HIGH-SPEED GAS COMPRESSOR PACKAGE GROUT BED REPAIR
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 completed installation of Chockfast Red HF using direct-pour, free-flow placement (as an overlay on top a failed in-situ grout and the accompanying bare concrete areas).
IMPORTANT NOTE: What is distinctive about this application is that the original grout used in the installation was not a Chockfast product. The contractor opted to use a competitive product for the installation. When the initial attempt failed, the contractor and end-user contacted us.
THE ORIGINAL GROUT USED IN THE INSTALLATION WAS NOT A CHOCKFAST PRODUCT
After an onsite inspection, it was apparent that the competitor’s product did not each all intended areas under the skid flanging before it began to harden. This created a host of areas under the skid lacking in the degree of necessary coverage and flange contact – and left the contractor and end-user looking for solutions.
GAS COMPRESSOR GROUT BED REPAIRED USING CHOCKFAST RED HF
Skid dimensions (each)
38.0 ft (11582 mm) L x 11 ft (3353 mm) W
Foundation dimensions (each)
39.33 ft (11989 mm) L x 12.33 ft (3759 mm) W
Design grout clearance – 2.0 in (51 mm)
Actual clearance range – 1/16th – 2.0 in (1.6 – 51 mm)
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.
