An OEM was working on a major refurbishment of a 2-cylinder reciprocating processor at a refinery in Germany. After the machine had been disassembled, the underlying foundation turned out to be in such a poor condition (cracked grouting, tears in the concrete base, failing anchor bolts, oil penetration in the concrete layer, etc.) that it had to be completely repaired.
After visiting the site, EMHA consulted with the client and decided to re-anchor and grout the entire machine with Chockfast red epoxy grouting. The old anchor bolts were removed with diamond drills and replaced with new epoxy grouted anchors, designed with the help of the EMHA calculation tool.
All oil-contaminated concrete was removed and re-applied with Chockfast. The compressor extension supports were fitted with EMHA-designed soleplates, which ensure that the machine will be easy to disassemble for future maintenance and that the new grout layer will not have to be partially demolished. The entire foundation was treated with an AQ-paint 2K epoxy system to prevent oil, moisture and other contaminants from penetrating into the concrete.
