Chemax GP12 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.
Usage
Chemax GP12 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 etc. It can also be used for anchoring a wide range of fixings. These include masts, anchor bolts and fence posts.
Advantages
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

Unrestrained expansion 2 - 4 % of the plastic state enables to overcome shrinkage
Application instructions
Preparation
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
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.
