1.1 Alpha Kogyo, the original ALPHATEC company, had regrouted hundreds of Standun bodymakers in Japan during the 1980s. When the writer came to Singapore, an approach was made to all aluminium can makers in the region, and CMB Singapore just happened to have an immediate problem.
1.2 Vibrations had reached such an extent that anchor bolts had broken, and the machine had been taken out of service. Oil penetration all around was severe, and the small amounts of epoxy grout which had been used to grout the footings could not stem the tide.
1.3 Alphatec Engineering Singapore offered a turn-key service to repair the foundation, remove all oil-soaked concrete and existing grout, replace all the anchor bolts, and align and regrout the machine. Sub-contract labour was employed for this project, but was supervised throughout by the writer.
1.4 Injection holes were drilled into the foundation, and rapidly showed that the depth of the block was not as imagined. However it did show the expected cold joints, indicating that the concrete had not been poured cintinuously. These cold joints were repaired by the pressure injection of ALPHATEC 300 adhesive.
1.5 Since the machine had been removed from its foundation, it was an easy job to attack the damaged concrete. The surprise was the extent to which the damage had gone down into the foundation, necessitating the removal of most of the depth in one area. Build-up of the deepest areas was done with non-shrink grout, which was then covered in layer of epoxy grout covering the entire foundation top.
1.6 The bodymaker was returned to the foundation, supported in place on ALPHAPAD hydraulically adjustable soleplates, and aligned. ALPHATEC 800 epoxy grout was poured to embed the footings properly.
