  • Grouting operate to reinforce expanded clay ground. Cement grouting is one of the most frequently used techniques for underground construction. This work is going to use to add an electrolytic ion to boring water for expanded reduction. To construct underground structures on expanded clay ground is operated pre-grouting that it is the barrier wall previous excavation to prevent an accident. Grouting for early compressive strength development is made a type of suspension. That grouting aims to prevent the swelling magnification in length of time. From now on, grouting is became a type of higher strength suspension to develop early compressive strength.
