ALPHATEC 370 is similar to ALPHATEC 342 above, but is specifically formulated to have excellent tolerance to oil-contaminated surfaces, which are so common in machine foundations. Description : ALPHATEC 370 is a two-component polymer grout injection system consisting of modified epoxy resin and chemical hardener. ALPHATEC 370 is specially formulated for oil tolerance, and shows good bond to oil-soaked concrete and other contaminated surfaces. It is widely used for the repair of machinery foundations that have been in service for a number of years, such as diesel engines, compressors, blowers, pumps, presses, and so on. Features : Cures within 24 hours Fills cracks down to 0.05 mm Also bonds well to damp or wet concrete Injection by HP or LP methods

In order to avoid cold joints (q.v.) in new foundations, the use of ALPHATEC 440 is ideal, as it has excellent bonding qualities to already cured concrete, long pot-life which allows for enough time to prepare for the next pour, and good resistance to being scoured from the surface. Description : ALPHATEC 440 is a modified epoxy resin-based concrete primer with good tolerance for wet surfaces. It can be applied on concrete, wood, or steel surfaces, and shows tenacious adhesion even when cured in the presence of water. It forms a good basis for the application of lining, flooring, or patching mortar systems, particularly when surface preparation methods such as high-pressure water blasting are the only practical approach. ALPHATEC 440 is used in underwater repairs of jetties, piers and wharves, as well as in wet areas in industrial plant such as steel rolling mills. It is frequently used in conjunction with ALPHATEC 741 Patching Compound. Features : Good bond to wet surfaces Fast cure 2 hours at 25 ° C Compatible with most topcoats Easy to apply

ALPHATEC 240 is a heavy paste consistency material which can be mixed and placed by hand. It has excellent adhesive properties, and is widely used for sealing grout forms, which must be liquid-tight. Description : ALPHATEC 240 is a two-component epoxy putty system consisting of modified epoxy resin paste and a chemical hardener. It has good water displacing properties allowing it to bond to wet surfaces, and cure underwater. It bonds well to steel and concrete surfaces, and cures rapidly. It is used for sealing grout forms, patching concrete, patching steel tanks, setting base plates in position, and so on. Features : Easy mixing & application by hand Cures at temperatures down to 5 º C Good bond to wet surfaces Good mechanical properties

ALPHATEC 741 Patching Compound is based on the same resins as AT 141, but has a different filler system, which allows it to be used on vertical and overhead surfacses. This product is also widely used on wet concrete surfaces and can also be used to repair jetties, mooring dolphins and other marine structures. Description : ALPHATEC 741 is a fast curing epoxy patching mortar for application on wet concrete surfaces. It has excellent workability, and the non-slump characteristics are such that 20 to 30 mm can be applied overhead on a flat surface without sagging. ALPHATEC 741 is supplied as a pre-measured 3-component kit, thus requiring no weighing of components in the field. ALPHATEC 741 has been used to repair wharves, jetties, mooring dolphins, and various other marine structures, as well as concrete foundations in wet areas in steel mills, basements, etc. Features : Fast cure at ambient temps Cures at temperatures down to 0 ° C Very low water absorption Slump resistant

ALPHATEC 141 Epoxy Grout has the proven ability to cure underwater, and has been used in a number of wharf and jetty repair projects, as well as in industrial processes where the concrete foundations are continually wet. Description : ALPHATEC 141 is a three-component polymer grout system consisting of modified epoxy resin, chemical hardener, and blended aggregate. ALPHATEC 141 is formulated for fast cure in immersed conditions, and will attain strength of 23 MPa within 4 hours when mixed and placed at 23 º C It can be used at operating temperatures of up to 50 º C. Features : Rapid curing in air or under water Good properties in air & water Medium aggregate loading Good bond development under water 

Our proprietary method of injecting epoxy resins and regrouting machinery ensures a prolonged life for equipment which is suffering vibration problems, excessive wear and tear on moving parts, misalignment, or whose foundation appears damaged.

Process plants around the world depend on millions of rotating machines: compressors, pumps, blowers, fans, presses, generators, mills, mixers, and so on through a long list. The maintenance department is generally pretty busy keeping these machines together, repairing them, and making sure they are available for production. Mis-alignment causes excessive vibration, increased power consumption, reduced output, and wear and tear on components. But the major cause of mis-alignment � grout failure - is very rarely diagnosed. During the last 35 years or so our group of companies has regrouted and repaired the foundations for thousands of rotating machines in all types of industrial plant. We are able to restore a machine to a condition which is close to original, or even better in cases where �original� was actually sub-standard. The basic philosophy behind our approach to foundation repairs is to restore the integrity of the concrete block and to assure that it performs its functions as a vibration damping device � the primary purpose of a foundation. Having identified the cracks and separations, we design a repair procedure to resolve the cause or causes of the cracking, and not merely fill the cracks themselves. The premises upon which we base our work are: he concrete foundation is the main vibration absorbing element of the installation, provided that it is of sufficient mass; that it is one integral whole; and that it is properly connected to the machine. - The primary cause of a foundation�s inability to attenuate vibrations is the cold joint (see cold joint). Use of an epoxy bonding agent is the only way to obtain full adhesion between pours, and its use is rare. Most foundations therefore have this inherent problem, which can be corrected by Alphatec�s epoxy injection process. The best way to ensure that the foundation is correctly connected to the machine is to use epoxy grout, and good anchoring techniques. - The photo on the right reveals bad install
