Pressure grouting or jet grouting [1] involves injecting a grout material into otherwise inaccessible but interconnected pore or void space of which neither the configuration or volume are known, and is often referred to simply as grouting. The grout may be a cementitious, resinous, or solution chemical mixture. Some types of injected grout may ...
A grout curtain is a barrier that protects the foundation of a dam from seepage and can be made during initial construction or during repair. [1] Additionally, they can be used to strengthen foundations and contain spills.
In pool construction, however, shotcrete refers to wet mix and gunite to dry mix. In this context, these terms are not interchangeable. In this context, these terms are not interchangeable. Shotcrete is placed and compacted/consolidated at the same time, due to the force with which it is ejected from the nozzle.
Contaminants can be removed from a site or controlled. One option for control are barrier walls, which can be temporary to prevent contamination during treatment and removal, or more permanent. Techniques to construct barrier walls are deep soil mixing, jet grouting, low pressure grouting with cement and chemicals, freezing and slurry walls ...
Pressure grouting can be low pressure or high pressure. "Jet grouting" is a general term used for high pressure grouting where the high pressure air, water and cementing grout are injected into the ground at high velocity. This can be doing with single tube systems to mix the grout with in situ soil to form a grouted "column" in the ground.
Grout sealer is a water-based or solvent-based sealant applied over dried grout that resists water, oil, and acid-based contaminants. Grout cleaner is a basic cleaning solution that is applied on grout lines and removes the dirt and dust. [9] A die grinder is used for faster removal of old grout compared to a standard grout saw.

This "mud" is injected under the concrete slabs, oftentimes using a movable pump that can access most slabs. Once the void under the slab is filled, the pressure builds under the slab, lifting the concrete back into place. Once in place, the holes are filled with a color-matching grout. Benefits of mudjacking: Low-pressure lifting of slab
