Non-shrink cementitious grout. dura.®grout is a ready-to-use (merely add water) Portland cement-based grouting compound. It contains graded siliceous aggregate and chemical reagents which prevent shrinkage during curing.


Consistency range at flowable, fluid or ram to suit application.

Bedding: column base plates, machinery base plates, bearing plates, crane rails.

Grouting: anchor bolts, cables, starter bars, top steel.

Repairing: cavities in concrete.


• Quickly develops placeable consistency.

• Remains cohesive and does not segregate.

• Does not shrink.

Surface preparation

A minimum clearance of 50 mm is required between bed and base.  For smaller areas where the flow will not be restricted, a limited minimum thickness of 25 mm is recommended.  When grouting anchor bolts, three times the bolt diameter is necessary.  Smaller clearances should be grouted with one of the epidermix range of epoxy compounds.

Provision for the escape of entrapped air must always be made.  Contact surfaces must be clean, sound, free from dust and shutter release oils. Concrete surfaces must be thoroughly pre-wetted but excess surface water (free water) must be removed prior to placing the grout. Surface temperatures should not be less than 5 ºC.  Always ensure that the shutters are watertight and sealed to prevent suction of water from the product.

Ensure that the grout delivery head is of adequate height in order to accommodate the distance the grout must flow. Always pour from one side thus ensuring that the grout fills the void without entrapping air.

No primer required but in certain instances where structural bonding is required abe® epidermix 344 should be used.


The water contents specified, apply to 25 kg pockets of dura.®grout. Water quantities must be adjusted to match size of mix. Mixes must always use complete pockets, but more than one pocket may be used. Mixing of grout may be carried out in a pan mixer, drum mixer or by using a slow-speed electric drill fi tted with a suitable paddle. Using the standard 25 kg pocket of grout, add 3.5 liters of clean water to the mixing vessel. While stirring continuously, add the dry powder until the mixture is free from lumps. Then add further water (500 ml to 1 L), continue mixing until a smooth, creamy consistency is obtained. Total mixing time should be approximately three minutes. dura.®grout used as a ram consistency – see mix design under “typical physicalproperties”.


One bag of dura.®grout will yield +12.5 L of grout

(4.5 L water demand)


Mixed grout should be poured into the cavity at one point only to avoid entrapping air.  For best results, mixed grout should be poured within 10 minutes of mixing and definitely within 30 minutes.  If grout is not placed immediately after mixing, keep the material agitated.

Grouting mixture more than 30 minutes old must be discarded. dura.®grout can be compacted by gentle rodding or punning.  It may also be applied by means of standard low pressure grouting pumps.  Do not re-temper the grout should the consistency drop due to time lapse.


Tools, brushes and mixing equipment should be cleaned immediately after use and before material has set with abe® super brush cleaner followed by washing with soap and water.

Protection/maintenance on completion

Grout surfaces should be protected from wind or high temperature, which can cause rapid drying.  Cover the surface with damp sacks.  Do not allow the sacks to dry out; alternatively apply Chryso Cure R or Chryso Cure WB curing compound.


dura.®grout is supplied in 25 kg polyethylene lined paper bags.

Handling & storage

Shelf life of 12 months, but shorter if in extreme conditions.  Keep tightly sealed in a dry cool place in the original packaging.

Health & safety

Product safety information required for safe use is not included.  Before handling, read product and safety data sheets and container labels for safe use, physical and health hazard information.  The safety data sheet is available from your local a.b.e.® Construction Chemicals branch.
