The integrity of the products we sell, the work we undertake, and the people carrying out that work, are the keys to our success over the last forty years. We look forward to continuing this successful partnership.
Cement grouts continue to be used for the installation of many types of machinery, mainly due to their low initial cost. Increasingly, the overwhelming advantages of polymer grouts for new machinery installation are becoming recognized.
The polymer grouts offered by the Alphatec Group are already extensively tried and proven in many industries around the world – these are not experimental products. There is a growing awareness of the importance of foundations and grout on the long-term performance of rotating machinery.
Many machinery manufacturers are recommending the use of polymer grouts, and a growing number of engineering companies and plant owners & operators are actively specifying their use for the installation of all rotating machinery.
Our polymer products are based on the polyether family of resins; mainly epoxies and vinyl esters. Today’s formulator has an almost endless supply of additives & modifiers available, and the original limitations of the epoxy compound – such as low heat resistance – can be greatly improved. Alphatec 130, our high temperature service polymer grout, which will withstand direct contact temperatures of 150º C, is one example of a properly formulated product.
The benefits of using epoxy grouts are most easily seen in a repair or rehabilitation project, but they will perform very well in new installations of all types of rotating machinery, with the following provisos:
1) The right product for the job must be used. Epoxy grouts come in several flavours: high-temperature types (150°C at the footing); underwater or moisture-tolerant types, which can be very useful when working in the open in a wet climate; low-temperature curing types – good for winter projects, or high latitude/high altitude projects. Please consult us well in advance of the installation date for specific product recommendations, designs and procedures.
2) The product must be used correctly! Make sure the contractor using the product knows what he is doing. If in doubt, ask us to supervise the job, or handle the installation contract directly. The value of the product appears when it has been properly stored, handled, mixed, poured, placed, and finished; under a machine which has been properly prepared, cleaned, deburred, edges ground, corners removed, etc; with anchor bolts that have a suitable embedment length, and a suitable isolated stretch length; on a concrete foundation that has been properly designed, cast, cured, surface prepared, cleaned, etc.
As the only epoxy grout manufacturer with its own contracting arm, Alphatec Engineering is uniquely placed to give you the best combination of products and services.
