Optimize Base Support of Machines with Freecem Range of Grouts


Selection of materials for grouting of machines is a key to the long-term performance of the machine in-stalled on the machine foundation. From this point of view, it is extremely important to outline specifications for non-shrink grouts. This is due to the fact that the precision alignments and tolerances have challenged the nature and attributes of the materials to be used for critical applications. Although the cost of the material used for grouting is multifold lower than the cost of the machine itself, the performance of the grout plays a key role in avoiding the breakdown of the machine and its effective performance.

The most important function of a precision grout is to transfer the loads from the machines to the foundation. This can be achieved if and only if the grout after curing and hardening provides one hundred percent contact with the base plate.

The key attributes of a Non-shrink grout

– The grout should have volume stability both in the fresh and hardened state. This can only be achieved if the grout is designed as a dual shrinkage compensating material to achieve the desired volume stability.
– Free Flow – as the clearances and tolerances along with the dimensions of the foundations are challenging, the mixed material of the grout should flow freely without creating any voids in the body of the grout, in order to provide an effective bearing area.
– High Strength – Both early and ultimate strength of the cured grout is important which would decide the time gap between installation and commissioning of the machine on the foundation.
– Modulus of Elasticity – is an important attribute that the hardened grout should possess in order to provide the structural stability of the supporting systems both for dynamic and static loads.
– Chemical Resistance– During the service life of the industry, the grout may be subject to spillage of various materials from the installed machines including oils, acids, chemical fluids etc. on the grout. Hence the hardened grout is expected to be the resistance to chemical abuse during the service life of the industry.




Hence it can be summarized that the grout should possess the following properties.

a) Effective support of equipment
b) Better dynamic and static load resistance
c) Better Chemical Resistance
d) Higher Mechanical Properties such as compressive strength, flexural strength, tensile strength, and bond strength

Keeping in view the above properties, the firm has designed the following grouts and anchor systems to cater to the needs of the industry.

– DynagroutTM – Epoxy resin based 3-com-ponent free flowing high strength grout
– TalrakexpacemTM – Expanding and plasticizing grout admixture
– Freecem S 40/60/80 – Free flow, high strength varying between 40MPa to 80MPa cementitious engineering grout with Dual shrinkage compensation.
– Gripcem® – Single component, cemen-titious anchoring system.
– TalrakpolygripTM – Two component, fast curing, moisture tolerant polyester re-sin based anchoring material for horizontal, vertical and overhead situations.
– SupermicrocemTM GP – Single component, high durable shrinkage compensated injection slurry.
