  • Pump Grouting

    This issue deals with a subject that is equally as important as the grouting of reciprocating machinery, yet is rarely covered in the installation bulletins of grout manufacturers. Some useful techniques for "two-level" pump grouting have been developed in the last few years, and they are yielding better performances than older techniques. to aid you in the selection of particular conditions.

  • Repairs of Cracks in Epoxy Grouts

    Epoxy Grouts most epoxy machinery grouts will develop cracks in long or wide epoxy grout caps if subject to different environmental temperatures. Vertical cracks usually occur at a stress concentration point, such as an anchor bolt or jackscrew landing plate.

  • Proper Job Planning 2

    Planning the Pour Planning the grout pour is one of the most important steps necessary to insure a good grout installation. Many steps need to be taken early in the job schedule, several days ahead of actual grouting in some cases. Items such as the following fall into this category:

  • Pressure Grouting of Voids Under Machinery Bases

    Description After drilling the initial hole or holes into a void, the depth of the void can be determined by measuring the penetration of a stiff wire. Additional holes can also be drilled to confirm the extent of the void. If the depth checks indicate consistent voids of over 1/4” in thickness, then a filler will need to be added to the normal two-part liquid Warning grouts.

  • Anchor Bolts - The Forgotten Connection

    For several years, strict attention has been paid to good grouting materials and installation techniques, particularly with the devolpment of epoxy grouts. In more recent years, the vital role of anchor bolts is being recognized as just as important as the grout under the machine.

  • Reinforcing Deep Epoxy Grout Pours

    Epoxy machinery grouts were originally designed for critical machinery, such as large compressors, engines and turbines. With such applications, typical grout pour depths were 1 1/2" to 2" and on new concrete.

  • Expansion Joints

    Expansion joints are very important in epoxy grout pours as they serve to limit the cracking that can often occur in the grout. Cracks are the result, generally, of a curing stress that develops in the grout as it hardens. Grouts generate heat after they are mixed and the chemical reaction starts. The hotter the exothermic chemical reaction (necessary to develop a high compressive strength grout)

  • Grouting Problems - Machinery Foundations

    After 65 plus years of experience in precision equipment grouting with cementitious and epoxy grouts, a variety of problems have been seen. Certain problems crop up repeatedly, indicating that better education and written instructions should be directed toward the most frequently encountered problems.

  • Proper Job Planning

    Earlier issues of this newsletter have covered topics such as "What is Grout", "The Different Types of Grout", and "Foundations-Preparation for Grouting". If you did not get those issues and want copies, please call or write to us at the address below. Planning the Pour Planning the grout pour is one of the most important steps necessary to insure a good grout installation. Many steps need to be t

  • Foundations - Curing, Inspection and Preparation

    Equally as important as the types of machinery grouts (organic and inorganic) available, which were discussed in earlier issues of the Grouting Technology Newsletter, is the concrete foundation itself.

  • What Are The Different Types of Grout?

    In our last newsletter, we referred to two distinct classes of machinery grouts, inorganic and organic. A brief discussion of each type will shed some light on where each should be used.

  • What is Grout?

    This first issue in a series of technical newsletters is designed to provide practical help to people in the field who install grouting materials. It will also provide, in subsequent issues, design tips to help engineers and equipment technicians in the proper selection of materials and installation details that will insure better grouting designs and specifications.
