Pressure grouting is a specialized waterproofing and structural repair technique in which grout is injected into cracks, voids, and gaps in concrete under controlled pressure. The injected grout fills internal cavities, strengthens weak areas, and blocks pathways through which water can seep.
This method is highly effective for stabilizing damaged structures and restoring their load-bearing capacity. Pressure grouting is commonly used where conventional surface waterproofing methods are not sufficient to control leakage.
