFIX S is a high-performance, pre-packaged polyester resin anchoring grout designed for fast, secure, and durable fixing of bolts, bars, and threaded anchors into concrete, masonry, brickwork, and stone. Engineered by Fosroc, a global leader in construction chemicals, Lokfix S delivers exceptional bonding strength, rapid curing, and reliable load transfer, making it an ideal solution for both structural and non-structural anchoring applications.

Lokfix S is supplied as a two-component cartridge system that mixes automatically during extrusion, ensuring accurate proportioning and consistent performance on site. Its solvent-free formulation provides safe handling, minimal shrinkage, and excellent long-term durability in a wide range of construction environments.

Product Characteristics

FOSROC LOKFIX S is formulated to provide strong mechanical anchorage through chemical bonding rather than expansion pressure. This makes it particularly suitable for close-edge fixings and situations where traditional expansion anchors may cause cracking or damage to the substrate.

Key characteristics include:

Rapid setting and early strength development

High bond strength to concrete and masonry

Non-shrink, solvent-free formulation

Easy extrusion using standard applicator guns

Suitable for dry and damp holes

Minimal stress on base material

Its thixotropic consistency allows it to stay in place without sagging, even in vertical or overhead applications.

Performance Advantages

One of the main advantages of Lokfix S is its fast curing time, which significantly reduces installation downtime. Anchors can often be loaded within a short period, improving project efficiency and productivity.

Other performance benefits include:

High load capacity, ensuring reliable anchorage

Uniform stress distribution, preventing concrete cracking

Excellent vibration resistance, ideal for machinery fixings

Strong adhesion to irregular or rough hole surfaces

Durable bond resistant to moisture and environmental exposure

Unlike expansion anchors, Lokfix S does not induce radial stress, making it safe for use in thin concrete sections and near edges.

Typical Applications

FOSROC LOKFIX S is widely used in commercial, industrial, and infrastructure projects for a variety of anchoring applications, including:

Structural Fixings

Starter bars and reinforcement dowels

Structural steel connections

Handrails and balustrades

Mechanical & Electrical Installations

Heavy machinery base plates

Cable trays and pipe supports

HVAC and electrical equipment

Construction & Renovation

Retrofitting anchors into existing concrete

Fixing façade elements and signage

Door and window frame anchoring

Infrastructure & Civil Works

Bridge parapets and crash barriers

Street furniture and lighting poles

Railings, guardrails, and safety barriers

Its versatility makes Lokfix S suitable for both new construction and rehabilitation projects.

Ease of Application

Lokfix S is designed for simple and efficient on-site use. Installation involves drilling a hole, cleaning it thoroughly, and injecting the resin before inserting the anchor. The cartridge system ensures proper mixing, eliminating the risk of incorrect ratios.

Key application benefits include:

No mixing equipment required

Reduced material waste

Clean and controlled dispensing

Consistent quality in every application

The resin adapts well to different hole diameters and depths, making it suitable for a wide range of anchor sizes.

Durability & Reliability

FOSROC LOKFIX S offers long-term performance even in challenging environments. Once cured, it provides excellent resistance to:

Moisture and humidity

Mild chemical exposure

Vibrations and dynamic loads

Temperature variations

This ensures that anchors remain secure and reliable throughout the service life of the structure.

Quality Assurance

Manufactured under strict quality control standards, FOSROC LOKFIX S is produced to ensure consistent performance and compliance with international construction requirements. Fosroc’s global expertise and technical support further enhance confidence in product reliability and site performance.

Packaging & Storage

Lokfix S is supplied in sealed cartridges that ensure extended shelf life when stored in cool, dry conditions away from direct sunlight. Proper storage maintains resin reactivity and application consistency.

Conclusion

FOSROC LOKFIX S is a fast-setting, high-strength polyester resin anchoring solution designed to deliver dependable performance in a wide range of construction and engineering applications. Its ease of use, strong bonding capability, rapid curing, and long-term durability make it an excellent choice for anchoring bolts, bars, and fixtures in concrete and masonry. Whether for structural reinforcement, mechanical installations, or retrofit works, Lokfix S provides a safe, efficient, and cost-effective anchoring solution trusted by professionals worldwide.
