A DPC layer is usually laid below all masonry walls, regardless if the wall is a load bearing wall or a partition wall. A damp-proof membrane (DPM) is a membrane material applied to prevent moisture transmission. A common example is polyethylene sheeting laid under a concrete slab to prevent the concrete from gaining moisture through capillary ...
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.
These dams are characterized by a slender vertical puddle clay core supported on both sides by earthfill shoulders of more heterogeneous material. To control under-seepage through the natural foundation below the dam, the Pennines embankments generally constructed a puddle clay-filled cutoff trench in rock directly below the central core.

Schematic cross section of a pressurized caisson. 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] 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 ships.
Many dams and their associated reservoirs are designed completely or partially to aid in flood protection and control. Many large dams have flood-control reservations in which the level of a reservoir must be kept below a certain elevation before the onset of the rainy/summer melt season to allow a certain amount of space in which floodwaters ...
