Grouted tiebacks can be constructed as steel rods drilled through a concrete wall out into the soil or bedrock on the other side. Grout is then pumped under pressure into the tieback anchor holes to increase soil resistance and thereby prevent tiebacks from pulling out, reducing the risk for wall destabilization.
A basement wall is thus one kind of retaining wall; however, the term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top. [2] These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side.
Earth moving equipment (c. 1922) Flattened and leveled construction site. Road roller in the background. Excavation may be classified by type of material: [1]: 13.1 Topsoil excavation; Earth excavation; Rock excavation; Muck excavation – this usually contains excess water and unsuitable soil
The wall face is often of precast, segmental blocks, panels or geocells that can tolerate some differential movement. The walls are infilled with granular soil, with or without reinforcement, while retaining the backfill soil. Reinforced walls utilize horizontal layers typically of geogrids. The reinforced soil mass, along with the facing ...
MSE walls combine a concrete leveling pad, wall facing panels, coping, soil reinforcement and select backfill. [79] A variety of designs of wall facing panels may be used. [79] After the leveling pad has been laid and the first row of panels has been placed and braced, the first layer of earth backfill is brought in behind the wall and compacted.
In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson ' box ', from Italian cassone ' large box ', an augmentative of cassa) is a watertight retaining structure. [1] It is used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ...

An earth anchor is a device designed to support structures, most commonly used in geotechnical and construction applications. Also known as a ground anchor , percussion driven earth anchor or mechanical anchor , it may be impact driven into the ground or run in spirally, depending on its design and intended force-resistance characteristics.
