Soil-cement columns built by erosion<\/strong><\/p>\n<\/div>
Whether it’s a dam and its watertightness, a tunnel and its consolidation, or the securing of quarries, Soletanche Bachy masters the entire range of injections to meet your needs.<\/p>\n<\/div>
Grouting into a soil or around a structure makes it possible to render soil impermeable and\/or fully consolidated by filling its voids with a pumpable product (grout) that subsequently sets hard.<\/p>\n
Grout can be used to fill voids in soil, cracks in rock and voids caused by dissolution (referred to as crack, impregnation or cavity filling grouting<\/strong>), and\/or penetrate by displacing the soil by means of pressure or hydrofracturing (this is referred to as compaction grouting or solid grouting and hydrofracture grouting.<\/strong>). Displacement grouting can be used to limit structural deformation as a result of excavation (galleries and tunnels, large-scale urban excavations, etc.); this is referred to as compensation grouting<\/strong> (of structural settlement).<\/p>\n
Grouting is always injected by drilling, often using devices to control the flow of grout into the soil (injection tubes, obturator bags, \u201ctubes \u00e0 manchettes\u201d, etc.)<\/p>\n<\/div>
