  2. Pressure grouting - Wikipedia

    en.wikipedia.org/wiki/Pressure_grouting

    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 ...

  4. Geotechnical engineering - Wikipedia

    en.wikipedia.org/wiki/Geotechnical_engineering

    There are a number of significant differences between onshore and offshore geotechnical engineering. [16] [17] Notably, site investigation and ground improvement on the seabed are more expensive; the offshore structures are exposed to a wider range of geohazards; and the environmental and financial consequences are higher in case of failure.

  5. Geotechnical investigation - Wikipedia

    A USBR soil scientist advances a Giddings Probe direct push soil sampler.. Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions; this type of investigation is ...

  6. Soil compaction - Wikipedia

    en.wikipedia.org/wiki/Soil_compaction

    In geotechnical engineering, soil compaction is the process in which stress applied to a soil causes densification as air is displaced from the pores between the soil grains. When stress is applied that causes densification due to water (or other liquid) being displaced from between the soil grains, then consolidation , not compaction, has ...

  9. Concrete leveling - Wikipedia

    en.wikipedia.org/wiki/Concrete_leveling

    In civil engineering, concrete leveling is a procedure that attempts to correct an uneven concrete surface by altering the foundation that the surface sits upon. It is a cheaper alternative to having replacement concrete poured and is commonly performed at small businesses and private homes as well as at factories, warehouses, airports and on roads, highways and other infrastructure.
