SikaGrout®-214

High Performance, Non Shrink, Expanding Cementitious Grouting Mortar

Sikagrout® -214 is a high performance, shrinkage compensating, ready to use grouting mortar. Consisting of :

  • A blend of cement & fillers,
  • Properly graded quartz aggregates,
  • And Special additives.
When mixed with water, the product forms a fluid grey coloured grout (similar to concrete colour).

- Sikagrout® -214 is chloride free and contains no metal particles. Consequently, it does not oxidize when in contact with humidity. Instead it protects metal parts from corrosion owing to its high alkaline Ph. - It has a unique 2-stage shrinkage compensating system, with a very special blend of shrinkage and water reducing, plasticizing agents, offering the following beneficial properties:
  • High mechanical compressive and bending resistances.
  • Adheres to concrete, mortar and steel, ensuring a monolithic bond.
  • Can be pumped, injected, vibrated or compacted. It's not altered by large humidity or temp. variations.
  • Resistant to water and oil penetration.
  • High initial strength reduces down time requirement.

The above proportions should be complied with to avoid bleeding.

Layer thickness

From 12 mm up to 50mm without Filler

Adding Fillers

- For large scale grouting projects, silica sand and gravel can be added to   Sikagrout® -214, where the added aggregate must be clean and properly graded.

- Example: 12.5 kg of sand graded 1-10 mm to one 25 kg bag of Sikgrout® -214 mixed with 3.5 – 4 lts. of water, yield a grout with the following approximate mechanical strengths:

Application steps

APPLICATION INSTRUCTIONS

Surface Preparation

- The substrate must be properly prepared and free of dust and grease. Remove any losses particles which could affect the final ultimate bond strength.

- Moisten concrete or mortar substrate for 12 hrs. before applying Sikagrout®  -214 (surface saturated dry condition SSD). This is extremely important during hot weather applications.

MIXING

Blend in a mechanical mixing device, preferably in a vertical-axis mixer or in a fully opening container, using a slow- rotating electric or pneumatic stirring drill (approx. 500 rpm).

Prepare the amount of water required to obtain the right consistency (refer to mixing ratio). Pour approx. 2/3 of the mix water into the container and gradually add Sikagrout® -214, this will help to avoid making lumps. Then pour in the rest of the water and let mix for a minimum of 3 minutes from the time the last water was added to the mix.

NOTE: Hand mixing does not ensure proper dispersion and is not recommended.
Recommended to use either low speed (max. 500 rpm) electric drill with a basket type mixing paddle or forced action – or stand type mixers

APPLICATION

Minimum application temperature: + 5 ºC.

- For anchoring dowels and bolts the minimum annular space around the shaft is three times, the diameter of the largest grains in the mortar mix.

- Pour grout immediately after mixing. Ensure that air displaced by the mortar can easily escape; otherwise entrapped air will prevent full contact grouting. Wet porous substrates to saturated surface dry condition.

- When grouting base plates etc., ensure that a continuous and sufficient head of pressure is maintained to keep the grout flowing.

- To make optimum use of the products expansion properties, apply the grout as quickly as possible (within max. 15 minutes).

Pre-cautions

  • Sikagrout® -214 is always added to the pre-measured gauging water.
  • Volume of water must always be within the limits as stated in our Technical Data Sheet.
  • Excess water, will cause cracks, segregation and low grout strengths.
  • Sikagrout® -214 should be left to stand after final mixing, for 5 minutes, allowing any entrapped air to dispel.
  • To take full advantage of Sikagrout® -214 expansion properties.
  • Sikagrout® -214 should be poured /placed as soon as possible from 5 minutes standing, up to 30 minutes from mixing
  • Kindly refer to Sikagrout® -214 Method Statment and technical office.

CURING TREATMENT

- After placement of Sikagrout® -214, exposed surface area has to be fully cured for a minimum period of 3 days from achieving its initial setting: Or directly bleeding water have evaporated.
Sika Antisol® - E curing compound may also be used to ensure ultimate curing.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use. Hardened/cured material can only be mechanically removed.
