Super Grout is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a free flowing, non-shrink grout for gap thicknesses up to 100mm
Super Grout is a blend of Portland cement, graded fillers and chemical additives which impart controlled expansion in the plastic state whilst minimizing water demand. The low water demand ensures high early strength. The graded fillers are designed to assist uniform mixing and produce a consistent grout.
Areas of Applications
Super Grout is used for precision grouting where it is essential to withstand static and dynamic loads. Typical applications would be the grouting of base plates of turbines, compressors, boiler feed pumps, bold casting etc., it can also be used for anchoring a wide range of fixings. These include masts, anchor bolts and fence posts.
Features & Benefits
Gaseous expansion system compensates for shrinkage and settlement in the plastic state
No metallic iron content to cause staining
Pre-packed material overcomes onsite batching variations
Develops high early strength without the use of chlorides
High ultimate strength ensure the durability of the hardened grout
Free flow ensures high level of contact with load bearing area
Method of Application
Foundation surface : The substrate surface must be free from oil, grease or any loosely adherent material. If the concrete surface is defective or has laitance, it must be cut back to a sound base. Bolt holes and fixing pockets must be blown clean of any dirt or debris
Pre-soaking : Several hours prior to placing, the concrete substrates should be saturated with fresh water. Immediately before grouting takes place any free water. should be removed with particular care being taken to blow out all bolt holes and pockets.
Base plate : It is essential that this is clean and free from oil, grease or scale. Air pressure relief holes should be provided to allow venting of any isolated high spots.
Leveling shims : If these are to be removed after the grout has hardened, they should be treated with a thin layer of grease.
Form work : The form work should be constructed to be leak-proof. This can be achieved by using foam rubber strip or mastic sealant beneath the constructed form work and between joints.
In some cases it is practical to use a sacrificial semi-dry sand and cement form work. The form work should include outlets for pre-soaking.
Unrestrained surface area : This must be kept to a minimum. Generally the gap width between the perimeter form work and the plate edge should not exceed 150mm on the pouring side and 50mm on the opposite side. It is advisable, where practical, to have no gap at the flank sides
Application Mixing And Placing
Mixing : For best results a mechanically powered grout mixer should be used. When quantities up to 40kg are used, a heavy duty slow speed drill (400-500 rpm) fitted with a paddle is suitable.. Larger quantities will require a heavy duty mixer.
To enable the grouting operation to be carried out continuously, it is essential that sufficient mixing capacity and labour are available. The use of a grout holding tank with provision to gently agitate the grout may be required.
The quantity of clean water required to be added to a 40kg bag
The selected water content should be accurately measured into the mixer. The total content of the Super Grout LP2 bag should be slowly added and continuous mixing should take place for 5 minutes. This will ensure that the grout has a smooth even consistency.
PLACING : At 300 C place the grout within 20 minutes of mixing to gain full benefit of the expansion process.
Super Grout can be placed in thicknesses up to 100mm in a single pour when used as an under plate grout.
For thicker sections it is necessary to fill out Super Grout with well graded silt free aggregate to minimize heat build up. Typically a 10mm aggregate is suitable. 50 - 100% aggregate weight of Super Grout LP2 can be added.
Any bolt pockets must be grouted prior to grouting between the substrate and the base plate.
Continuous grout flow is essential. Sufficient grout must be prepared before starting. The time taken to pour a batch must be regulated to the time to prepare the next one.

Precaution & Limitation
Super Grout LP2 is alkaline and should not come into contact with skin and eyes. Inhalation of dust during mixing should be avoided.
Gloves, goggles and dust mask should be worn.
If contact with skin occurs, it shall be washed with water. Splashes to eyes should be washed immediately with plenty of clean water and medical advice sought. Fire
