PLANNING AND PERFORMING COMPACTION GROUTING

It is pointed out that grouting using a circulating system, although widely used throught the world, is not adaptable to the very stiff mortar-like grouts used in compaction grouting. The system is suitable for thin grouts, but not for either mixing or injecting the nearly "O" slump mixtures involved in compaction grouting. Teh same comments apply to the use of a Colcrete or Cemix type mixer. Compaction grouting and penetration grouting requre differing equipment and procedures. Penetration utilizes "pourable" grout whereas compaction grouting requires grout of a very stiff mortar-like consistency. Many projects in which compaction grouting is used, involve foundation settlement. In such cases, it is common to level structure in addition to stabilizing the faulty underlying soils. Although some levelling can be achieved during the compaction grouting operation, the actual and precise leveling is done following compaction grouting through the injection of similar grout materials between the interface of the settled foundation or slab and underlying soil; injection procedures are utilized that ensure 100 percent filling of all voids to assure support. Such levelling results in the structure, slab or foundation being raised to very precise grades.
