SikaGrout 214-11
Non-Shrink Cementitious Precision Grout for Machinery Bases, Structural Columns, and Anchor Bolts
Authorized Project Distributor — Sika India | Space Arc Engineering, Ghaziabad
Product Overview
SikaGrout 214-11 is a factory-batched, cementitious, non-shrink grout supplied in pre-weighed bags for consistent quality across large-volume machinery installation and structural grouting applications. The non-shrink performance is achieved through a controlled gas-generating expansion mechanism that compensates for the natural plastic-state shrinkage of cementitious grouts, ensuring that the grout maintains full contact between the machine baseplate or column base plate and the supporting concrete foundation throughout curing. This positive contact is critical for machinery grouting: any gap or separation between the baseplate and the grout bed allows dynamic loads and vibrations from the rotating machinery to create impact fatigue on the foundation, eventually cracking the grout and compromising machine alignment. SikaGrout 214-11 provides high early compressive strength development — typically 25 MPa at 24 hours — allowing machinery to be commissioned quickly after installation. The grout is supplied as a dry powder blended with Portland cement, graded aggregates, and expansion agents; it requires only the addition of clean water on site to produce a fluid to stiff grout consistency depending on the water-to-powder ratio used. The fluid consistency allows the grout to flow under baseplates of up to 1.5 metres in width when poured from one side, filling all voids without mechanical compaction in the restricted access under the plate. For larger plates or those requiring pumped grout delivery, SikaGrout 214-11 can be mixed with coarse aggregate (up to 10 mm down) to extend the batch and reduce cost while maintaining non-shrink performance. Space Arc Engineering distributes SikaGrout 214-11 for power plant, industrial, and infrastructure grouting projects across Delhi NCR and Uttar Pradesh.
Applications
- Machinery and equipment base plate grouting — compressors, turbines, pumps, generators
- Structural steel column base plate grouting on reinforced concrete pedestals
- Anchor bolt pocket grouting for heavy structural connections and equipment mounting
- Precast concrete bridge bearing pad grouting and levelling
- Crane rail grouting on gantry girder flanges
- Structural strengthening — grouting under new base plates on existing column capitals
Key Advantages
- Zero-shrinkage (non-shrink) in plastic state — maintains positive contact under base plate
- High early strength — 25 MPa at 24 hours allows rapid machinery commissioning
- Pre-bagged factory quality — consistent mix, no site batching errors
- Fluid consistency available — flows under large base plates without vibration
- Extendable with 10 mm aggregate for large-volume pours at lower cost
- Resistant to oil, vibration, and dynamic loads after curing

Frequently Asked Questions
What is the correct W/P ratio and grouting procedure for SikaGrout 214-11 under a 600mm x 400mm machinery baseplate?
For a 600 mm x 400 mm machinery baseplate, use SikaGrout 214-11 at fluid consistency with a W/P ratio of 0.17 to 0.18 litres per kg (approximately 4.0 to 4.2 litres per 25 kg bag). The grouting procedure: first ensure the concrete foundation surface is mechanically prepared (scabbled or grit-blasted), clean, free of oil, and pre-wetted to SSD condition. Install formwork on three sides of the base plate and on the pour side, leaving a temporary opening higher than the underside of the plate on the pour side. Level and align the machine on wedge packers, with the plate providing a minimum 25 mm clearance to the concrete for grout entry. Mix SikaGrout 214-11 in a mechanical paddle mixer for at least 3 minutes until uniform and lump-free — do not mix by hand. Pour the grout continuously from one side only (not alternating sides) so the grout front pushes air out ahead of it; stop pouring when grout appears at the opposite side and all vent holes. Do not over-pour — stop when grout level is 5 to 10 mm above the underside of the plate on the pour side. Allow 24 hours before removing formwork and at least 72 hours before loading machinery.
Can SikaGrout 214-11 be extended with coarse aggregate for large volume anchor bolt pocket grouting and what is the correct aggregate type and ratio?
SikaGrout 214-11 can be extended with clean, single-size, 10 mm down washed natural gravel or crushed stone aggregate at up to 50 per cent by weight of the dry SikaGrout 214-11 powder — for example, one 25 kg bag of SikaGrout 214-11 extended with up to 12.5 kg of 10 mm aggregate. When using aggregate extension, maintain the W/P ratio based on the dry SikaGrout 214-11 weight (not including aggregate). Add the aggregate to the freshly mixed fluid grout and mix for an additional 1 to 2 minutes. The aggregate extension reduces the heat of hydration in thick sections, reduces cost per cubic metre, and is appropriate for large anchor bolt pockets (100 mm diameter or larger), large column base plate voids (average depth over 100 mm), and bulk fill applications. Do not use aggregate extension for thin sections under 25 mm depth, for machine grouting under vibration-sensitive equipment where maximum strength and zero-void performance is critical, or for areas where grout flow is restricted and the aggregate would cause bridging. For anchor bolt grouting in standard 75 to 100 mm diameter pockets up to 600 mm deep, use fluid SikaGrout 214-11 without aggregate extension to ensure all voids around the bolt are completely filled.
What is the difference between SikaGrout 214-11 and Sika Intraplast Z and when should each be specified for grouting applications in India?
SikaGrout 214-11 and Sika Intraplast Z are both non-shrink grouting products from Sika but serve quite different applications. SikaGrout 214-11 is a complete, pre-bagged, ready-to-use grout — it contains all binder, aggregate, and expansion agent in one factory-blended bag; the user only adds water on site. It provides structural-grade compressive strength (55 to 65 MPa) and is specified as a standalone precision grout for machinery bases, column base plates, and anchor bolts where a complete engineered grout system is required. Sika Intraplast Z, by contrast, is a powder expansion and plasticizing admixture that is added to site-batched cement grout or mortar mixes to provide non-shrink performance — it is NOT a grout product in itself. Sika Intraplast Z is appropriate where large volumes of grout must be batch-mixed on site using local OPC cement and aggregates, and a non-shrink admixture is needed to modify the site-batched mix. Specify SikaGrout 214-11 for all precision machinery grouting, column base plates, and anchor bolt applications where consistent, factory-controlled quality and documented performance data are required. Specify Sika Intraplast Z only for large-volume non-structural or semi-structural grouting where site batching is unavoidable. For critical industrial machinery where machine availability has high commercial value, always specify SikaGrout 214-11.
