SikaGrout®-214 IN is a high-strength, cement-based, one-component, ready-to-mix non-shrink, pourable and flowable precision grout specially developed for demanding engineering and construction applications. It is a two-stage expanding grout designed to provide reliable load transfer and durable filling beneath machinery, structural supports, base plates and other critical components subjected to static and dynamic loads.
The product is supplied as a dry powder and requires only the addition of clean water before application. Its excellent flow characteristics allow the grout to penetrate and completely fill suitable gaps, cavities and spaces where conventional concrete or mortar may be difficult to place. The formulation provides shrinkage compensation and controlled expansion, helping maintain contact between the grout and the surrounding substrate after hardening.
SikaGrout®-214 IN is particularly suitable for machine foundations, turbine and compressor base plates, pumps, boilers, bearings, anchors, precast concrete column joints, penetrations and post-fixing applications.
SikaGrout®-214 IN is formulated from a carefully selected combination of cement, special additives and aggregates.

The product is mixed with a controlled quantity of water to produce a flowable or pourable cementitious grout. Its engineered formulation provides rapid strength development, high final strength and controlled expansion.
The two-stage expansion mechanism helps compensate for initial shrinkage and supports effective contact and load transfer between the grout and the substrate. The product is also designed to provide excellent adhesion to concrete without segregation or bleeding under properly controlled mixing and application conditions.
SikaGrout®-214 IN offers a wide range of properties required for precision engineering grouting:
These properties make SikaGrout®-214 IN particularly suitable for high-precision grouting applications where dimensional stability, strength and reliable load transfer are important.
SikaGrout®-214 IN works through a combination of high-flow cementitious grouting, rapid strength development and controlled expansion.
After mixing with the specified quantity of water, the grout becomes sufficiently fluid to flow into prepared gaps and cavities. The material can be poured into spaces beneath base plates, machinery and structural supports while maintaining continuous contact with the substrate.
During setting, the product provides controlled expansion to compensate for shrinkage. This helps minimise the formation of gaps between the hardened grout and the supported element, thereby improving load transfer.
After curing, the grout develops high compressive and bond strength, allowing it to withstand significant static and dynamic loads.
SikaGrout®-214 IN is widely used beneath heavy machinery foundations where precise and durable load transfer is required.
It is suitable for:
The product is designed for grouting beneath:
Its flowability allows the grout to fill the space beneath the plate while its expansion characteristics help maintain contact after hardening.
SikaGrout®-214 IN can be used for grouting anchors into concrete and for suitable post-fixing applications.
The grout is suitable for column joints in precast construction and other precision connection areas requiring high-strength cementitious grouting.
It can be used to fill suitable cavities, gaps, recesses and voids in concrete structures where a high-strength, non-shrink grout is required.
The product can also be used for sealing suitable penetrations through concrete structures.
SikaGrout®-214 IN develops high early and final compressive strength, making it suitable for demanding engineering applications.
Its shrinkage-compensated formulation helps maintain contact between the grout and surrounding components after setting.
The flowable formulation allows the grout to penetrate difficult-to-access spaces and fill gaps beneath machinery and base plates.
The grout develops substantial strength at an early stage, allowing faster progress of construction and equipment installation where project conditions permit.
The product provides strong adhesion to properly prepared concrete substrates.
Its formulation is suitable for applications involving vibration and dynamic loading.
SikaGrout®-214 IN is chloride-free and designed to be non-corrosive to anchor bolts, base plates, frames and related components.
It is supplied as a ready-to-mix powder; the user only needs to add the specified quantity of clean water.

SikaGrout®-214 IN can be mixed to achieve either flowable or pourable consistency.
Water : Powder = 0.15–0.16 by weight
For one 30 kg bag:
Approximately 4.5–4.8 litres of water
Water : Powder = 0.14 by weight
For one 30 kg bag:
Approximately 4.2 litres of water
The exact water quantity should be selected according to the required consistency while remaining within Sika’s specified limits. Extra water should not be added, as excessive water can negatively affect grout performance.
For optimum results, SikaGrout®-214 IN should be mixed using a suitable low-speed mixer.
Sika recommends avoiding continuous mixing equipment and using full bags for consistent results.
The substrate should be properly prepared before grouting.
Concrete surfaces should be clean, sound and free from dust, oil, grease, laitance, loose particles and other contaminants.
Before application, porous concrete substrates should be brought to a saturated surface dry condition, meaning the surface is damp but free from visible standing or glistening water.
The mixed grout should be poured immediately into the prepared opening while maintaining sufficient pressure head to ensure continuous flow. Air displaced by the grout should be allowed to escape to prevent air pockets and incomplete contact.
For optimum utilisation of the expansion properties, Sika recommends applying the grout as quickly as possible, generally within approximately 15 minutes after mixing.
The recommended maximum layer thickness is approximately:
100 mm
For larger gaps or greater thicknesses, properly washed coarse aggregate may be incorporated according to Sika’s recommendations and after suitable trials. Technical advice should be obtained for critical applications.
SikaGrout®-214 IN is designed for applications involving temperatures from above 0°C up to +200°C, subject to the specific application conditions and manufacturer’s recommendations.
This characteristic makes it suitable for certain industrial environments involving machinery and equipment where elevated service temperatures may occur.
SikaGrout®-214 IN is supplied in:
30 kg bags
The product should remain in its original, unopened and undamaged packaging until required for use.
Store SikaGrout®-214 IN:
The stated shelf life is 6 months from the date of production, provided the product is stored under the recommended conditions.
SikaGrout®-214 IN is a cement-based construction chemical and should be handled using appropriate construction-site safety practices.
Mixing and application tools should be cleaned with clean water immediately after use.
Once SikaGrout®-214 IN has hardened, it can generally only be removed mechanically.
SikaGrout®-214 IN is suitable for a broad range of construction and industrial applications, including:
SikaGrout®-214 IN is engineered for precision applications where ordinary cement mortar or conventional concrete may not provide the required flow, dimensional stability and strength.
Its combination of non-shrink performance, controlled expansion, high compressive strength, excellent flow, strong adhesion and resistance to vibration makes it particularly suitable for machinery foundations and structural engineering applications.
The ready-to-mix formulation also simplifies site operations because contractors do not need to formulate the grout from individual cement, sand and chemical components.
