MOTOR-DRIVEN GAS COMPRESSOR PACKAGE
Chockfast Red HF is the next generation, three-component, 100% solids epoxy grout. Our latest product in a long line of successful machinery grouting and chocking compounds, Chockfast Red HF offers excellent high-flow qualities for improved working and placement – and it is pumpable.
Chockfast Red HF is suitable for small and large volume pours – achieving excellent cured properties for dependable, long-term service under increasingly difficult-to-grout industrial machinery and equipment.
The contractor achieved highly successful results using Chockfast Red HF – installing the grout under a gas compressor with an elevated foundation. This installation had great significance for the contractor – while it was their first installation using a pump placement method, it was also their first installation using epoxy grout.
The contractor completed installation of Chockfast Red HF using pumped placement technique. The pump used was a Model P-25 grout pump, manufactured by Machine Technologies. 40 units, or 100 cu. ft. (2.83 m³, 2,832 liter), of Chockfast Red HF was required to complete the job.
DIFFERENT FACTORS WERE TAKEN INTO CONSIDERATION ON THE DECISION TO USE CHOCKFAST RED HF AND THE PUMPED INSTALLATION METHOD
Application complexity The fabricated skid had a substantial size “footprint” – large overall dimensions that can make preparations and installation of grout more difficult and costly. In addition, the equipment package was located on a 3 ft (914mm) elevated foundation. The additional time needed and cost involved with setting up the work area (platforms, head troughs, equipment needs, etc.) became a key consideration to the final selection of Chockfast Red HF, and the pump placement method.
Remote location Nobody need imagine the ramifications of being unprepared for the grout work in a remote location.
WITH THIS SUCCESSFUL GROUT INSTALLATION, SIGNIFICANT GOALS WERE ACHIEVED
• Long working time, but fast curing rates.
• High cured structural properties – compressive, tensile, flexural.
• High Effective Bearing Area (EBA) – greater contact for better load spread and vibration damping.

In many areas, Red HF was found to free – flow under the cross members and into adjacent compartments even before the actual compartment was completely finished! As for the areas under flanges with extremely thin gaps (< 1/16”, or 1.6 mm), the HF managed to flow under the 12 in (305 mm) wide-flanges in about 30 minutes.
WITH THIS SUCCESSFUL GROUT INSTALLATIONS, SIGNIFICANT GOALS WERE ACHIEVED:
The high percentage of areas under the skid, which lacked necessary flange contact, was partly due to the poor performance of the competitive grout. This created a serious obstacle in providing the crucial layer necessary for support and load transference between the equipment and foundation.
