Grouting is a versatile technology for creating sheeting, foundation piles or for strengthening existing foundations. The technique involves the high-pressure injection of cement into the soil. The high pressure flushes away the soil, thus creating underground cement columns.
When we use grouting for sheeting a construction pit, we prefer to work with half piles, so-called segment piles. This avoids space loss in the construction pit.
When excavating the construction pit, it is important to anchor the walls for horizontal stability.
