SikaGrout 212 Non-Shrink Engineering Grout 25kg in Nairobi, Kenya
A ready-to-mix, free-flowing cementitious grout for machine bases, steel base plates, anchor bolts and void filling. Just add water, mix and pour. Available at Shabbiri Hardware, Magadi Road, Ongata Rongai and Tuala.
Product Overview
SikaGrout 212 is a one-component, pre-batched, non-shrink cementitious grout made by Sika, the global leader in construction chemicals. It comes as a grey powder in a 25 kg bag and only needs clean water to turn into a smooth, free-flowing grout.
Because it is shrinkage compensated, SikaGrout 212 fills the full space under base plates and around bolts without pulling away as it hardens. This gives a solid, load-bearing bed that transfers weight evenly into the concrete below. It bonds well to concrete, does not bleed or segregate, contains no corrosive agents, and can be either poured or pumped.
Contractors, engineers and fundis across Nairobi use SikaGrout 212 for grouting machine foundations, steel column base plates, anchor and holding-down bolts, starter bars and precast concrete joints. It is one of the most trusted engineering grouts in Kenya.

Anchor & Holding-Down Bolts
Fixing anchor bolts, post fixings and holding-down bolts into pockets.
Dowelling Rebar
Grouting starter bars and dowels into drilled holes or pockets.

Filling confined cavities, voids, gaps and recesses in concrete.
How to Use SikaGrout 212
1Prepare the Surface
The concrete must be sound, clean and free from dust, loose particles, oil, grease and laitance. Remove anything that could weaken the bond.
2Pre-Wet the Concrete
Soak the concrete with clean water, ideally for several hours before grouting. Just before pouring, remove all standing water so the surface is damp with no puddles.
3Set Up Formwork
Fix strong, leak-proof formwork around the base plate or opening, with a head box on the pouring side so grout flows under the plate from one side only.
4Measure the Water
Pour 3.25 to 3.75 litres of clean water per 25 kg bag into a clean mixing container. Never go above this amount.
5Add Powder and Mix
While stirring slowly, add the powder to the water. Mix with a slow-speed drill and paddle (below 500 rpm) for at least 3 minutes until smooth and lump-free. Mix full bags only.
6Let It Stand
Allow the mixed grout to stand for about 2 to 3 minutes, then give it a short stir with a trowel.
7Pour the Grout
Pour continuously from one side only so air escapes from the other side. Use within about 20 minutes. Use steel strapping to help flow if needed, or a grout pump for large volumes. Do not vibrate.
8Cure Properly
Protect fresh grout from fast drying, sun and wind with a curing compound, wet hessian or a moist geotextile membrane.
9Clean Tools
Wash all tools with water immediately after use. Hardened grout can only be removed mechanically.
Important Precautions
- Do not add more water than the recommended dosage.
- Do not add extra water after mixing or after application, as this can cause cracking.
- Not for use as a patch repair or as an overlay in unconfined areas.
- Apply only to sound, properly prepared concrete.
- Avoid pouring in direct sun or strong wind.
- Keep exposed grout surfaces to a minimum.
- Do not vibrate the grout.
- Wear gloves and eye protection. Cement powder irritates skin and eyes.
How Many Bags Do I Need?
Work out the volume to fill in litres (length × width × depth in metres × 1,000), then divide by 12.5. Add about 10% for waste.
Example: a base plate area of 0.6 m × 0.6 m with a 40 mm gap needs 14.4 litres. That is about 1.2 bags, so buy 2 bags.

Frequently Asked Questions
How much water do I add to a 25 kg bag?
Use 3.25 to 3.75 litres of clean water. Too much water lowers the strength and can cause cracking.
Is SikaGrout 212 available in smaller packs?
No. It is only supplied in 25 kg bags.
How long before I can load the machine or column?
Strength builds quickly over the first week. Your engineer should confirm when loading is safe for your job.
Can I use it to repair broken concrete?
No. It is a grout for confined spaces. For concrete repairs, ask us about Sika MonoTop repair mortars.
Do you install the grout?
Shabbiri Hardware is a supplier only. We can share contacts of independent fundis and contractors on request.
