Grout is a composite material generally consisting of water, cement, and sand. It is typically used for filling voids under machines or other structural elements, sealing joints and openings in surfaces and reinforcing existing structures.

FAQ's

What is SikaGrout®-212 used for?

SikaGrout®-212 is a cementitious, non-shrink grout designed for applications requiring high-strength, reliable support and load transfer. It can be used for grouting beneath machine and base plates, structural elements and other applications where void filling, dimensional stability and high bearing capacity are required.

Its free-flowing properties allow it to fill gaps and cavities effectively, helping to provide full contact between the grout and surrounding surfaces.

What is non-shrink grout and why is it used?

Non-shrink grout is designed to maintain dimensional stability as it hardens, helping to prevent gaps, settlement and loss of contact between the grout and the surrounding surfaces. This is particularly important where the grout is required to provide reliable bearing and load transfer, such as beneath machinery, base plates and structural elements.

What is grout used for in construction?

Grout is used to fill voids, gaps and cavities and to provide support and load transfer between structural elements. Concrete grouts are commonly used for machine and base plates, anchor bolts, reinforcing bars, precast concrete connections, structural repairs and other applications where high strength and dimensional stability are required.

When should I use resin grout instead of cementitious grout?

Resin grout may be preferred where high bond strength, chemical resistance, vibration resistance or precise load transfer is required. Cementitious grouts are generally more suited to static or predominantly static loading, while resin grouts may be better suited to demanding applications involving significant vibration, impact or dynamic loading. Resin grout can also be suitable for industrial and structural applications involving heavy machinery, anchor bolts, highway fixings and environments exposed to aggressive chemicals.

Can cementitious grout be used for concrete repair and precast concrete?

Yes. Cementitious grouts can be used for a range of concrete repair and new construction applications, including filling voids, reinstating damaged areas, precast concrete connections, bedding joints and anchoring reinforcement. The appropriate grout should be selected according to the required strength, flow, setting time, application method, loading conditions and service environment..

What is free-flowing grout?

Free-flowing grout is a high-strength grout designed to flow easily into voids, cavities, gaps and recesses without the need for extensive compaction. It provides effective filling and contact around structural elements, helping to achievereliable support and load transfer.

Free-flowing grout is commonly used for applications such as machine and base plates, dowelling reinforcing bars, fixing posts and bedding joints in precast concrete sections. Its flow properties allow it to reach difficult or confined areas while providing high strength and good adhesion to concrete.

What type of grout should I use for a specific application?

The appropriate grout depends on the application, required load transfer, loading conditions, substrate, gap size, installation method, environmental conditions and required strength development. Cementitious grouts are generally suited to static or predominantly static loads, while resin grout may be considered for applications involving significant vibration or dynamic loading. Sika offers cementitious and resin grout solutions for applications including machinery bases, structural repairs, precast concrete, highways, anchor bolts and wind-turbine foundations. For critical structural applications, the grout should be selected according to the project requirements and relevant technical specifications.
